1 Corinthians 5:1-2

1We have heard bad news about what is happening among you. Some of you are having sex in wrong ways. We have heard that one man is even having sex with his own father's wife! Even people who do not know God do not do things as bad as that!

2But, you are still proud of yourselves! Instead, you ought to be very sad and ashamed. You should have sent this man away from your group.
