Yesterday we established that church membership cannot save. The thief on the cross had no church membership, no attendance record, no service history, and received paradise. Because the root of salvation is not what you do inside a religious community. It is what Christ did on the cross.
Today we examine the most theologically contested addition to the gospel in the history of the church, and the one that is held across the broadest spectrum of Christian traditions, from Rome to the most conservative evangelical denominations.
Baptism.
Specifically, the claim that baptism is necessary for salvation. That the new birth is completed, sealed, or effected through the act of water baptism. That the person who has genuinely repented and genuinely trusted in Christ but has not been baptized is either not yet fully saved, not yet fully certain of salvation, or in some meaningful sense incomplete in their standing before God.
This claim is held in various forms by Roman Catholics, Eastern Orthodox, many Lutherans, the Churches of Christ, numerous Pentecostal denominations, and a significant number of Anglican and Episcopal traditions. It is not a fringe position. It is one of the most widespread doctrinal commitments in global Christianity.
And it is not in Paul’s four sentences.
Paul’s Most Direct Statement on the Subject
Paul had a baptism problem in the church at Corinth. Different factions were aligning themselves with the leaders who had baptized them, claiming a special spiritual status on the basis of who performed their baptism. Paul’s response is one of the most theologically decisive statements in the New Testament on the relationship between baptism and the gospel: “For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect” (1 Corinthians 1:17).
Christ sent me not to baptize, but to preach the gospel. Paul does not say baptism is unimportant. He does not say it should be abandoned. He has, in fact, baptized some of the Corinthians himself, he acknowledges this in the preceding verses. His point is not that baptism is worthless. His point is that baptism is not the gospel.
The separation is explicit. The commission Paul received was to preach the gospel, not to baptize. If baptism were part of the gospel, if it were a condition of salvation that needed to be applied to complete the saving work, then the commission to preach the gospel would necessarily include the commission to baptize. But Paul separates them. Deliberately. Because they are separable. Because the gospel can be complete without baptism in a way it cannot be complete without the death, burial, and resurrection of Christ.
Furthermore, Paul says that adding human wisdom to the preaching of the gospel would make the cross of Christ of none effect. The cross is the thing that must not be neutralized. And adding baptism as a condition of salvation, making the completed work of Christ incomplete without the application of water by a human minister, is precisely the kind of addition that makes the cross of none effect. It says: what Christ accomplished was not enough on its own.
The Thief on the Cross — Again
Yesterday the thief refuted church membership as a condition of salvation. Today he refutes baptism. The thief on the cross was a condemned criminal in the final hours of his life. He had no opportunity to be baptized after his conversion. He had no church, no minister, no water. He turned to Christ in the last possible moment and received the most unambiguous promise of paradise recorded in the Gospels.
If baptism were necessary for salvation, if the new birth required water to be complete, then the thief was not saved. He died on the cross next to Jesus without fulfilling the necessary condition. Not, you would be with me in paradise if only there were time to baptize you. Not, you are forgiven but your standing is uncertain until the sacrament is applied. Saved, because faith alone in Christ alone was sufficient.
Every theological system that requires baptism for salvation has a thief problem. And the thief problem cannot be resolved without contradicting the explicit words of Christ.
What About “Baptism Doth Also Now Save Us”?
The primary proof text used to support baptismal regeneration is 1 Peter 3:21 — “the like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ.” This verse is frequently cited as the clearest biblical statement that baptism saves. And on a surface reading, baptism doth also now save us, it appears to support the claim.
But read the whole verse. Peter himself provides the interpretation of what he means, in the parenthetical qualification that follows immediately: not the putting away of the filth of the flesh. Peter explicitly says that the baptism he is talking about does NOT refer to the physical act of washing. It is not water doing a physical work.
What then does it refer to? The answer of a good conscience toward God. The Greek word translated answer is eperotema, a pledge, an appeal, a commitment. Baptism, as Peter describes it here, is the outward pledge of the inward commitment, the public declaration of the repentance and faith that have already taken place.
The baptism that saves, on Peter’s own account, is not the water applied to the body. It is the reality the water represents, the genuine inward turning of the heart to God through the resurrection of Jesus Christ. The water is the sign of the thing. Not the thing itself. Furthermore, Peter connects the saving specifically to the resurrection of Jesus Christ, not to the water. The saving is by the resurrection. The baptism is the pledge. The resurrection is the power.
This reading is consistent with Paul’s explicit separation of baptism from the gospel in 1 Corinthians 1:17, with the thief on the cross, and with the general New Testament framework in which the internal reality, repentance and faith, is always the ground of salvation and the external sign, baptism, is always the public declaration of that internal reality.
What About Acts 2:38?
The second most commonly cited proof text for baptismal regeneration is Peter’s Pentecost sermon: “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins” (Acts 2:38). The argument runs: Peter commands baptism for the remission of sins, therefore baptism is a condition of the remission of sins. Two observations.
First — the Greek preposition eis translated for in this verse is the same preposition used in Matthew 12:41 when Jesus says the people of Nineveh repented at, eis, the preaching of Jonah. The preposition can indicate cause (repent in order to receive remission) or it can indicate basis (repent on the basis of the remission already received). The preposition alone does not settle the interpretive question.
Second — the rest of Peter’s Pentecost preaching makes clear that the remission of sins is grounded in the death and resurrection of Christ, received through faith. Peter calls for repentance as the primary response, “Repent therefore” (Acts 3:19), and in Acts 10:43 declares: “To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins”, without any mention of baptism as a condition. Belief, pisteuo, saving faith, is the stated condition for receiving remission of sins. The baptism of Acts 2:38 is the public declaration and sealing of the repentance and faith that precede and ground it.
What About John 3:5?
“Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God” (John 3:5). The baptismal regeneration interpretation reads born of water as water baptism. But this creates a significant contextual problem, Jesus is speaking to Nicodemus before Christian baptism has been instituted, before the cross, before the resurrection, before Pentecost. Nicodemus would have had no framework for understanding water as Christian baptism.
The most contextually coherent interpretation reads water as a reference to natural birth, the amniotic fluid of physical birth, and Spirit as the new birth. Jesus is distinguishing between the first birth (water, physical) and the second birth (Spirit, supernatural), telling Nicodemus that natural descent and physical birth cannot produce the spiritual transformation that entering the kingdom requires.
This reading is consistent with the surrounding context, with Nicodemus’s immediate reference to physical birth in verse 4, and with Jesus’s explanation in verse 6: “That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.” Flesh and Spirit. Natural birth and supernatural birth. Not water baptism and Spirit baptism.
The Right Place for Baptism
Baptism is commanded in the New Testament. It is the first public act of the new believer, the visible, communal declaration that the inward turning to Christ has taken place. It is meaningful, significant, and scripturally required for the obedient believer.
But it does not save. It cannot wash away sin. It has no power to produce the new birth. The new birth is entirely the sovereign work of the Spirit of God, “The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit” (John 3:8). The Spirit moves sovereignly. The water cannot command Him.
Baptism is the fruit of salvation, not its root. The fruit that publicly declares the root has been planted. The outward sign of the inward reality. The pledge of the good conscience toward God that Peter described.
Let it be that, and it is precious. Let it become more than that, a condition of salvation, a completing mechanism for the finished work of Christ, and it has been displaced from its proper place into the position that belongs to Christ alone.
“Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regenerating, and renewing of the Holy Ghost” (Titus 3:5).
The washing of regenerating. Not the washing of water baptism. The washing of the Holy Spirit, who alone can regenerate, who alone can renew, whose sovereign work produces the new birth that no water can produce and no human minister can administer.
