Sometimes you are told that people say a certain thing and you wonder if they really do. Yesterday in TableTalk Magazine in comments on 1 Corinthians 16:15-18 it actually does say this (italics mine).
We cannot be sure of who made up Stephanas’ household, but there may be here an indirect reference to infant baptism. The infants would have been baptized along with the rest of the household if, in fact, there were infants in the household (see 1 Cor 1:16). In any case, it is worth noting that some commentators believe that Stephanas and his household played a key role in establishing the church in Corinth and that Stephanas may have been an early leader there given the way Paul speaks about them as those who “devoted themselves to the service of the saints” (16:15).
