Paul Monachino, Patrick Sayers, and Grace Mahoney 2/11/14 Explaining the Sixth Commandment: You shall not commit adultery: You have heard that it was said, 'You shall not commit adultery. But we say to you that everyone who looks at a woman lustfully has already committed adultery with her in his heart." The sixth commandment upholds chastity as a moral virtue, a gift from God, a grace, a fruit of spiritual effort. Chastity is a moral virtue. The Holy Spirit enables one whom the water of baptism has renewed to imitate the purity of Christ.
