Should Babies Be Baptized, or Only Believers Who Profess Faith?
Circumcision, a Greek verb for dipping cloth in dye, and two early church fathers who disagreed about it around AD 200. Let's read the whole case.

A question that splits whole denominations, not just opinions
This isn't a minor disagreement. Presbyterian, Lutheran, Catholic, and Orthodox churches baptize the infant children of believers. Baptist, Pentecostal, and most independent evangelical churches baptize only those old enough to personally repent and believe. Both sides have produced serious theologians, careful Bible readers, and centuries of church history. So let's actually look at why.
The word itself, first
used in everyday Greek for dyeing cloth by dipping it in dye, which is why most traditions see a real washing or immersion as the natural picture behind the word
Worth knowing up front: mode, dunking, pouring, or sprinkling, is actually a separate argument from the one in this article. Churches on both sides of the infant question disagree internally about mode too. The bigger question here is who is a valid candidate for baptism at all: an infant, or only a professing believer.
The covenant case for baptizing infants
Genesis 17:9-14
God gives Abraham circumcision as the sign of His covenant, commanded for every male in the household, including eight-day-old infants who obviously could not yet believe anything.
First written to the people of Israel after the exodus — traditionally Moses, c. 1400–1200 BC · Law (Torah) · Old Covenant
Colossians 2:11-12
Paul calls baptism a circumcision made without hands, and links it directly to being buried with Christ in baptism.
First written to the church in Colossae, facing strange teachings — Paul (writing from prison), c. AD 60–62 · Letter · New Covenant
the same concept Paul draws on when he calls baptism the New Covenant's version of the sign God gave Abraham's whole household, infants included
Paedobaptists reason like this: if circumcision, the Old Covenant sign, was rightly applied to believing households' infants as a mark of belonging to God's covenant people, and Paul explicitly calls baptism its New Covenant counterpart, then withholding baptism from a believer's infant is withholding a sign the Bible's own logic would extend to them. They add supporting texts:
Acts 2:38-39
Peter tells the crowd to repent and be baptized, for the promise is to you and to your children.
First written to Theophilus and Gentile believers seeking certainty — Luke (physician, companion of Paul), c. AD 62–80 · Church history · New Covenant
Acts 16:15 & 16:33
Lydia is baptized along with her household, and later the Philippian jailer is baptized, he and all his household, that very night.
To this camp, household baptisms following the pattern of household circumcision are a strong echo of the Old Testament's family-based sign.
Two different reasons paedobaptists actually give
It's worth knowing paedobaptists don't all agree on why an infant should be baptized:
Covenant sign (Reformed / Presbyterian)
Baptism marks a child's inclusion in the visible covenant community, the way circumcision did, without claiming the infant is already regenerate. Personal faith is still required later, the same way many circumcised Israelites still needed to believe as adults.
Sacramental washing (Catholic / Lutheran)
Baptism itself is the ordinary means God uses to begin His saving work in the child, grounded in texts like John 3:5's "born of water and the Spirit" and Titus 3:5's "washing of regeneration," treating the act itself as carrying real, effectual grace.
The case for baptizing only believers
Acts 8:36-38
The Ethiopian eunuch asks Philip what stops him from being baptized. Philip's answer: if you believe with all your heart, you may. Faith comes first, explicitly, then water.
First written to Theophilus and Gentile believers seeking certainty — Luke (physician, companion of Paul), c. AD 62–80 · Church history · New Covenant
Mark 16:16
Whoever believes and is baptized will be saved. Belief named before baptism, in that order.
First written to Gentile Christians, likely in Rome under pressure — Mark (companion of Peter), c. AD 55–65 · Gospel · New Covenant
Matthew 28:19-20
The Great Commission's own sequence: make disciples, baptizing them, teaching them. Disciple-making, then baptizing, then teaching, all describing people capable of being taught and of following.
First written to Jewish readers — presenting Jesus as the promised Messiah — Matthew (the apostle, a former tax collector), c. AD 60–80 · Gospel · New Covenant
Credobaptists read baptism as a personal, conscious response, a public profession following real repentance and faith, not a family-transmitted covenant sign. On the household texts, they note the passages never actually say infants were present, and in the jailer's case, Luke specifically says the household rejoiced, having believed in God, language that implies people capable of believing, not infants. To this camp, an infant simply cannot yet do the one thing every baptism story in Acts shows happening first: believe.
Believer's baptism (Baptist / free church)
Baptism is an ordinance, a testimony of a faith that has already happened, not a means of producing or covenanting that faith. Since Scripture's own baptism accounts consistently show belief preceding baptism, infants, who cannot yet repent or believe, are not valid candidates. Most of these churches practice a baby dedication instead, followed by baptism once the child can personally profess faith.
What the earliest church actually did
This is one of the rare places where we can look at real, dated historical evidence, not just later opinion.
Irenaeus, bishop of Lyon
c. AD 180, "Against Heresies"
Describes Christ sanctifying every stage of human life, infants included, by passing through each stage Himself
Why this counts: Often read by paedobaptists as reflecting some existing practice of including infants in the church, though the passage doesn't describe a baptism ceremony in detail
Tertullian, North African church father
c. AD 200, "On Baptism"
Explicitly argues believers should delay baptism, including that of young children, until they can ask for it themselves
Why this counts: Strong evidence that infant baptism was already a real, live practice by his time, and was already being pushed back on
So by the year 200, the practice existed somewhere in the church, and it was already disputed. This isn't a modern argument. It's about as old as the earliest Christian writings outside the Bible itself.
What to actually do with this
Read Genesis 17 and Colossians 2 back to back. Then read Acts 8 and Acts 16 back to back. Ask which pattern, covenant family or individual profession, actually governs the text in front of you.
Whichever side of the water you land on, the deeper question is the same for every believer: has your own heart actually believed what your baptism, whenever it happened, was meant to say?
Examine it for yourself
This question genuinely divides careful, Bible-loving denominations, not just casual opinions. If you're facing this decision for yourself or your child, study both cases fully, and talk it through with your own pastor or elders rather than deciding from one article alone.

Does the Bible explicitly command infant baptism?
No single verse directly commands it. Paedobaptists build the case from Colossians 2:11-12, which calls baptism a circumcision without hands, combined with Genesis 17's command to circumcise believing households' infants. Whether that pattern transfers to baptism is exactly what the different camps weigh differently.
Does the Bible explicitly command believer's baptism only?
No single verse states it that plainly either, but credobaptists point to a consistent pattern: every detailed baptism account in Acts, like the Ethiopian eunuch in Acts 8:36-38, shows belief happening before baptism, and Matthew 28:19 orders discipleship before baptizing.
What do the 'household baptism' passages in Acts actually prove?
Paedobaptists read Lydia's household (Acts 16:15) and the jailer's household (Acts 16:33) as likely including infants, following the Old Testament pattern of household circumcision. Credobaptists note the text never states infants were present, and describes the jailer's household as having believed. Both readings are genuinely argued from the same verses.
Did the early church baptize infants?
By around AD 200, the practice existed somewhere in the church and was already disputed. Tertullian explicitly argued for delaying baptism, including for young children, while Irenaeus a few decades earlier described Christ sanctifying every stage of life, infants included. So this debate is genuinely ancient, not a modern invention.
