1 Corinthians 5:1

Church Discipline

5:1 It is actually reported that sexual immorality exists among you, the kind of immorality that is not permitted even among the Gentiles, so that someone is cohabiting with his father’s wife.

1 Corinthians 6:13

6:13 “Food is for the stomach and the stomach is for food, but God will do away with both.” The body is not for sexual immorality, but for the Lord, and the Lord for the body.
