And Crispus - He is mentioned in 1 Corinthians 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.
