James 2:9-11

New Catholic Bible

⁹ However, if you show partiality, you are committing a sin and stand convicted by the law as lawbreakers. ¹⁰ For whoever observes the whole Law but trips up on a single point is held guilty of breaking all of it.

¹¹ The one who said, “You shall not commit adultery,” also said, “You shall not kill.” Now if you do not commit adultery but you do kill, you have become a lawbreaker.
