1 Corinthians 5:1-12

It is actually reported that there is sexual immorality among you, and the kind of sexual immorality that is not even tolerated among the Gentiles  — a man is sleeping with his father’s wife. And you are arrogant! Shouldn’t you be filled with grief and remove from your congregation the one who did this? Even though I am absent in the body, I am present in spirit. As one who is present with you in this way, I have already pronounced judgment on the one who has been doing such a thing. When you are assembled in the name of our Lord Jesus, and I am with you in spirit, with the power of our Lord Jesus, hand that one over to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord. Your boasting is not good. Don’t you know that a little leaven leavens the whole batch of dough? Clean out the old leaven so that you may be a new unleavened batch, as indeed you are. For Christ our Passover lamb has been sacrificed. Therefore, let us observe the feast, not with old leaven or with the leaven of malice and evil, but with the unleavened bread of sincerity and truth. I wrote to you in a letter not to associate with sexually immoral people. I did not mean the immoral people of this world or the greedy and swindlers or idolaters; otherwise you would have to leave the world. But actually, I wrote you not to associate with anyone who claims to be a brother or sister and is sexually immoral or greedy, an idolater or verbally abusive, a drunkard or a swindler. Do not even eat with such a person. For what business is it of mine to judge outsiders? Don’t you judge those who are inside?
