1 Corinthians 5:4-7

4You have the authority of the Lord Jesus to do this. When you meet together as a group, my spirit will be with you. The power of our Lord Jesus will also be with you.

5When you meet, put this man under Satan's authority. Satan will then destroy the man's body. Then God may save the man's spirit on the day when the Lord Jesus returns.

6You should not be so proud of yourselves. Think about what yeast does in bread. A very small amount of yeast changes the whole loaf of bread.

7The yeast in the flour is like one person who does wrong things. You must remove this old yeast from among you. Then you will be like a new loaf of bread. You are really like a loaf which has no yeast in it. You are pure, because Christ died as a sacrifice on our behalf. He is like the lamb that the Israelites killed for their Passover meal.
