Albert Barnes on Acts 18:8

And Crispus. He is mentioned, in 1Cor 1:14, as having been one of the few whom Paul baptized with his own hands. The conversion of such a man must have tended greatly to exasperate the other Jews, and to further the progress of the Christian faith among the Corinthians.

With all his house. With all his family, Acts 10:2.

And many of the Corinthians. Many even in this voluptuous and wicked city. Perhaps the power of the gospel was never more signal than in converting sinners in Corinth, and rearing a Christian church in a place so dissolute and abandoned. If it was adapted to such a place as Corinth --if a church, under the power of Christian truth, could be organized there--it is adapted to any city; and there is none so corrupt that the gospel cannot change and purify it.

(f) "Crispus" 1Cor 1:14 (+) "with all his house" "with his hold household"
