1 Corinthians 5:1-3

It is actually reported that there is sexual immorality among you, and sexual immorality of such a kind as does not exist even among the Gentiles, namely, that someone has his father’s wife.

You have become arrogant and have not mourned instead, so that the one who had done this deed would be removed from your midst.

For I, on my part, though absent in body but present in spirit, have already judged him who has so committed this, as though I were present.
