Yes, I also baptized the household of Stephanas; beyond that I do not remember if I baptized anyone else.
Here the apostle gives an account of his ministry among them. He thanks God he had baptized but a few among them, Crispus, who had been a ruler of a synagogue at Corinth (Act 18:8), Gaius, and the household of Stephanas, besides whom, he says, he did not remember that he had baptized any. But how was this a proper matter for thankfulness?
Commenting on 1 Corinthians 1:14-16
Verse 16. And I baptised also the household. The family. Whether there were any infants in the family, does not appear. It is certain that the family was among the first converts to Christianity in Achaia, and that it had evinced great zeal in aiding those who were Christians. See .
household of Stephanas--"The first-fruits of Achaia," that is, among the first converted there (Co1 16:15, Co1 16:17). It is likely that such "households" included infants (Act 16:33). The history of the Church favors this view, as infant baptism was the usage from the earliest ages.
