And they spoke the word of the Lord to him and to all who were in his house. And he took them the same hour of the night and washed their wounds; and he was baptized at once, he and all his family. – Acts 16:32-33
Crispus, the ruler of the synagogue, believed in the Lord, together with his entire household. And many of the Corinthians hearing Paul believed and were baptized. – Acts 18:8-9
Some theorize that there were infants included in the household baptisms even thought they’re never explicitly mentioned. For some reason the “and were baptized” is assumed to apply to them but when the entire household “believed in the Lord” that does not. “But the infants are not capable of hearing and believing but are capable of being baptized,” they explain. That just seems like fairly large “Yeah, but” to me. If you just ignore the question of infant baptism for the moment, would you presume that infants were involved here?
