"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."
â Acts 2:38
Quick Answer
Faithful Christians disagree here. Paedobaptists baptize the infants of believers as a sign of covenant inclusion, similar to circumcision, citing household baptisms in Acts. Credobaptists reserve baptism for those who can personally profess faith, citing the New Testament pattern of belief always preceding baptism (Acts 2:38; Acts 16:31-33).
A Question That Divides Good Churches
Few questions in church life produce as much sincere disagreement among genuine, Bible-believing Christians as this one. Presbyterian and Reformed churches typically baptize the infants of believing parents. Baptist and many nondenominational churches reserve baptism exclusively for those old enough to personally profess faith. Both sides love Scripture, take it seriously, and are not arguing carelessly.
It helps to understand this is not a debate between people who believe the Bible and people who do not. It is a debate about how certain biblical themes, especially the relationship between the old covenant and the new, fit together.
Lutheran churches hold a related but distinct view of their own, baptizing infants while emphasizing that God's promise, not the parents' faith alone, is what is being applied through the water, worked through the Word attached to it. This means at least three broad positions exist among Bible-believing Christians, not simply two, each with careful theological reasoning behind it.
The Case for Believer's Baptism
Those who baptize only professing believers point to the consistent New Testament pattern: people heard the gospel, believed, and then were baptized, always in that order (Acts 2:38, 41; 8:12; 16:31-33). Nowhere does the New Testament explicitly describe an infant being baptized, and the qualification for baptism in every recorded case is personal faith and repentance, something an infant cannot yet exercise.
This view also emphasizes that baptism symbolizes a believer's own union with Christ's death and resurrection (Romans 6:3-4), a reality that requires personal faith to be true of someone, not merely family connection to a believing parent.
Advocates also note that the great commission itself lists the order deliberately: go and make disciples, baptizing them, and teaching them (Matthew 28:19-20). Discipleship, involving a response of faith, comes logically prior to baptism in Jesus's own instruction, which credobaptists take as further confirmation that baptism was always meant to follow, not precede, a person's own conscious commitment to Christ.
The Case for Infant Baptism
Those who baptize infants argue from the continuity between the old and new covenants. In the Old Testament, infant boys were circumcised as a sign of belonging to God's covenant community, even before they could believe anything themselves (Genesis 17:9-14). Paul describes baptism as the new covenant counterpart to circumcision (Colossians 2:11-12), which suggests to paedobaptists that infants of believers should receive the sign just as they once received circumcision.
They also point to household baptisms in Acts, where entire households, including the Philippian jailer's, were baptized after he believed (Acts 16:31-34), arguing it is reasonable to think households included children too young to profess faith individually.
Paedobaptists further argue that excluding children from the covenant sign would represent a step backward in redemptive history, since children were included under the old covenant sign of circumcision, and nothing in the New Testament explicitly revokes that inclusion. On this reading, the burden of proof lies with those who would exclude children rather than include them.
Paedobaptists also point to 1 Corinthians 7:14, where Paul describes the children of even one believing parent as holy, set apart in some meaningful sense by their parent's faith. While this verse does not explicitly mention baptism, paedobaptist theologians see it as evidence that children of believers already occupy a distinct covenantal status within the church, one they argue baptism should visibly mark rather than withhold until years later.
Where the Weight of the Text Seems to Fall
Taken together, the explicit New Testament examples of baptism consistently connect it to personal, professed faith, and the language used to describe what baptism pictures, dying and rising with Christ, personal cleansing from sin, a good conscience toward God (1 Peter 3:21), all assume a conscious, believing recipient. This is why many conservative evangelical churches practice believer's baptism as the pattern that best fits the explicit New Testament evidence.
That said, this conclusion should be held with humility toward brothers and sisters who read the covenant argument differently. Infant baptism is not a departure from the gospel, and paedobaptist churches affirm the same salvation by grace through faith as credobaptist ones. It is also worth noting that historical practice does not settle a theological question by itself, even though it is often invoked in this debate. Some early church writings from the second and third centuries mention infant baptism, while others emphasize baptism following instruction and a personal profession of faith. The historical record is mixed enough that neither side can rest its case on church history alone, so the strongest arguments on both sides ultimately return to Scripture itself.
What Matters Most If You Are Unsure
If your own family or church tradition practices infant baptism, and you later come to personal faith, most churches, including many paedobaptist ones, will walk with you thoughtfully about what that means for your own profession. If you were baptized as an infant but have never personally trusted Christ, that baptism did not save you, and a personal, conscious faith in Jesus is what you need regardless of your baptismal history.
Whatever conclusion you land on, hold it with conviction and with grace toward others who love Christ and read this differently. This is a matter faithful Christians can disagree on without dividing over the gospel itself.
