This booklet examines baptism through five key questions:

• What Is Baptism?
• Who Is Baptism For (And Why Not Babies)?[1]
• Why Is Baptism Required For Church Membership?
• When Is “Baptism” Not Truly Baptism?
• How Should Churches Practice Baptism?[2]

A Pastoral Preamble
Baptism is a fraught and complex issue—theologically, historically, and often personally. It is not a first-rank doctrine on which the gospel itself rises or falls; genuine Christians on both sides of the credobaptist-paedobaptist divide share the same Savior, the same gospel, and the same eternal hope. But baptism is still a serious second-rank doctrine because it concerns obedience to Christ’s express command and the visible shape of the church’s life together. That means it requires both firmness and kindness: firmness, because Christ has not given us permission to soften His commands for the sake of comfort or convenience; kindness, because those who disagree with us are not enemies, heretics, or lesser Christians. Our aim throughout this booklet is to be irenic in tone and clear in conviction. We will not bend biblical-theological convictions to accommodate traditions we believe are mistaken, but neither will we treat those who hold such traditions as anything less than dearly loved fellow members of Christ’s body.

The Biblical Definition
Baptism is a church’s act of immersing a believer in water whereby it affirms and portrays the believer’s death to sin, separation from the world, union with Christ, and public commitment to Christ and His church.[3]

Let’s briefly examine each component of this definition.

A Church’s Act
The Christian life is inherently a churched life.[4] This fundamental biblical conviction shapes our understanding of baptism and its role in the life of both individual believers and the church as a whole.

So, while baptism always involves two parties—the baptizer and the baptized—it represents the church’s exercise of Christ’s delegated authority to make public declarations on heaven’s behalf. This authority was first given to the apostles (Matthew 16:19), then to local churches (Matthew 18:18-20; 28:18-20), but never to individuals.[5] While frontier missionary situations may necessitate baptism without an established church present, ordinarily it should be performed under church authority. Despite modern individualism’s pressure to the contrary, baptism is not a freelance gesture but a churchly act of kingdom recognition.

Immersing A Believer In Water
When it comes to the essential mechanics of how to baptize, the mode is inherent in the word. As Dr. Sam Waldron points out, its literal and figurative usage in secular Greek, the Septuagint,[6] and the New Testament all clearly confirm that “baptism literally means to immerse and figuratively means to overwhelm.”[7] To baptize is to submerge, plunge, dip, and bathe—as in a ship sunk in battle and a turnip pickled in vinegar—so the thing baptized is transformed into a new state of being.[8]

This argument for immersion as the normative mode in the New Testament is verifiable from three assertions:

(1) When the New Testament speaks of the physical act of baptism, it only refers to immersion in water.[9] Mark 1:5 says, “And all the country of Judea and all Jerusalem were going out to him and were being baptized by him in the river Jordan, confessing their sins.” Acts 2:38, 41 say, 38 “And Peter said to them, ‘Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.’ 41 So those who received his word were baptized, and there were added that day about three thousand souls.” Acts 8:12 says, “But when they believed Philip as he preached good news about the kingdom of God and the name of Jesus Christ, they were baptized, both men and women.” Acts 16:33 says of the Philippian jailer, “he was baptized at once, he and all his family.” Acts 18:8 says, “many of the Corinthians hearing Paul believed and were baptized.” Acts 19:5 says of Paul’s Ephesian converts, “On hearing this, they were baptized in the name of the Lord Jesus.” The cumulative force of these and the dozens of other occurrences cataloged in the footnote is decisive: the Greek vocabulary the New Testament writers chose for the physical rite of baptism is, in every single instance, vocabulary that means to immerse, to submerge, to dip under. Note also what is conspicuously absent—Greek has a perfectly serviceable verb for “to sprinkle” (rhantizō), used in Hebrews 9:13, 19, 21 and 10:22 of Old Testament cleansing rituals, and yet that verb is never once used to describe Christian baptism in the New Testament. The Spirit-inspired writers had a word for sprinkling and they didn’t reach for it. They reached for baptizō. That is not a coincidence; that is a deliberate exegetical signal.

(2) When the New Testament speaks of the physical act of baptism, the context logically requires immersion. In Mark 1:9-10, 9 “Jesus … was baptized by John in the Jordan [not beside or with, as might accompany sprinkling or pouring] … and when he came up out of the water….” Same in Acts 8:38-39, 38 “they both went down into the water, Philip and the eunuch, and he baptized him. 39 And when they came up out of the water….” John 3:23 records that “John also was baptizing at Aenon near Salim, because water was plentiful there”—a curious editorial detail unless John required substantial water to do what he was doing. (You don’t need a lot of water to sprinkle.) Matthew 3:16 says of Jesus’ baptism, “And when Jesus was baptized, immediately he went up from the water…”—language that only makes sense if He had first gone down into it. Matthew 3:6 describes John’s baptismal ministry as taking place “in the river Jordan”—a river, not a basin. The geography, the prepositions, the verbs of motion—into, out of, come up, go down—all of it is wasted vocabulary unless what is being depicted is full-body immersion. Sprinkling does not require a river, plentiful water, or descent and ascent. Immersion does.

(3) When the New Testament speaks of baptism metaphorically, the imagery draws its meaning from immersion in water.[10] For example, in Mark 10:38-39, Jesus describes His coming suffering as a baptism: 38 “Jesus said to them, ‘You do not know what you are asking. Are you able to drink the cup that I drink, or to be baptized with the baptism with which I am baptized?’ 39 And they said to him, ‘We are able.’ And Jesus said to them, ‘The cup that I drink you will drink, and with the baptism with which I am baptized, you will be baptized.’” The metaphor only works because baptism literally means to be submerged—Jesus’ death will overwhelm Him like a flood (cf. Psalm 88:7; Jonah 2:3-5). Same in Romans 6:3-4, where Paul appeals to immersion’s burial imagery: 3 “Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.” Sprinkling cannot picture burial; only immersion can. Colossians 2:12 makes the identical move: “having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.” And in 1 Corinthians 10:2, Israel is “baptized into Moses in the cloud and in the sea”—with the cloud over them and the sea walls towering on either side, a complete envelopment in the saving event. In every case, the metaphorical baptism draws its rhetorical punch from a literal, physical immersion. As Tom Schreiner observes, “Most scholars agree that immersion was practiced in the NT,”[11] precisely because the NT writers reach for baptizō whenever they need a verb that means total enveloping, total transformation, total burial-and-rising.

Whereby The Church Affirms And Portrays
Baptism is a church’s act of immersing a believer in water whereby it affirms and portrays the believer’s death to sin, separation from the world, and union with and commitment to Christ and His church. Two verbs do the heavy lifting here—affirms and portrays—and they distinguish baptism from any private religious gesture. Together they ground baptism in the church’s Christ-given authority and in the gospel itself.

First, baptism affirms. It is a public, declarative act in which a local church—weighing what it has heard, observed, and discerned—“goes on record” on heaven’s behalf that the one being baptized credibly belongs to Christ. This is the keys-of-the-kingdom authority Jesus gave His church (Matthew 16:19; 18:18-20; 28:18-20). The church does not create the union with Christ; it ratifies and seals what God has already done by grace through faith. Baptism is where invisible faith first becomes visible to the gathered body and the watching world. The judge’s gavel doesn’t write the law or change the facts—it pronounces a binding verdict on what the law and the facts establish. So with baptism: it is the church’s authoritative “Amen” to a credible profession of faith.

Second, baptism portrays. It is a vivid, embodied picture—a living drama performed in water—of what God has wrought in the heart of the one being baptized. Baptism is meant to be symbolic, an outward sign of an inward reality. The motion itself dramatizes the gospel: Christ crucified, buried, raised; and the believer crucified, buried, raised with Him (Romans 6:3-4; Colossians 2:11-12; cf. 1 Corinthians 15:3-4). Excavations of early-church baptistries reveal a striking detail—many were built in cruciform shape (death and burial) or octagonal shape (the resurrection on the “eighth day” that begins the new creation), and the patristic writers regularly described the baptismal font as a tomb of the old self and a womb of regeneration.[12] All of this gave visible expression to the death-and-life imagery the early Christians saw embedded in the rite.

To say that baptism is “merely symbolic” badly underestimates the kind of symbol Scripture has in view. This is not “only a symbol” or “just a symbol”—as if the rite were a mere form lacking real significance. Baptism is indeed a symbol—but a symbol packed with spiritual significance. It is not just an external rite but a spiritual event the Holy Spirit uses to enrich and bless both the candidate and the gathered congregation. It is not at all uncommon for a believer to look back on his or her baptism and say, “It was one of the most meaningful experiences of my life. I’ll never forget it.” That is exactly how it ought to be.

So in baptism, the church speaks for God to the believer: “We see Christ in you—you belong to Him.” And the church speaks for the believer to the world: “Look here! This one belongs to Jesus.” What God has joined in the gospel, baptism affirms with a verdict and portrays with a picture.

A Believer’s Death To Sin
The first reality baptism affirms and portrays is death—specifically, the believer’s decisive death to sin’s reigning power. Romans 6:3-4 is the classic text: 3 “Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.” Paul does not say baptism creates this death to sin; he says baptism declares and dramatizes it. The believer was “buried” with Christ “by baptism into death,” and the going-under-water—the literal funereal motion of immersion—pictures the burial that followed Calvary.

Three threads of biblical teaching reinforce this:

• Sin’s reigning power has been broken. Paul’s whole argument in Romans 6 is that the Christian cannot continue in sin because he has “died to sin” (Romans 6:2). Baptism is the public dramatization of that decisive break. The old self—“enslaved to sin” (Romans 6:6), formerly walking as “sons of disobedience” (Ephesians 2:1-3)—has been crucified with Christ. The aorist passive ebaptisthēmen, (“we were baptized”) in Romans 6:3 looks back to a definitive, completed event: the death has already happened.

• Sin’s record has been cleansed. Ananias tells the converted Saul, “And now why do you wait? Rise and be baptized and wash away your sins, calling on his name” (Acts 22:16). Peter at Pentecost ties baptism to “the forgiveness of your sins” (Acts 2:38). The cleansing imagery is rooted in the Old Testament washings (Numbers 19; Ezekiel 36:25-27) and in the Jewish mikvah tradition of ritual cleansing pools, where the body’s complete submersion under water dramatized the soul’s complete cleansing before God. But the power for the cleansing lies not in the water itself but in “an appeal to God for a good conscience, through the resurrection of Jesus Christ” (1 Peter 3:21). The water signifies; the resurrection saves.

• Sin’s chronic patterns are repudiated. Paul connects baptism to “putting off the body of the flesh, by the circumcision of Christ” (Colossians 2:11-12). The image is surgical—a decisive cutting away of the old sinful nature, performed not by human hands but by the Spirit applying Christ’s saving work to the believer.

This is why baptism so often functions as a watershed moment for new believers. Believers come to Christ with histories of old behaviors and old allegiances and old patterns; baptism provides a mile marker from which their history begins all over. It announces, before God and the gathered church, that the line has been drawn—the believer has died to the old life and is being raised to walk in a new one.

A Believer’s Separation From The World
If baptism dramatizes death to sin, it equally dramatizes separation from the world. To rise from the water is not just to leave behind the old self; it is to step out of one community—“this crooked generation” (Acts 2:40)—and into another. Baptism is a covenantal boundary marker, and the New Testament builds this case from several angles:

• Walk in newness of life (Romans 6:3-4). Resurrection with Christ is not abstract; it produces a visibly different life that distinguishes the believer from the world’s patterns and values. The contrast between the buried “old man” and the resurrected “new man” is meant to be observable.

• Put on Christ as a garment (Galatians 3:26-27). 26 “for in Christ Jesus you are all sons of God, through faith. 27 For as many of you as were baptized into Christ have put on Christ.” The Greek enedusasthe, (aorist middle indicative, “you have clothed yourselves”) pictures baptism as putting on a new identity that visibly distinguishes the wearer from those still wearing the world’s clothes.

• Buried with Him in baptism parallels covenantal circumcision (Colossians 2:11-12). 11 “In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism….” In the OT, circumcision was the covenant sign that marked Israel off from the surrounding nations. Paul makes baptism the new-covenant analog—not in mode (cutting flesh) but in covenantal function (marking out a people).

• Saved through water as Noah was (1 Peter 3:20-21). 20 “because they formerly did not obey, when God’s patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water. 21 Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ.” The flood typologically separated those saved from those perishing in judgment; baptism marks those who belong to God’s covenant community from those outside it.

• Save yourselves from this crooked generation (Acts 2:40-41). Peter’s exhortation to separate and the immediate response of baptism are not coincidental. Baptism is how that separation gets publicly enacted—stepping out of the crowd of the unbelieving world and into the assembly of the redeemed.

• Baptized into one body (1 Corinthians 12:13). Baptism incorporates believers into a distinct community—“Jews or Greeks, slaves or free”—that transcends the world’s divisions and necessarily entails separation from its allegiances and systems.

This separation isn’t sectarian withdrawal; it’s covenantal allegiance. Jesus said, “Therefore everyone who acknowledges me before men, I also will acknowledge before my Father who is in heaven, but whoever denies me before men, I also will deny before my Father who is in heaven” (Matthew 10:32-33). There are no secret disciples. Baptism is how a believer steps from the crowd into the spotlight, from the world into the church, from one allegiance to another.

This is also part of why infant baptism so deeply confuses things, as we’ll see below: instead of marking the church off from the world, paedobaptism risks blurring the line.

A Believer’s Union With Christ
Death to sin and separation from the world both flow downstream from a deeper, more fundamental reality—the believer’s vital, spiritual union with Christ Himself. We are not merely commanded to imitate Christ from the outside; we are joined to Him from the inside (Romans 6:5; Galatians 2:20; Ephesians 1:3-14; Colossians 3:1-4). This union is the engine that drives every other benefit of salvation, and baptism is the ordained sign that affirms and portrays it.

This union is central to the meaning of baptism, as Paul explains in Romans 6:3-4 and Galatians 3:27. Baptism signifies that someone has turned from sin and been united to Christ by faith. We who were once “dead in our trespasses” have been “made alive together with Christ … raised up with him and seated with him in the heavenly places” (Ephesians 2:5-6). The verbs are emphatic—aorist, completed, definitive, ours by grace.[13]

Colossians 2:11-12 deserves a closer look here, because Paul makes a striking move: 11 “In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.” Notice the order. Paul does not say baptism is the new-covenant counterpart of circumcision. He says regeneration—“a circumcision made without hands … the circumcision of Christ”—is the new-covenant counterpart of circumcision, with water baptism functioning as the sign of that prior, internal, Spirit-wrought reality. Old covenant circumcision pictured the need for a circumcised heart (Deuteronomy 10:16; Jeremiah 4:4); new covenant baptism testifies that the heart has been circumcised, by faith, in union with Christ’s death and resurrection. The proportion is therefore: as circumcision was to regeneration in shadow, so water baptism is to regeneration in confessed reality. We will see in Section 2 why this typology is so important when paedobaptist arguments draw a tight typological line directly from circumcision to infant baptism—Paul himself draws the line differently.

The physical act of immersion dramatically pictures this union—being plunged under water represents dying and being buried with Christ, while being raised from the water represents resurrection to new life in Him. Baptism likewise signifies the benefits of this union: forgiveness of sins (Acts 2:38), cleansing from defilement (Acts 22:16; cf. Ezekiel 36:25-27), the indwelling Spirit and new life in Him (Romans 6:4; Titus 3:5-6), adoption into the household of God (Galatians 3:26-27; 4:4-7), incorporation into Christ’s body (1 Corinthians 12:13), and the sure hope of being glorified with Him on the last day (Romans 6:5; 8:17, 29-30; Colossians 3:3-4).

So baptism does not create union with Christ as an isolated act of water apart from Spirit-wrought faith; rather, it visibly portrays and publicly confirms the union Christ creates by grace through faith. The Spirit applies Christ to the believer by grace through faith, and the water makes that reality visible to the gathered church and the watching world. As the church says “Amen” over the candidate going under and rising up, heaven and earth alike see the gospel re-preached in living color.

A Believer’s Public Commitment To Christ And His Church
Inasmuch as baptism is a church’s act, it is also a believer’s act. A church baptizes; a Christian gets baptized. This passive posture matters: the believer does not baptize himself, because baptism is something received from Christ through His church, not something self-administered as a private act of spiritual expressions. And when the Christian goes under, two pledges are made—one to Christ and one to His people.

First, baptism is a believer’s public commitment to Christ. It is the first command Jesus gives a new disciple after repentance and faith (Matthew 28:19-20; Acts 2:38), and it is how that disciple “goes public.” In baptism, a believer takes Peter’s words and makes them his own: this is “an appeal to God for a good conscience, through the resurrection of Jesus Christ” (1 Peter 3:21). The Greek noun eperōtēma (“appeal”) carries both a petition asking God to save and a pledge of loyalty to the One who has saved. Baptism is therefore simultaneously a prayer—“Save me, Lord Jesus!”—and an oath—“I belong to You.” It is a pledge of allegiance to one Commander, an oath of allegiance to King Jesus, by which the believer openly declares before heaven, the church, and the watching world that he is now under new management. He has decided, publicly and irrevocably, to follow Jesus.

This public dimension is non-negotiable. Jesus deliberately designed it this way. In Matthew 10:32-33 He tied confession itself to public profession: 32 “So everyone who acknowledges me before men, I also will acknowledge before my Father who is in heaven, 33 but whoever denies me before men, I also will deny before my Father who is in heaven.” There are no secret disciples in the kingdom—and tellingly, the New Testament records no examples of private baptism either. Even what looks like the most “private” baptism in Acts—Philip baptizing the Ethiopian eunuch on a desert road (Acts 8:26-39)—is no exception. The eunuch had just heard Isaiah 53 publicly preached by Philip, his confession of faith was witnessed by Philip and his entourage, and the moment Philip departed, “he went on his way rejoicing” (Acts 8:39)—a verb suggesting open, observable joy as he carried this news home. He was not baptized in secret; he was baptized in the only public assembly available to him in that moment, with the explicit intention of returning home to bear public witness in Ethiopia.[14] Baptism is not the only way Christians confess Christ before others, but it is the first and appointed way—the entry-level act of public allegiance from which the whole Christian life of public allegiance flows. It is how faith goes on record. It is how a believer steps from the shadows into the light, where the world can see what side he’s on. Pastorally, this is one of the reasons we press believers not to delay baptism. If you lack the courage to confess Christ publicly among believers who are cheering you on, what makes you think you’ll have the courage to confess Him in a world that mocks you for it? Baptism is, among other things, the rehearsal ground for a lifetime of public allegiance. Jesus tied the two together: “everyone who acknowledges me before men, I also will acknowledge before my Father who is in heaven” (Matthew 10:32). The boldness required for the lifetime of confession that Jesus calls for begins—by His design—with the boldness required to step into the water in front of His people.

Second, baptism is a believer’s public commitment to Christ’s church. Look again at Pentecost: “So those who received his word were baptized, and there were added that day about three thousand souls” (Acts 2:41). Added to whom? To the 120 already gathered (Acts 1:15). Baptism didn’t just unite them to Christ; it added them to His people. There is no in-between zone where a believer is with Jesus but not with His people. To be united to Christ is to become a member of His body (1 Corinthians 12:12-13; Ephesians 1:22-23; Colossians 1:18; 1 Peter 2:9-10). To call God “Father” is to embrace His other children as brothers and sisters.

So in baptism, the believer says, “I hereby pledge myself to Christ—and to you, His people.” And the church, in turn, says, “We hereby affirm your profession—and pledge ourselves to you, a member of Christ’s body.” Two vows. One body. One Lord.

This twofold commitment is also why, as we’ll argue in Section 3, baptism is properly the front door of church membership—not a separate event from joining the local church but the very act by which one joins.

Before working through the specific arguments for and against infant baptism, one structural observation is worth naming. Behind the paedobaptist case lies a particular understanding of how God’s covenants work—an understanding that defines covenantal categories too narrowly along biological-family lines. Paedobaptism tends to import Old Testament patterns of physical descent (the offspring of Abraham, marked by circumcision) into the New Testament administration of the new covenant. This is why so much paedobaptist exegetical weight falls on the so-called “household baptisms” of Acts—the household is read as a biological covenant unit. But the New Testament defines covenantal categories spiritually: the family of God is composed of those born not of blood or of the will of the flesh but of God (John 1:12-13). As we will see below, households in Acts are not baptized because the head professes; they are baptized because the household itself responds in faith to the preached word. The pattern is household conversion followed by household baptism—never household baptism on the basis of household lineage. This single shift in covenantal frame—from biological-physical to spiritual-faith-based—drives most of the differences between credobaptism and paedobaptism that follow.

The Biblical Mandate—For All Christians
Baptism is for every Christian—no exceptions. After repenting and believing, baptism is the first command Jesus’ followers must obey. This is clear from both the Great Commission (Matthew 28:19-20) and Peter’s preaching at Pentecost (Acts 2:38).[15] Throughout the New Testament epistles, the writers assume all their Christian readers have been baptized (Romans 6:3-4; Galatians 3:27). There is no category of “unbaptized disciple” in Scripture. If you trust in Christ but haven’t been baptized, this needs to be your first step of obedience.

The Positive Case From The New Covenant
Before listing problems with paedobaptism (the practice of baptizing the infants of believers), it is worth seeing what is right about believer’s baptism positively. The new covenant promise itself is what makes the question turn out the way it does.

First, though, it’s worth naming the deeper interpretive question that drives the whole baptism debate. While the paedobaptist case for infant baptism rests on inference forward from the Old Testament into the New—chiefly from the Abrahamic Covenant’s inclusion of infants in the sign of circumcision, the credobaptist (‘believer’s baptism’) case, by contrast, rests on the New Testament’s own positive teaching about the new covenant and its sign. Behind most specific arguments lies this hermeneutical question: To what extent is the Old Testament determinative of how it is fulfilled in the New, or vice versa, the New Testament determinative of how it fulfills the Old? Credobaptist theologians who hold to a “progressive revelation” view of Bible interpretation have emphasized the latter—the New is the inspired commentary on the Old, the apostles are the authoritative interpreters of fulfillment, and Christ Himself is the lens through which all earlier types must be read (Luke 24:27, 44-47; John 5:39, 46; 2 Corinthians 1:20).[16] To run the typology in reverse—to read the Old Testament’s pattern over the New Testament’s prescription—is to put progressive revelation in reverse gear. This single hermeneutical principle, faithfully applied, substantially summarizes the case for credobaptism.

Jeremiah 31:31-34 is the hermeneutical key. There Yahweh contrasts the new covenant with the old: 31 “Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah, 32 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. 33 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. 34 And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”

Notice carefully what Yahweh promises. Under the old covenant, some had the law internalized; in the new, all will. Under the old, some knew the Lord savingly; in the new, all will. Under the old, some had their sins forgiven; in the new, all will. The very thing that makes the new covenant new is that it closes the gap between covenant-belonging and covenant-keeping. Hebrews 8:6-13 doubles down on this contrast as inaugurated reality in Christ. The new covenant community is, by design and by divine guarantee, a regenerate community.[17]

Baptism is the ordained sign of entrance into that community. Therefore the sign should only be administered to those who give credible evidence that the substance is theirs—who, by their profession of faith, give the church reason to believe that the new-covenant realities (the law on the heart, the knowledge of the Lord, the forgiveness of sins) have actually come true in their lives.

The Negative Case: Seven Theological Problems With Infant Baptism
While many churches practice paedobaptism, the practice lacks biblical warrant and creates seven theological problems:

(1) Paedobaptism applies the sign of regeneration to those not yet regenerated, confusing being born of Christian parents with being born again. Baptism is a sign of a believer’s union with Christ in His death, burial, and resurrection (Romans 6:3-4; Colossians 2:11-12; Galatians 3:27). Infants are not ordinarily known to be united to Christ by a credible profession of faith.[18] Even children born to believing parents must receive Christ by faith in order to be joined to Him by the Spirit (John 1:12-13; 3:3-8; Ephesians 2:1-9). The New Testament knows only one way a person is “made new”—being born again by the Spirit through the gospel (John 3:3-8; Titus 3:5; 1 Peter 1:23)—and natural birth into a Christian home is not it. Yet the very act of infant baptism proclaims, “This one is united to Christ, has been buried and raised with Him, has been forgiven and made new.” It applies the sign where the substance is not (yet) present, divorcing the symbol from what it symbolizes and effectively communicating that new birth is inheritable through natural birth—a confusion of physical lineage with supernatural regeneration.

(2) Paedobaptism mistakenly assumes that God forms His new covenant people the same way He formed His old covenant people. Under the old covenant, God propagated His people by familial descent—the physical offspring of Abraham, marked off from the nations by circumcision and the law. But under the new covenant, God is not propagating an ethnic community through familial descent. By His Spirit applying the gospel to hearts, He calls His people out of every tribe, tongue, and nation (Revelation 5:9-10; 7:9-10). The way into the new covenant people is no longer natural birth but spiritual rebirth (John 3:3, 5). So the sign of the new covenant should go to those who give credible evidence of that rebirth—not to infants who are merely born.

(3) Paedobaptism ultimately undermines the church’s saltiness and lightness (Matthew 5:13-16). God’s old-covenant people were, by design, a spiritually mixed multitude. The physical sign of circumcision came before, and with no guarantee of, the spiritual reality of a circumcised heart (Deuteronomy 10:16; Jeremiah 4:4). But this is precisely what God changes in the new covenant. By design, the new covenant people are all renewed, all forgiven, all indwelt by the Spirit. Yes, false professors do inevitably creep in—which is why Jesus instituted church discipline (Matthew 18:15-20; cf. 1 Corinthians 5)—but this is to be excised, not enshrined. However, by policy, paedobaptism brings into the church those who do not yet participate in new-covenant realities. Over time, and especially as false professors grow old, this risks dulling the church’s distinctive witness, making her salt less salty and her light less bright—because she is being filled, by design, with those who are not (yet) hers.

(4) Paedobaptism dissolves crucial differences between baptism and circumcision. Paedobaptists draw a tight typological line from circumcision to infant baptism. But Paul draws the line differently. In Colossians 2:11-12 he says Christians have already been “circumcised with a circumcision made without hands,” an internal, Spirit-wrought severing of the body of flesh—that is, the old sinful nature. Then, in the same breath, Paul mentions baptism as picturing this prior, internal reality. Circumcision pointed forward to regeneration; baptism testifies that regeneration has occurred. Circumcision marked Israel off as a distinct ethnic and political entity regardless of internal spiritual state; baptism marks off the regenerate as those who have already passed from death to life. The new-covenant fulfillment of circumcision is not the baptism of infants; it is the Spirit’s circumcision of the heart, which baptism then publicly attests in those who have received it.

(5) Paedobaptism turns the new covenant promise into an uncertain possibility. Acts 2:38-39 reads, 38 “And Peter said to them, ‘Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. 39 For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.’” Paedobaptist appeals often emphasize “your children,” but the sentence continues. The promise is offered to three groups in apposition[19]—“you,” “your children,” and “all who are far off”—and all three groups are then qualified by the same conditional: “as many as the Lord our God calls to himself.” The Greek syntax is unambiguous: “as many as the Lord our God calls to himself” governs the whole compound indirect object—not just the third category of “all who are far off.” This means that whatever the verse promises to “you” or “your children,” it equally promises to “all who are far off”—and no paedobaptist reads “all who are far off” as warrant for baptizing every distant Gentile sight unseen. The condition that bounds the promise is not parental status but the Lord’s effectual call (cf. Romans 9:6-8; 11:5). Then notice how Luke himself answers the question of who actually received the promise that day—verse 41 “those who received his word were baptized,” not ‘those who were related to those who received his word.’ Acts 2:39, far from grounding infant baptism, actually grounds the baptism of disciples alone. Once Acts 2:39 is read this way, the deeper theological problem with the paedobaptist appeal comes to view.

Therefore, when paedobaptists appeal to Acts 2:38-39—“the promise is for you and for your children”—as warrant for baptizing the children of believers, what promise is this, exactly? In context, it is the new-covenant promise of forgiveness, the indwelling Spirit, and the writing of the law on the heart (Acts 2:38; Jeremiah 31:31-34). Yet most paedobaptists candidly admit that many baptized infants never come to faith. Which means, under that system, “the promise” can be received in sign without ever being fulfilled in substance. That turns the promise, at least in practice, into a possibility rather than the guaranteed new-covenant reality Jeremiah describes. To maintain the practice, paedobaptism effectively requires a category Scripture never names: ‘in the new covenant, but not of it.’ This effectively rebuilds the very gap—covenant-belonging without covenant-keeping—that Jeremiah 31 says God Himself has destroyed. God’s new-covenant promise is more than a possibility; it is a guarantee. And the sign of that guarantee belongs only to those who give evidence that the substance is theirs.[20]

(6) Paedobaptism rests on a hermeneutic that, if applied consistently, would also overturn its proponents’ rejection of paedocommunion. Even the most respected paedobaptist scholars freely admit that the New Testament contains no command to baptize infants and no clear example of an infant being baptized. John Murray himself concedes this: “What by good and necessary inference can be deduced from Scripture is of authority in the church of God as well as what is expressly set down in Scripture. The evidence for infant baptism falls into the category of good and necessary inference.”[21] That is a stunning concession—the paedobaptist case is built not on what Scripture says about Christian baptism but on what Scripture is alleged to imply by inference from Old Testament practice. Yet most of these same paedobaptists reject paedocommunion—the inclusion of infants at the Lord’s Table—on the grounds that the New Testament positively requires self-examination before partaking (1 Corinthians 11:28). They cannot have it both ways. If New Testament positive precept (self-examination) is sufficient to bar infants from the Supper, then New Testament positive precept (“repent and be baptized,” Acts 2:38; “they who received his word were baptized,” Acts 2:41) is sufficient to bar them from baptism. Inferred Old Testament inclusion cannot overrule expressly instituted New Testament prescription—if not for one ordinance, then not for the other.

(7) Paedobaptism is internally inconsistent on its own premise—if children, why not grandchildren? Even granting the paedobaptist appeal to continuity with circumcision, modern paedobaptist practice doesn’t actually match the practice it claims to continue. Circumcision was administered intergenerationally—to “you and your offspring after you throughout their generations” (Genesis 17:9-12)—regardless of whether the immediate parents were faithful. Joshua 5:2-8 is decisive: when the wilderness generation was circumcised at Gilgal, no one examined the parents’ faith first. So consider: John Sr. is a devout believer; John Jr. has never professed faith; John III is one week old. By the logic of “continuity with circumcision,” John III should be baptized. The earliest Reformed paedobaptists agreed; Calvin himself argued that baptism’s promise “extends to thousands of generations” and applies to “an offspring descended from holy and pious ancestors, though their fathers and grandfathers may have been apostates.” Yet contemporary paedobaptism almost universally refuses to baptize John III—which means the criterion has quietly shifted from intergenerational descent (the circumcision pattern) to credible profession of faith (the credobaptist pattern). The argument from continuity with circumcision quietly collapses into the argument for believer’s baptism.[22]

The “Household Baptism” Objection
Paedobaptists frequently appeal to the so-called household baptisms of Acts to argue that whole families—including, presumably, infants—were baptized regardless of personal faith. But the texts themselves resist this reading. Acts 16:32 says Paul and Silas “spoke the word of the Lord to him and to all who were in his house”—meaning everyone present was old enough to be addressed by gospel preaching. Acts 16:34 says the jailer “rejoiced along with his entire household that he had believed in God”—the whole household believed, not just the head. Acts 18:8 says of Crispus that he “believed in the Lord, together with his entire household.” 1 Corinthians 1:16 mentions Paul baptizing the household of Stephanas; 1 Corinthians 16:15 then describes that same household as “the firstfruits of Achaia [who] have devoted themselves to the service of the saints”—a description of mature Christian discipleship, not of infant beneficiaries. Cornelius’s household is even more decisive. Acts 10:44-48 records that “the Holy Spirit fell on all who heard the word” before any baptism took place, and Peter explicitly grounds his decision to baptize on this evidence: “Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?” The criterion for baptism in the household was not familial inclusion but Spirit-given response to the word—a criterion no infant could meet. Acts 8:12 likewise says of Samaria, “they were baptized, both men and women” (notably, not “men, women, and children”). The household baptisms were household conversions triggered by faith as response to the preached Word. There is no example anywhere in Scripture of a non-believing infant being baptized.[23]

Conclusion
Despite the noble intentions of paedobaptist Christians and the genuine theological care many bring to their position, infant baptism applies the sign of the new covenant to those who do not yet participate in the new covenant. It puts the cart before the horse: a sign of regeneration on those who have not yet been regenerated, a sign of faith on those who do not yet (and may never) believe. As we’ll see in the next section, baptism signifies new-covenant realities that are only true of believers, not infants.

So if you were “baptized” as an infant, you have not yet been baptized in the New Testament sense. You still need to be—for the first time.

Having established the proper subjects of baptism, we now turn to baptism’s relationship to formal church membership.

Baptism’s necessity for joining a local church is one of the most contested questions in evangelicalism today. Many Christians take it for granted that any church should welcome any Christian into membership, regardless of whether that Christian’s understanding of baptism matches the church’s. So why should an otherwise faithful, godly, gospel-loving paedobaptist Christian be denied membership at a church holding to credobaptism? Or, why should a Christian who simply hasn’t gotten around to being baptized be denied membership? Isn’t a credible profession of faith enough?

The short answer is no, and not because we are imposing some extrabiblical hoop on top of the gospel. Baptism is the divinely appointed form of a credible profession of faith—the public, ecclesial act by which faith becomes recognizable in the church and in the world. To require baptism for membership is not adding to the gospel; it is refusing to subtract from Jesus’ own model and design.

The Biblical Case
There is no single proof-text for this position; the case is built cumulatively from what Scripture teaches about baptism, the new covenant, the kingdom, and the church. Here are seven reasons, taken together, that make the case decisive:

(1) Baptism is where faith goes public. The Christian life is a life of open witness to Christ (Matthew 10:32-33), and that life begins at baptism. At Pentecost, those converted by Peter’s preaching stepped out of the crowd and submitted to baptism (Acts 2:38-41). They went on the record. They came out of hiding. In baptism a believer “outs” himself as a Christian, publicly identifying with the crucified and risen Christ and with His people. So when Jesus commanded His disciples to make disciples by “baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded” (Matthew 28:19-20), He gave us baptism as the first command a new convert obeys. Baptism is where invisible faith first becomes visible. It is how a new Christian shows up on the church’s radar—and the world’s. Every reason that follows grows from this seed.

(2) Baptism is the initiating oath-sign of the new covenant. Through His death, Jesus inaugurated the promised new covenant (Jeremiah 31:31-34; Luke 22:20; Hebrews 8:6-13; 9:15). Every covenant in Scripture is ratified by an oath—a solemn, self-obligating promise—and that oath is often signified by an act. When God made a covenant with Abraham, He passed between the halves of slaughtered animals (Genesis 15:9-21). When the old covenant was renewed at Sinai, it was sealed in sacrificial blood (Exodus 24:5-8). The new covenant likewise comes with an oath-sign—actually two: baptism, the initiating oath-sign, and the Lord’s Supper, the renewing oath-sign.[24] In baptism a believer swears the covenant oath, “appealing to God for a good conscience through the resurrection of Jesus Christ” (1 Peter 3:21), receiving from the Father, Son, and Spirit the covenant name they bear (Matthew 28:19), and pledging by grace to fulfill all that the new covenant requires. Just as a soldier cannot take up arms before swearing allegiance, a believer cannot enter the fellowship of the new covenant community without performing its initiating oath-sign.

(3) Baptism is the passport of the kingdom and the kingdom citizen’s swearing-in ceremony. When Jesus inaugurated the kingdom of heaven on earth, He established the church as an embassy of that kingdom and gave her the “keys of the kingdom” to identify her citizens (Matthew 16:19; 18:18-19). The first means by which a church identifies an individual as a kingdom citizen is baptism (Matthew 28:19). Baptism is how a church declares, “This one belongs to Jesus.” It is the passport by which other gospel churches recognize the same person as a fellow citizen and the swearing-in ceremony by which a new citizen formally takes up his or her office of representing the King and His kingdom on earth. To recognize someone as a kingdom citizen, a church needs to see the passport. No passport, no recognition; no recognition, no membership.

(4) Baptism is a necessary criterion by which a church recognizes who is a Christian. This follows directly from the previous three points. Because baptism is how a church publicly identifies someone as a Christian, baptism is a necessary—though not sufficient—criterion by which the church is to recognize Christians at all. It is not enough that someone claims to be a Christian, or even that the whole church is persuaded he is one. Jesus has bound the church’s judgment to baptism. He gave us baptism, in part, so that we could tell each other apart from the watching world. Scripture itself binds the church’s recognition of Christians to baptism in this way. The Great Commission gives the church one composite task—make disciples, baptize them, and teach them (Matthew 28:19-20)—with no provision for recognizing as a disciple anyone who refuses the second step. At Pentecost, those who received Peter’s word were baptized, and only the baptized are then said to be “added” to the gathered three thousand (Acts 2:41). The whole flow of Acts assumes the same: the Samaritan converts are baptized (Acts 8:12); Saul is baptized (Acts 9:18); Cornelius’s household is baptized (Acts 10:47-48); Lydia is baptized (Acts 16:15); the Philippian jailer is baptized (Acts 16:33); the Corinthians who believe are baptized (Acts 18:8); the Ephesian disciples are baptized (Acts 19:5). In every case the church identifies new Christians by baptism, and the apostolic letters subsequently address those churches as bodies whose members are uniformly assumed to have been baptized (Romans 6:3-4; 1 Corinthians 12:13; Galatians 3:27; Ephesians 4:5; Colossians 2:12). There is no example anywhere in the New Testament of a church formally recognizing as a Christian someone who refused or neglected this step. Christians wear the team jersey; non-Christians don’t. A church that recognizes someone as a member of Jesus’ team before that person has put on the jersey is making a recognition Jesus did not authorize.

(5) Baptism is an effective sign of church membership. If baptism is where faith goes public, the initiating oath-sign of the new covenant, the passport of the kingdom, and a kingdom citizen’s swearing-in ceremony, then baptism is not merely a precursor to church membership—it is the act that creates the churchly reality it signifies. If membership is a house, baptism is the front door. By stepping through the front door, you enter the house. For a new convert, baptism is the New Testament way to join a church. So we should not picture baptism on one side and membership on the other, with a delay, class, or vote inserted between them; Scripture nowhere prescribes such a separation, and the New Testament pattern actively resists it (Acts 2:41; 8:12; 10:47-48; 16:14-15, 33; 18:8). Normally, baptism publicly confers membership; the two belong together as one ecclesial movement. Paul makes the same logic explicit in 1 Corinthians 12:13: “For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit.” Baptism is the entry-act of incorporation into the body. To be baptized is, by Christ’s own design, to be brought into His people; to be brought into His people is, in any local expression, to be made a member of a particular church. The “house” and the “front door” are not two separate buildings.

(6) The Lord’s Supper, the other ordinance, requires baptism first. As noted above, the new covenant has two oath-signs. Baptism is its initiating oath-sign; the Lord’s Supper is its renewing oath-sign. When the church partakes of the bread and the cup, she renews her commitment to Christ and to one another in covenantal bonds (1 Corinthians 10:16-17; 11:23-29). To eat at this Table is to confess the gospel and to confess each other as the church—“because there is one bread, we who are many are one body” (1 Corinthians 10:17). It follows that no one can take part in the renewing oath-sign of the new covenant who has not yet performed its initiating oath-sign. You cannot sit at the family meal until you have come through the family door.

(7) Without baptism, membership doesn’t actually exist. What does all this add up to? Simply this: church membership is not a freestanding institutional category we can grant on whatever terms we like. “Membership” is a theological term for the covenantal relation between a Christian and a church—a relation the ordinances both express and create. Baptism and the Lord’s Supper ratify this relation.[25] To speak of church membership without baptism is like speaking of marriage without vows. Marriage is a covenantal relation brought into being by vows; membership is a covenantal relation brought into being by the oath-signs of baptism and the Lord’s Supper. You cannot have the relation without the act that constitutes it. Therefore, you cannot have membership without baptism. Period.

Scripture’s pattern reinforces this. Acts repeatedly ties belonging-to-a-church directly to baptism: the three thousand at Pentecost are baptized and added—added to whom?—to the gathered 120 (Acts 1:15; 2:41). The unbaptized in Acts are never described as members of any local body; the baptized always are. Paul addresses entire churches as the baptized (Romans 6:3-4; 1 Corinthians 12:13; Galatians 3:27; Colossians 2:11-12)—not as a happy coincidence but because in his thought-world, “the church at Corinth” and “those who have been baptized into Christ at Corinth” name the same set of people. Conversely, the act by which a member is removed from the church is exclusion from the Lord’s Table (1 Corinthians 5:11-13), the renewing oath-sign of the covenant. The two ordinances bookend church membership: baptism brings one in; refusing to receive the Supper from a disciplined member shuts one out. Strip the ordinances away, and “membership” becomes a category Scripture does not describe and cannot sustain.

Addressing The Main Objection
The most common objection to this position runs something like this: “But this requirement excludes from membership genuine, godly Christians—particularly paedobaptists who sincerely believe their infant baptism was biblical baptism. Surely a church shouldn’t exclude from membership someone they’re confident is a Christian?”

To ask a church to recognize as baptism what it believes Christ has not authorized is not a request for generosity; it is a request that the church loosen where it believes Christ has bound. That would bind the church’s conscience in the name of freeing the applicant’s conscience. Christian charity—as would be Scripturally warranted for individual relationships—cannot require a church to make an ecclesial judgment it believes Scripture forbids.[26]

It might help to think of it this way: the airport gate agent is not doubting your sincerity when she asks to see your boarding pass. She is simply not authorized to seat you without the appointed sign that identifies you as a passenger. Likewise, the church is not denying that a paedobaptist may be a genuine Christian; it is saying that Christ has given baptism as the public form by which profession becomes ecclesially recognizable. As John L. Dagg put it, profession is the substance of church membership, and baptism is the form of profession—but Christ’s command requires the form as well as the substance.[27]

It is genuinely painful to deny formal membership to a beloved, fruit-bearing paedobaptist Christian. We feel that pain acutely. But it should be more painful still to revise the role Christ has assigned to baptism, to soften one of His commands into a suggestion, to undermine His authority over His own church, and to invite a faithful but mistaken Christian to remain uncorrected in what we believe Scripture identifies as disobedience, while the church publicly endorses it. The kindest, most honest, and most pastoral course is to lovingly press the biblical case for believer’s baptism—and then to receive into joyful membership all who, by God’s grace, come through the front door Christ Himself has opened.

It is worth adding one further consideration. Many of the scholars our paedobaptist friends most respect—Murray, Berkhof, Boston, Baxter, Bannerman—either explicitly state or substantially grant that there is no positive command to baptize infants and no clear example of one being baptized in the New Testament.[28] They hold their position, by their own admission, on inferred parallels with Old Testament circumcision. So when a Baptist church declines to receive an unbaptized paedobaptist into membership, the church is not pitting its conviction against an explicit New Testament practice they hold dear; it is pitting the New Testament’s positive prescriptions for baptism against an inference even their own scholars admit is only an inference. That is not narrowness; it is fidelity to what is “expressly set down or necessarily contained in the Holy Scripture” (1689 LBC 1.6).[29]

To say what something is, you also have to say what it isn’t. Having defined baptism positively in the sections above, we now need to identify the most common scenarios in which what Christians are calling “baptism” turns out, on closer inspection, not to be baptism at all. This matters for two reasons. First, some readers who think they have already been baptized may need to ask whether they actually have. Second, church leaders inevitably must make judgment calls about whether an incoming member’s “baptism” qualifies. Five scenarios are the most common candidates for disqualification.

Infant “Baptism”
As established at length in Section 2, infant baptism is not actually baptism. However well-intentioned the parents and pastors who practice it, and however sophisticated the covenantal rationale offered for it, the New Testament simply does not authorize the church to baptize the infant children of believers—nor did the first Christians practice it.[30] Baptism is the sign that the gospel has taken effect in someone’s life—that this person has died to sin, been united to Christ by faith, and been raised to walk in newness of life. This is where Colossians 2:11-12 matters again: Paul does not make infant baptism the new-covenant equivalent of circumcision; he makes the Spirit’s “circumcision made without hands” the fulfilled reality, with baptism publicly portraying that internal work in those raised with Christ “through faith.” Infants, including the infant children of believers, are not ordinarily known by the church to be united to Christ by faith. They have to be born again by the Spirit through the gospel just like everyone else. Infant “baptism” therefore applies the sign where the substance is not (yet) present, divorcing the symbol from what it is supposed to symbolize.

The practical implication is direct, however uncomfortable: if you were “baptized” as an infant, you have not yet been baptized in the New Testament sense. You still need to be—for the first time. This is not a slight against your parents or the church that performed the rite; honoring those who raised you in the faith is itself a Christian duty (Ephesians 6:1-3). But Christ’s authority outranks every other (Luke 14:26), and He has bound your obedience to His own appointed sign.

This is also why the issue should not be reduced to mode. Many people hear “your infant baptism was not baptism” as if the problem was that they were not immersed, but the deeper problem is subject before mode. Even if you were fully immersed as an infant, and it had been performed with deep covenantal seriousness, the New Testament problem would remain: you were still not a proper subject of biblical baptism at the time because you were not yet a believer. The person receiving the sign was not yet making a credible profession of faith. The question is not merely, “Was enough water used?” but, “Was the right person being baptized for the right biblical reason?”

Infant “Baptism” Followed By Later Profession or Confirmation
A second, particularly common variation deserves its own treatment, because it is the practical reality for many Christians coming from paedobaptist traditions: infant baptism followed, years later, by a personal public profession of faith—often called “confirmation” in Roman Catholic, Lutheran, Anglican/Episcopalian, and some Reformed contexts, or simply “profession of faith” in Reformed and Presbyterian traditions.

The objection runs something like this: “Yes, I was baptized as an infant, but I later professed faith for myself at confirmation when I was 13. So I actually have both the sign and the profession. Why should I be baptized again?”

The question is sincere and the underlying intuition is correct—personal profession of faith is essential to baptism. But the conclusion is mistaken, for three reasons.

First, confirmation is not baptism, biblically speaking. No paedobaptist tradition claims that it is. Confirmation is variously understood as the completion of initiation, the personal owning of baptismal vows, or a separate rite admitting one to the Lord’s Table—but in none of these traditions is confirmation itself called baptism, performed with water, or substituted for baptism. Confirmation and baptism are two distinct rites in the paedobaptist sequence, not one combined act. So at no point in the paedobaptist sequence has the believer received what the New Testament calls baptism: the application of water, by the church, to a person making a credible profession of personal faith.

Second, the order matters more than it may appear. The New Testament pattern is uniform and irreversible: profession of faith first, baptism as the public sign of that profession. The Great Commission says, “make disciples … baptizing them” (Matthew 28:19)—disciples first, baptism after. The apostles’ pattern in Acts is the same: profession first, immediate baptism (Acts 2:38-41; 8:36-38; 16:14-15, 31-33; 18:8). Confirmation-after-infant-baptism reverses this order—sign first, profession years later. But the sign is meant to be the public visible attestation of an internal reality already wrought by faith; it cannot meaningfully attest a faith that does not yet exist. A sign administered in advance of the reality it signifies is a sign disconnected from its substance.

Third, the two acts cannot be summed. This is the most important point. Adding a profession-without-water (confirmation) to a water-without-profession (infant baptism) does not produce New Testament baptism, because New Testament baptism is not the sum of those two parts but the single, unified act in which they coincide. The water and the profession must occur together, in the believer’s own act of public allegiance, for what happens to be baptism in the New Testament sense.

So if your story is “infant baptism plus later confirmation or profession of faith,” the practical implication is the same as in the simpler infant-baptism case: you have not yet been baptized in the New Testament sense, and you should be. This is not a denial that you are a Christian; the very fact that you made a credible profession at confirmation may well be evidence that you are. It is a recognition that the sign of being a Christian has never yet been administered to you in the way Christ appointed it.

Pastorally, we recognize that this can feel like an even harder ask than the simpler case. Confirmation is often a meaningful, intentional act, taken seriously by you and by those who walked with you through it. We honor that. But the question is not whether confirmation was meaningful; the question is whether it was baptism. What the New Testament asks of you is not less than what you received at confirmation—a public profession of faith—but more: the same profession, made publicly in the act of baptism itself, where the water and the word coincide as Christ designed them to.

If this is your situation, please do not try to sort it out alone. Talk with one of our elders or staff. We have walked many faithful Christians from paedobaptist backgrounds through this same conversation, and we would consider it a joy to walk with you.

Non-Believer “Baptism”
A third scenario is more common than many realize: a person submits to baptism as a teenager or young adult under the impression that he is making a profession of faith, but later realizes that, in fact, he was not converted at all at the time. Maybe the youth group covered baptism and “everyone else was doing it” so he went along. Maybe he was responding to peer pressure or family expectation rather than to the work of the Spirit. Maybe he simply mistook religious feelings for saving faith. Years later, having actually trusted Christ, he wonders: “Was I really baptized? Should I be baptized again?”

Strictly speaking, the answer is no—he should not be baptized again. He should be baptized for the first time. Baptism is intended for believers. If you were not a true believer when you went under the water, then what happened was a dunking, not a baptism. The water touched skin but did not confirm a real, Spirit-wrought union with Christ, because there was no such union yet. Once you have come to genuine faith, you should obey Christ’s command and be baptized in earnest. This is not a “second baptism”; you have not yet had a first.

But there is also a messier case that requires more pastoral care. Consider someone who was raised in a Christian home, professed faith and was baptized as a child of six or seven, walked through normal developmental ups and downs as a teenager (some seasons of doubt, some seasons of immaturity, some seasons of mixed fruit), and now in young adulthood wonders whether her childhood profession was real. Should she be baptized again, “just to be sure”? Almost always, no. Baptism is meant to be performed once and not repeated over mere doubts. The wise course in such cases is to look for evidence of regenerate life across the long arc—not perfection, but direction. Does the person know and love Christ? Has she persisted, with God’s grace, in the faith? Has she ever explicitly renounced Christ or lived in unrepentant, public sin to which she was committed? If the long-term evidence points to a real, if undramatic, conversion in childhood, then she should rest in her childhood baptism and press on. The criterion for re-baptism is not lingering uncertainty about feelings; it is positive conviction that one was not a believer at the time. Such judgments should never be made alone; godly pastors and elders should be involved in walking through them.

Gospel-Denying Church “Baptism”
A fourth scenario involves baptisms performed by churches that deny the gospel—either explicitly (by teaching another Jesus, another spirit, or another gospel; see 2 Corinthians 11:4 and Galatians 1:6-9) or implicitly (by elevating baptism itself to the place of the gospel, treating the rite as that which forgives sins, regenerates the soul, and saves the recipient apart from repentance and faith). Baptism is an emblem of the gospel. To be baptized is to be identified with Jesus’ saving work. So a body that has effectively departed from the gospel does not actually have authorization from Christ to baptize people in His name—because, on that crucial point, it is not really a church at all.

To be clear: no church has perfect doctrine, and no preacher is infallible. We are not saying that baptism is only valid if the baptizing church is doctrinally pristine. We are saying that the same gospel which gives birth to a true church in the first place is what gives that church authority to baptize and the rite itself its meaning. Where the gospel is denied or replaced, “baptism” loses both its authority and its meaning. If you suspect the church that baptized you may fall into this category, do not try to sort it out alone. Bring the question to the leaders of a faithful, gospel-preaching church and let them help you weigh it carefully.

No-Church “Baptism”
A fifth and final scenario: a baptism performed with no real connection to a local church at all. Imagine two Christian friends in a backyard pool. One says, “Hey, you’ve never been baptized—want me to do it now?” The other says, “Sure!” The friend dunks him under and pronounces the Trinitarian formula. Has a baptism happened?

In ordinary circumstances, no. Baptism is a two-party act. It involves not just the believer’s commitment but also the church’s affirmation, and there is no sense in which the friend in the backyard is acting on behalf of a gathered local church. The keys-of-the-kingdom authority Jesus gave was given not to individuals as individuals, but to local churches and those they authorize (Matthew 16:19; 18:18-20; 28:18-20). So in a context where churches exist and are accessible, a baptism with no connection to a church is not baptism. The new convert should be brought to the gathered church and baptized there, under proper authority, into membership.

The one legitimate exception is the genuine frontier missionary situation. Where no local church yet exists in a given place, whoever brings the gospel can—and should—baptize those who respond to it. The first convert is not “baptized into a church” because there is no church yet; the first convert is baptized into Christ, and as soon as one or two more come to faith, those baptized believers should covenant together to become a church which will then oversee future baptisms. This is the pattern Acts itself depicts. But this exception is narrow, and it should not be invoked to justify ecclesial sloppiness in well-churched places or convenient swimming pools.

Conviction, Conscience, And A Church’s Responsibility
A closing word is in order before we move from theology to practice. Everything in this section has assumed that the question of what counts as biblical baptism is one the church must answer with theological care—and that the answer will sometimes be uncomfortable for the people it touches. Three considerations frame how the church and the individual believer should each handle that discomfort.

First, a church cannot, in good conscience, be expected to act against its convictions on what Scripture teaches about baptism. This is true of any church, including paedobaptist churches, who would not (and should not) be expected to administer believer’s baptism to infants in violation of their convictions. The same courtesy must run in the other direction. A credobaptist church that has weighed Scripture, examined the historic confessions, considered the best paedobaptist arguments, and arrived at the conviction that infant baptism is not biblical baptism cannot reasonably be asked to suspend that conviction for the sake of welcome or convenience. To do so would be to ask the church to do what no faithful Christian should do—to teach as truth what it believes Scripture teaches otherwise, or to act as if Christ’s commands are negotiable when His commands are not.

Second, no Christian is exempt from the duty to think biblically about baptism for himself or herself. It is not enough to have inherited a tradition and accepted it because it was inherited. Every Christian is called to “test everything; hold fast what is good” (1 Thessalonians 5:21), to be like the Bereans, who were “more noble than those in Thessalonica” because “they received the word with all eagerness, examining the Scriptures daily to see if these things were so” (Acts 17:11), and to “always be prepared to make a defense to anyone who asks you for a reason for the hope that is in you” (1 Peter 3:15). Inherited tradition is not a substitute for inherited Scripture. If your baptismal practice cannot be defended from the Bible itself—not from family heritage, not from denominational loyalty, not from cultural Christianity, not from emotional attachment to the place or moment—then the right response is not to defend the practice but to reconsider it under the authority of the Word that the practice claims to obey.

Third, the goal of this section has never been to wound but to clarify. If you have read this section and realized that what you received was not biblical baptism, that realization is not a verdict on your salvation, your sincerity, or the godliness of those who raised you. It is an invitation: an invitation to come to clear conviction about what Scripture teaches, to talk it through with elders who would consider it a joy to walk with you, and—if conviction lands where Scripture seems to lead—to obey Christ in this matter for the first time, joyfully and publicly, before His gathered people. The aim of biblical clarity is never condemnation; it is conformity to Christ. And conformity to Christ on the question of baptism, like every other point of obedience, is meant to deepen joy, not diminish it.

The previous four sections have established baptism’s meaning, its subjects, its relation to church membership, and the limits of what counts as baptism at all. This section shifts gears from theology to practice. Five practical questions remain to be answered for any church that wants to practice baptism faithfully: How should we baptize—the mode? Who should perform the baptism—the administrator? How does baptism connect to formal church membership? In what setting should baptisms occur—the context? And when should a new convert be baptized—the timing? Each of these is a downstream question—the answers flow from what we have already established—but each requires a moment of focused practical reflection.

The Mode
As established in Section 1, the New Testament knows only one mode of the physical act of baptism: immersion. The Greek verb baptizō means to plunge or submerge, and the clearest New Testament narratives depict movement into and out of water (Mark 1:9-10; John 3:23; Acts 8:38-39). Immersion alone captures the symbolism of being buried and raised with Christ (Romans 6:1-4; Colossians 2:11-12). For these reasons, churches should baptize by immersion and resist any cultural pressure—or pastoral convenience—to substitute sprinkling or pouring.

Practically, this requires a church to provide a place suitable for immersion. Most churches build or install an indoor baptistry; others rent a portable pool, use a member’s swimming pool, or travel to a nearby river, lake, or creek. Any of these work. What matters is that the candidate be fully submerged and visibly raised—because the act itself is part of the message. The one element worth thinking through pastorally: water temperature, candidate dignity (suitable changing space, appropriate clothing for both men and women), and visibility for the gathered church. Practical wisdom in arranging these details serves the meaning of the act rather than distracting from it.

The Administrator
As established in Section 1, because baptism is an act of the church, its administrator should be authorized by the church—and because baptism is something received from Christ through His church rather than something self-administered, a believer does not baptize himself. The New Testament’s pattern bears this out: every recorded baptism is performed by someone exercising recognized teaching, apostolic, or evangelistic authority on behalf of the gathering church. John the Baptist baptizes under prophetic commission (Matthew 3:1-6; John 1:33); the apostles baptize under direct commissioning from the risen Christ (Matthew 28:18-20; John 4:1-2; Acts 2:38-41); Philip the evangelist baptizes the Samaritans and the Ethiopian eunuch in the exercise of his recognized office (Acts 8:5, 12, 38; cf. Acts 21:8); Ananias is sent by Christ Himself to baptize Saul (Acts 9:10-18); Peter directs the baptism of Cornelius’s household (Acts 10:48); Paul baptizes those whom his evangelistic ministry brings to faith (Acts 16:15, 33; 18:8; 19:5; 1 Corinthians 1:14-17). In every case, the administrator stands in some recognized relation to the gathering or sending church and acts on its behalf.

The Great Commission itself was given to the gathered apostles as the foundation of the church (Matthew 28:18-20), and the keys-of-the-kingdom authority by which baptism is administered was given to the church corporately, not to individuals as individuals (Matthew 16:18-19; 18:18-20). While Scripture doesn’t absolutely require pastors to perform the baptism ceremony itself, it is wise to normalize their leadership of the process since they are the elders Christ has appointed to act on the church’s behalf in such matters (Acts 20:28; 1 Timothy 3:1-7; Titus 1:5-9; 1 Peter 5:1-4).

Individual Christians do not as such have authority to baptize simply by virtue of being Christians, but only insofar as they act under the church’s authority—which is why even when a non-elder performs a baptism (a parent baptizing a child, say, or a friend baptizing a friend), it should be done with the church’s knowledge, blessing, and presence, as an extension of the church’s authority rather than a freelance act apart from it. The only exception is frontier missionary situations discussed in Section 4, where no local church yet exists to authorize the baptism.

The Connection To Church Membership
As argued at length in Section 3, baptism normally confers church membership. It isn’t a prerequisite to membership; it is the act by which membership begins. Churches should therefore resist treating baptism and membership as unrelated acts, even where a short process of instruction, elder interview, or congregational affirmation precedes the baptism. The New Testament pattern is uniform: those who heard the gospel and believed were baptized, and the baptized were thereby “added” to the gathered church (Acts 2:41; cf. 8:12; 10:47-48; 16:15, 33; 18:8). The biblical pattern joins baptism and membership as one act of incorporating a believer into Christ’s body.

The only legitimate exception is the narrow case discussed in Section 4: when a new believer is baptized in a place where no local church yet exists (a frontier missionary situation, or a new convert immediately relocating to an unchurched area). In such cases, baptism unites the believer to Christ and to the universal church even when local-church membership must wait for one to be planted.

The Context
Because baptism is the church’s act of affirming a believer’s profession and welcoming the believer into membership, it should normally occur in the context of a gathered, whole-church assembly. This does not mean baptism must happen in a particular building or even during a Sunday morning service—a Sunday evening service, a midweek gathering, a church retreat, or an outdoor location can all work—but it does mean the gathered congregation should be present as a body, not merely a handful of friends and family. The body that affirms a believer’s profession must be present to do the affirming.

Private baptisms—performed with only a few witnesses or in family-only settings—should be the rare exception, not the rule. (The New Testament’s one apparent exception, the Ethiopian eunuch in Acts 8, was not actually a private baptism in our sense; it was the only public gathering available on a desert road, and the eunuch immediately carried his profession back to Ethiopia to make it public.) Baptism rehearses a lifetime of public confession; it should be performed publicly.

The Timing
The New Testament pattern is striking: baptism almost always follows profession of faith immediately—the same day, often within hours. The three thousand at Pentecost are baptized the day of their conversion (Acts 2:38-41). The Ethiopian eunuch is baptized within hours of hearing the gospel (Acts 8:35-38). The Philippian jailer is baptized “at once” the same night as his profession (Acts 16:33). Saul is baptized within days of his Damascus Road encounter (Acts 9:18). The apostolic instinct was clear: a believer who has trusted Christ should be baptized without delay.

In Western contexts today, two complications often slow this pattern. First, the gospel typically reaches people in cultures where Christianity is socially familiar but spiritually thin, which means new professions of faith are sometimes superficial and benefit from time to ripen into clarity. Second, many local churches now wisely tie baptism to a membership process that catechizes the new believer and gives the church time to know the candidate’s testimony. Both impulses can serve baptism’s meaning rather than undercut it. A two-, four-, or six-week interval between profession and baptism—during which the candidate receives clear teaching on what baptism means and is interviewed by elders—does not introduce a probationary period; it clarifies the meaning of the act and ensures both candidate and church know what they are affirming.

The line between wise delay and unwise delay is whether the delay serves baptism or substitutes for it. A delay that clarifies the gospel, confirms a credible profession, and welcomes the new believer into the formal life of the church is a healthy delay. A delay that drifts into months and years, or that effectively makes baptism conditional on attaining some advanced state of Christian maturity, betrays the New Testament pattern. The pastoral question for elders is always: are we serving baptism’s meaning, or are we burdening the believer with hurdles Christ never imposed?

A particularly contested case is the baptism of children raised in Christian homes. Some churches baptize as young as six or seven; others wait until the teen years; still others recommend waiting until the young person has lived independently of parental supervision. There is no biblical mandate setting a minimum age, but the New Testament pattern does require a credible profession from someone capable of giving one. The general principle: baptize as soon as the candidate’s profession of faith is credible to the church’s elders, but not before, and not on parental pressure or peer momentum.

We started this booklet with the conviction that the Christian life is inherently a churched life and that baptism is the inaugurating sign of that life. Five sections in, the picture is clearer. Baptism is a church’s act of immersing a believer in water whereby it affirms and portrays the believer’s death to sin, separation from the world, and union with and commitment to Christ and His church. That definition is not a clever construction but a careful synthesis of the New Testament’s own teaching, drawn from Christ’s Great Commission, the apostolic pattern in Acts, Paul’s theology of union with Christ, Peter’s appeal to the resurrection, and the new covenant’s sweeping promise that all its members will know the Lord (Matthew 28:18-20; Acts 2:38-41; Romans 6:3-4; Galatians 3:27; Colossians 2:11-12; 1 Peter 3:21; Jeremiah 31:31-34; Hebrews 8:10-12).

From that definition, the rest of the booklet’s case follows. Baptism is for disciples—those who have actually died to sin, been separated from the world, and been united to Christ by faith—not for infants who have not yet experienced the realities the sign portrays. Baptism is the ordained gateway into formal church membership, not an optional add-on. And baptism is bounded—not every act that bears the name is the thing itself. Infant baptism, non-believer baptism, gospel-denying-church baptism, and no-church baptism all fall short of what Scripture means by the word.

These convictions matter because they shape the church Jesus is building. They shape who is recognized as a Christian, who participates in the Lord’s Table, how the watching world identifies the people of God, and whether the line between church and world remains visible. They shape evangelism (Christ’s people preach the gospel to the unconverted, including the unconverted children of believers); worship (the gathered church is, by design, a regenerate community); and discipline (the church can only excise from its body those it has first formally received). The differences between believer’s baptism and paedobaptism are not academic. They are, in the long run, the differences between two visions of what the church is.

Two practical exhortations close this booklet. If you are a Christian who has not been baptized in the New Testament sense—whether because you were “baptized” as an infant, or because you have not yet obeyed Christ’s first command to His disciples, or because the baptism you received was performed by a church that did not preach the gospel—then your next step is clear. Contact the elders of a faithful gospel-preaching church and arrange to be baptized. You have nothing to lose and everything to gain by obeying Jesus on this point. If you are an elder or pastor, take care that your church practices baptism in ways that preserve and proclaim its full biblical meaning—not as a private rite, not as a delayed reward for spiritual maturity, not as an optional precursor to membership, and not for those who have not yet been brought from death to life. The visible church becomes less visible at exactly the rate at which her ordinances become detached from their meaning.

Christ has bound the visible life of His people to two simple acts: a meal and a bath. Through one of them He nourishes those who have already entered His covenant. Through the other He marks the entrance itself. May this booklet help every believer who reads it, and every church that practices its teaching, to honor that entrance for what it is—an act of allegiance to a King who deserves nothing less than open, public, unashamed confession by His people.
