Why Baptize Babies?

It feels intuitive: faith is a personal decision, so shouldn't each person make it themselves? Why baptize someone who can't even talk?

Start with what the apostles actually did. When the Philippian jailer came to faith, his whole household was baptized without delay (Acts 16:33). The same pattern shows up with Lydia and her household (Acts 16:15) and the household of Stephanas (1 Corinthians 1:16). In each case, baptism happened within a covenantal family context, not after waiting for every individual to articulate personal consent. The New Testament passages we have don't describe any such waiting period or minimum-age requirement. That silence is worth noticing.

There's also a deeper logic at work. Paul links baptism directly to circumcision: 'In him also you were circumcised with a spiritual circumcision… when you were buried with him in baptism' (Colossians 2:11–12). And circumcision, the sign of entering God's covenant, was given to boys at eight days old (Genesis 17:12), long before personal choice was possible. Covenant membership under the old covenant wasn't grounded in prior self-directed choice. The new covenant doesn't need to be stingier about including children.

Infant baptism also makes a theological point all on its own: grace is not earned. The Catechism puts it plainly, saying the Church and parents would 'deny a child the priceless grace of becoming a child of God were they not to confer Baptism shortly after birth' (CCC 1250). And Jesus himself said, 'Let the little children come to me; do not stop them, for it is to such as these that the kingdom of God belongs' (Mark 10:14). Children are not to be excluded from God's saving welcome. Baptism is how a person is brought into Christ and the life of the Church. The child's faith is then fostered and expressed personally as they grow. But grace doesn't have to wait for permission.
