1 Corinthians 5:2-6

You are so proud of yourselves, but you should be mourning in sorrow and shame. And you should remove this man from your fellowship. Even though I am not with you in person, I am with you in the Spirit. And as though I were there, I have already passed judgment on this man in the name of the Lord Jesus. You must call a meeting of the church. I will be present with you in spirit, and so will the power of our Lord Jesus. Then you must throw this man out and hand him over to Satan so that his sinful nature will be destroyed and he himself will be saved on the day the Lord returns. Your boasting about this is terrible. Don’t you realize that this sin is like a little yeast that spreads through the whole batch of dough?
