(1 Cor 5:5)
It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man is sleeping with his father’s wife. 2And you are proud! Shouldn’t you rather have gone into mourning and have put out of your fellowship the man who has been doing this? 3For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. 4So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, 5hand this man over to Satan for the destruction of the flesh,[SUP]a[/SUP] [SUP]b[/SUP] so that his spirit may be saved on the day of the Lord.
