1 Corinthians 5:3-7

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, so that his spirit may be saved on the day of the Lord. 6Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? 7Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed.
