The Reformation’s Unfinished Business
The Protestant Reformation of the sixteenth century was, in its origins, an attempt to reform the Roman Catholic Church from within. Martin Luther did not set out to found a new church. He set out to cleanse the old one. When it became clear that Rome would not be reformed — that it would instead condemn the gospel and burn those who preached it — the break became unavoidable. But a break from Rome, however necessary and courageous, does not automatically constitute a complete return to the New Testament. Men who have spent their entire lives in one system carry its assumptions with them even when they walk out of its door. The question is not whether the Reformers broke from Rome — they did, at enormous cost. The question is whether they broke from Rome completely.
The Baptists have always said: not completely. And nowhere is this more clearly visible than in the doctrine of infant baptism.
The magisterial Reformers — Luther, Calvin, Zwingli, Bucer, and their successors — retained the practice of baptising the infants of believing parents. They rejected Rome’s doctrine of baptismal regeneration (that baptism itself saves the infant), but they retained the practice itself, grounding it now in a covenantal argument: God’s covenant of grace includes believers and their children, as the Abrahamic covenant included Abraham and his seed, and as circumcision was given as the sign of that covenant to infant males. Baptism, on this view, is the New Testament counterpart to circumcision and should be administered to the infant children of the covenant.
This argument is found in the most eminent and otherwise faithful ministers of the Puritan era. Thomas Manton (1620–1677), clerk to the Westminster Assembly, chaplain to Oliver Cromwell, and one of the most learned preachers of his generation, held and defended infant baptism as a matter of covenantal necessity. The Westminster Confession of Faith, which he helped to produce and whose second edition he prefaced, codifies the position in Chapter 28. It is not a fringe view in Reformed circles. It is the confessional standard.
We acknowledge the genuine faith, deep learning, and great service of these men. The error of infant baptism does not unchurch them or nullify their work. But it is an error — an error with traceable roots in Rome, preserved by the Reformers’ incomplete departure from the Catholic sacramental system — and it must be examined honestly in the light of Scripture.
Where Infant Baptism Came From
The practice of infant baptism has no warrant in the New Testament. It cannot be demonstrated from a single passage of Scripture that any infant was ever baptised. The case for it rests entirely on inference and analogy — specifically, the analogy between circumcision and baptism, and the argument that the covenant household structure of the Old Testament carries over into the New.
Historically, the practice appears to have entered the church gradually from the late second and third centuries onward, driven partly by a developing sacramental theology — the idea that baptism itself effected spiritual regeneration — and partly by the pastoral concern for infants who died before they could make a profession of faith. If baptism saves, then unbaptised infants who die are lost. That conclusion was intolerable, and so the practice of baptising infants as an emergency measure in the face of death expanded over time into the standard practice of baptising all infants as a matter of covenantal inclusion.
Tertullian, writing around AD 200, actually argued against infant baptism — which itself demonstrates that it was not an established apostolic practice. Origen, writing slightly later, acknowledged that the church of his day practised it but attributed it to a tradition received from the apostles — a claim that cannot be verified from Scripture and that the silence of the New Testament makes extremely improbable. By the time of Augustine (354–430), infant baptism was near-universal in the visible church and was being defended with sophisticated theological arguments, including the claim that it washed away original sin.
This is the river the Reformers stepped into. They rightly rejected the Augustinian claim that baptism washes away original sin. But they did not step out of the river. They stayed in it, rerouting its flow through a covenantal channel rather than a sacramental one. The Baptists — and before them the Anabaptists, and before them the various dissenting bodies that Rome labelled heretics — stepped out of the river entirely and returned to the clear ground of the New Testament.
The Covenantal Argument: What It Claims
The paedobaptist argument in its most careful form runs as follows. God made a covenant of grace with Abraham, and the sign of that covenant was circumcision, administered to Abraham and to all the males of his household including infants (Genesis 17:9–14). This covenant of grace is the same covenant under which believers are saved today — it is not a different covenant but the same one, administered differently in different eras. Since the New Testament church is the continuation of the covenant community that began with Abraham, and since baptism is the New Testament equivalent of circumcision (the sign and seal of the covenant of grace), it follows that baptism should be administered to the infant children of believers, just as circumcision was administered to the infant males of Israel.
Paul’s statement in Colossians 2:11–12 is the central proof text: In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. The paedobaptist reads this as establishing a direct equivalence between circumcision and baptism, making baptism the new circumcision and therefore appropriate for infants.
Five Reasons the Covenantal Argument Fails
1. The New Covenant is expressly made with believers only. The Reformers were right that the Abrahamic covenant included both believers and their physical descendants. But the New Covenant, established in Christ’s blood, is explicitly different in this respect. Jeremiah’s prophecy of the New Covenant — quoted at length in Hebrews 8 — defines it as a covenant in which every member knows the Lord personally:
The Old Covenant included members who did not personally know the Lord — they were in the covenant by physical descent from Abraham. The New Covenant is different precisely at this point: they shall all know me. Every member of the New Covenant community is a regenerate believer. The sign of the New Covenant — baptism — belongs therefore to those who know the Lord, not to their physical infants.
2. Circumcision and baptism do not signify the same thing. The paedobaptist argument requires that baptism be the direct counterpart of circumcision — that it means the same thing and therefore belongs to the same recipients. But this is not what Scripture teaches. Circumcision was the sign of national membership in Israel, physical descent from Abraham, and the covenant obligations of the Mosaic law. Baptism is the sign of death to sin, resurrection to new life in Christ, and union with him by faith.
Romans 6 makes the meaning of baptism unmistakable: it is a picture of death and resurrection — the believer’s death to sin and new life in Christ. An infant who has not believed, repented, or died to sin cannot meaningfully receive a sign that pictures death to sin. To administer it to an infant is not to give the sign its new covenant meaning — it is to empty it of meaning entirely.
Furthermore, Paul in Colossians 2 does not say that baptism replaces circumcision. He says that believers have received a circumcision made without hands — that is, the circumcision of the heart, the cutting away of the old sinful nature by the Holy Spirit in regeneration. This spiritual circumcision is what baptism follows and pictures. The sequence in the text is: spiritual circumcision (regeneration) → baptism (the outward sign). Infants have not received the spiritual circumcision of regeneration — or if they have, they do not need baptism to signify what God has already done.
3. Every New Testament example of baptism follows faith and repentance. Without exception, in every recorded instance of baptism in the New Testament, the order is: hearing the gospel — believing — being baptised. There is not a single instance of infant baptism anywhere in the New Testament. This is not an argument from silence in the ordinary sense. The New Testament records the rapid expansion of the church across multiple cultures and countries, describes dozens of baptisms explicitly, and provides detailed instruction on the meaning and significance of baptism — and in all of this, not once is an infant baptised, not once is infant baptism commanded, and not once is it so much as mentioned.
The paedobaptist appeals to household baptisms (Lydia’s household, the Philippian jailer’s household) as evidence that infants were included. But this is speculation unsupported by the text. Acts 16:32 states that Paul spake unto him the word of the Lord, and to all that were in his house before the baptism. The word of the Lord was preached to all who were baptised — which is incompatible with the baptism of infants who cannot receive a word preached.
4. Christ’s own commission defines the order. The Great Commission given by the risen Lord in Matthew 28 establishes the sequence unambiguously:
The word translated teach in verse 19 is the Greek matheteusate — make disciples. The commission is to make disciples of all nations and then to baptise them. Discipleship precedes baptism. An infant cannot be a disciple. Mark’s record of the commission makes the condition explicit:
Believing is the prerequisite. Baptism follows faith. The two belong together in this order and no other.
5. The Reformers’ own principle condemns their practice. The Reformers championed the regulative principle of worship — the rule that only what God has commanded in his Word should be practiced in the church. They applied this principle against Rome’s traditions, ceremonies, and inventions. But the very same principle, consistently applied, condemns infant baptism — for there is no command in Scripture to baptise infants, no example of it being done, and no apostolic instruction to that effect. The Baptists did not invent the regulative principle. They simply applied it consistently where the Reformers would not.
Baptismal Regeneration: Where Error Becomes Heresy
There is a distinction that must be drawn carefully here, and it is a distinction of the greatest importance.
There are sincere, godly Christians in Presbyterian and Reformed churches who practise infant baptism as a covenantal sign. They believe it marks the child as a member of the visible covenant community, places the child under the obligations and promises of the covenant, and is an act of faith by believing parents dedicating their child to God. They do not believe the water saves the child. Many such people are genuinely regenerate, hold the doctrines of grace firmly, and preach the free and sovereign grace of God with power and faithfulness. Thomas Manton was such a man. John Calvin was such a man. We do not question their salvation or write them out of the family of God. We believe they were wrong on this point, and wrong in a way that has consequencecs — but it is an error within the family.
But there is another position that is not an error within the family. It is a departure from the gospel itself. That is the doctrine of baptismal regeneration — the teaching that the water of baptism, when applied to an infant, actually regenerates the child, washes away original sin, and incorporates the child into saving grace. This is the official doctrine of the Roman Catholic Church, the official doctrine of the Eastern Orthodox Church, and the position of a significant portion of Lutheranism. It is also the practical assumption of vast numbers of people in mainline Protestant churches who were baptised as infants, have never known regeneration, and yet regard themselves as Christians on the grounds of their infant baptism.
Baptismal regeneration is a works salvation. It teaches that a physical act performed by a human priest or minister upon a passive infant accomplishes what only the sovereign grace of God can accomplish. It puts the water in the place of the blood. It makes the font the instrument of regeneration that Scripture assigns to the Holy Spirit alone. It is, in its essence, no different in kind from any other system that tells a sinner he can be saved by something other than the finished work of Jesus Christ received by faith.
The water in John 3:5 has been the subject of much debate, but the contrast Christ draws is unmistakable: flesh produces flesh; Spirit produces spirit. Regeneration is the work of the Spirit of God, entirely beyond the power of any physical element to effect or convey. The water of baptism is an outward sign — precious and significant as a sign — but it is a sign, not the thing itself. When any system teaches that the sign produces the reality, it has done what every false gospel does: it has replaced the work of God with the work of man.
Note carefully what Titus 3:5 says: God saved us by the washing of regenerating and renewing of the Holy Ghost — not by the washing of water. The washing that saves is the Spirit’s inward work, not any outward ordinance. Peter makes the same point with equal clarity:
Peter here defines what baptism is and what it is not. It is not the putting away of the filth of the flesh — it is not a physical cleansing that effects spiritual salvation. It is the answer — the pledge, the declaration — of a good conscience toward God. It is a faith-response, an outward declaration of an inward reality already possessed. An infant has neither a good conscience toward God nor the faith to declare it. And the salvation it points to is grounded in the resurrection of Jesus Christ — the finished work of Calvary, received by faith.
What the Gospel Requires
The gospel is not a sacramental system. It is not administered through water, oil, bread, wine, or any other physical element. It is received through faith — and faith alone — in the Lord Jesus Christ, who suffered under Pontius Pilate, was crucified, dead, and buried, and rose again from the dead on the third day.
Christ suffered and died to accomplish what no ceremony, no priest, no sacrament, and no water could accomplish. He bore in his own body the full weight of his people’s sins, satisfied the justice of a holy God, and rose victorious from the grave as the declaration that the debt was paid in full. To add anything to this — to say that a sinner must also be baptised to be saved, or that baptism applied in infancy secures the child’s salvation — is to say that Christ’s death was not enough. It is to dishonour his finished work and to give to water the glory that belongs to blood.
Baptism: Its True Meaning and Proper Recipients
Baptism, rightly understood, is one of the most glorious ordinances Christ has given to his church. It is a public declaration, before God, angels, and men, that the believer has died with Christ and been raised with him to new life. It is the answer of a good conscience toward God — the outward confession of an inward faith. It is the believer’s public identification with the death, burial, and resurrection of the Lord Jesus Christ. It belongs, therefore, to those who have believed — and to them alone.
A person who is baptised as an infant and grows up in the church of God may, by the sovereign grace of God, be truly converted and truly saved. But their salvation does not come from their infant baptism. It comes from God’s free grace working faith in their heart. And when they are saved, the appropriate response — the response of every believer in the New Testament — is to confess Christ publicly in the waters of believer’s baptism. This is not rebaptism, as paedobaptists charge. What was done in infancy was not baptism in the New Testament sense at all.
The children of believing parents are precious. They are to be raised in the nurture and admonition of the Lord (Ephesians 6:4). They are to be taught the Scriptures from infancy (2 Timothy 3:15). They are to be brought to Christ, who said suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God (Mark 10:14). The covenant faithfulness of God reaches to the children of his people in ways that should encourage every Christian parent. But none of this is accomplished by pouring water on an unconscious infant and pronouncing a liturgical formula. It is accomplished by the sovereign grace of God working through the diligent, faithful, prayerful instruction of godly parents — and ultimately, by the new birth wrought by the Holy Spirit in God’s own time.
The new birth is not of blood — not by natural descent from a Christian family. It is not of the will of the flesh — not by any human decision, ceremony, or rite. It is not of the will of man — not by a priest or minister applying water. It is of God. This is the gospel. This is what baptism points to. And this is why baptism belongs to those in whom God has wrought this miracle — to those who have received him, to those who believe on his name.
