Believer's Baptism in Early Christian Writings
Early Christian writings usually connect baptism with faith and repentance, not with water alone. Justin Martyr, Tertullian, Clement of Alexandria, Origen, Cyprian, and the Didache all speak of baptism as something for believers and repentant people. Key Bible passages include Acts 2:38, Acts 8:12, Acts 22:16, Mark 16:16, and Romans 6:3-4. The evidence is strong for believer-linked baptism, but later writers disagree on rebaptism and church boundaries.

What did early Christians believe about believer's baptism?
Early Christian writings teach that baptism normally came after belief and repentance, and they often tied it to forgiveness of sins and new life in Christ. Justin Martyr, Tertullian, Clement of Alexandria, Origen, Cyprian, and the Didache all connect baptism with faith, repentance, cleansing, or one baptism into the Lord's death. The Bible passages most often used for this are Acts 2:38, Acts 8:12, Acts 22:16, Mark 16:16, and Romans 6:3-4.
The case is broad for baptism after belief, but it is mixed on later church practice details like rebaptism and how to treat people baptized outside the church. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.

Clement of Alexandria, The Instructor (Paedagogus) Direct teaching
... by human faith and divine grace, our transgressions being taken away by one Paeonian medicine, the baptism of the Word. We are washed from all our sins and are no longer entangled in evil. This is the one grace of illumination, that our characters are not the same as before our washing. And since knowledge rises up with illumination, shedding its beams around the mind, the moment we hear, we who were untaught become disciples. Does this, I ask, happen at the coming of this instruction? You cannot tell the time. For instruction leads to faith, and faith with baptism is trained by the Holy Spirit. That this faith is the one universal salvation of humanity, and that there is the same equality before the righteous and loving God, and the same fellowship between Him and all, the apostle showed most clearly when he spoke in this way: "Before faith came, we were kept under the law, shut up to the faith which should afterwards be revealed, so that the law became our schoolmaster to bring us to Christ, that we might be justified by faith; but after that faith has come, we are no longer under a schoolmaster." Do you not hear that we are no longer under that law which came with fear, but

...ity. Excellent. Well then, I say, does He become perfect at the same time as His baptism by John? Clearly. Then He did not learn anything more from him? Certainly not. But is He perfected by the washing of baptism alone, and sanctified by the descent of the Spirit? So it is. The same also takes place in our case, and Christ became our example. Being baptized, we are illuminated. Being illuminated, we become sons. Being made sons, we are made perfect. Being made perfect, we are made immortal. "I," He says, "have said that you are gods, and all sons of the Highest." This work is called by various names: grace, illumination, perfection, and washing. It is called washing, because by it we cleanse away our sins. It is called grace, because by it the penalties that come from transgressions are remitted. It is called illumination, because by it that holy light of salvation is seen, that is, by it we see God clearly. Now we call that perfect which lacks nothing. For what is still lacking to the one who knows God? For it would truly be monstrous if that which is not complete should be called a gift, or act, of God's grace. Since He is perfect, He therefore gives perfect gifts. As at His

Origen, Commentary on John Supporting witness
... body and brought bodily relief, yet also called those who were benefited by them to an exercise of faith. So also the washing with water, which is symbolic of the soul cleansing herself from every stain of wickedness, is no less in itself to him who yields himself to the divine power of the invocation of the Adorable Trinity, the beginning and source of divine gifts. For there are diversities of gifts. This view receives confirmation from the narrative recorded in the Acts of the Apostles, which shows the Spirit to have descended so plainly on those who receive baptism, after the water had prepared the way for Him in those who properly approached the rite. Simon Magus, astonished at what he saw, desired to receive this gift from Peter. But though it was a good thing he desired, he thought to attain it by the mammon of unrighteousness. We next remark in passing that the baptism of John was inferior to the baptism of Jesus which was given through His disciples. Those in Acts 19:2 who were baptized to John's baptism and had not heard whether there was a Holy Spirit were baptized again by the Apostle. Regeneration did not take place with John, but with Jesus through His disciples i

Cyprian, Epistles Direct teaching
...who are not born in the Church can be sons of God! For the blessed apostle declares and proves that baptism is where the old man dies and the new man is born, saying, "He saved us by the washing of regeneration," Titus 3:5. But if regeneration is in the washing, that is, in baptism, how can heresy, which is not the spouse of Christ, give birth to sons for God through Christ? For it is the Church alone which, joined and united with Christ, spiritually bears sons, as the same apostle again says, "Christ loved the Church, and gave Himself for it, that He might sanctify it, cleansing it with the washing of water," Ephesians 5:25-26. If, then, she is the beloved and spouse who alone is sanctified by Christ, and alone is cleansed by His washing, it is clear that heresy, which is not the spouse of Christ, and cannot be cleansed or sanctified by His washing, cannot bear sons to God.
