1 Corinthians 5:4-6

New Catholic Bible

⁴ In the name of our Lord Jesus Christ, when you have all assembled together and I am with you in spirit through the power of our Lord Jesus, ⁵ you are to hand over this man to Satan to be destroyed in the flesh, so that on the day of the Lord his spirit may be saved.

⁶ Your boasting is not good. Do you not know that a small amount of yeast leavens the whole batch of dough?
