1 Corinthians 5:1-5

It is actually reported that there is sexual immorality among you, and of a kind that is not found even among pagans; for a man is living with his father's wife. And you are arrogant! Should you not rather have mourned, so that he who has done this would have been removed from among you? For though absent in body, I am present in spirit; and as if present I have already pronounced judgment in the name of the Lord Jesus on the man who has done such a thing. When you are assembled, and my spirit is present with the power of our Lord Jesus, you are to hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
