1 Corinthians 5
A case of sexual immorality—a man living with his father's wife—has arisen, and the Corinthians have boasted rather than mourned, failing to remove the one who did this thing from their midst. Paul issues a directive: deliver this man to Satan for the destruction of the flesh, that his spirit may be saved on the day of the Lord, a severe but redemptive measure. He invokes the Passover: clean out the old leaven, for Christ our Passover lamb has been sacrificed; celebrate the feast with unleavened bread of sincerity and truth, not with the old leaven of malice and evil. Paul clarifies a previous letter he wrote warning against associating with the sexually immoral: he meant those inside the church, not those outside the world, for you are not to judge those outside but only those inside. If someone inside is immoral or a drunkard or swindler, you must not even eat with such a person. God judges those outside; the assembly judges those inside.
