1 Corinthians 5:1-2, 7

It’s been widely reported that there is gross sexual immorality among you—the kind of immorality that’s so revolting it’s not even tolerated by the social norms of unbelievers. Are you proud of the fact that one of your men is having sex with his stepmother? Shouldn’t this heartbreaking scandal bring you to your knees in tears? You must remove the offender from among you!

So remove every trace of your “leaven” of compromise with sin so that you might become new and pure again. For indeed, you are clean because Christ, our Passover Lamb, has been sacrificed for us.
