The Book of Acts says that Peter baptised HOUSEHOLDS. Therfore He must have baptised infants!
Acts does record that Peter baptised Cornelius and his household, those who spoke in tongues.
Acts 10:44 While Peter was still saying these things, the Holy Spirit fell on all who heard the word. 45 And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles. 46 For they were hearing them speaking in tongues and extolling God. Then Peter declared,
47 “Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?”
Notice it records the Spirit fell on those who heard the word, infants can’t understand what we are saying. Now it is possible for very young children to understand the Gospel, a friend of mine recently baptized his 6-year-old son. In addition, those who received the Spirit began talking in tongues and babies can’t speak. Just to clarify, talking in tongues is not insensible babbling, it is talking in a language unknown to the speaker. I have never heard of an infant speaking in tongues. If an early church infant had spoken in tongues I think it would have to have been recorded as a miracle, no less amazing than a healed leper or restored paralytic.
Acts also records Paul preaching to and baptising households, as in chapter 16 with Lydia. However Paul went on to write verses like these.
Romans 10:17 No one can have faith without hearing the message about Christ.
Galatians 3:2 I want to know only one thing. How were you given God’s Spirit? Was it by obeying the Law of Moses or by hearing about Christ and having faith in him?
Just to show that I’m not anti-Catholic, here is a selection from the Didache.
Chapter 7. Concerning Baptism.
And concerning baptism, baptize this way: Having first said all these things, baptize into the name of the Father, and of the Son, and of the Holy Spirit, in living water. But if you have no living water, baptize into other water; and if you cannot do so in cold water, do so in warm. But if you have neither, pour out water three times upon the head into the name of Father and Son and Holy Spirit. But before the baptism let the baptizer fast, and the baptized, and whoever else can; but you shall order the baptized to fast one or two days before.
Notice the command for the baptized to fast a day or two before baptism, clearly not intended for infants. Also note that water poured on the head is a last resort, which makes me think early church baptisms were by immersion.
There are many more passage of Scripture that lead me to believe that conversion and baptism must be made by informed, older children. I’ve posted them many times on CAF so if you would like to hear my rationale feel free to pm me.
