CCC 2388
Life in Christ›SECTION TWO THE TEN COMMANDMENTS›CHAPTER TWO YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF›IV. Offenses Against the Dignity of Marriage
Incest designates intimate relations between relatives or in-laws within a degree that prohibits marriage between them. St. Paul stigmatizes this especially grave offense: "It is actually reported that there is immorality among you . . . for a man is living with his father's wife.... In the name of the Lord Jesus ... you are to deliver this man to Satan for the destruction of the flesh...." Incest corrupts family relationships and marks a regression toward animality.
