Titus 3:9-11

Revised Standard Version Catholic Edition

⁹ But avoid stupid controversies, genealogies, dissensions, and quarrels over the law, for they are unprofitable and futile. ¹⁰ As for a man who is factious, after admonishing him once or twice, have nothing more to do with him, ¹¹ knowing that such a person is perverted and sinful; he is self-condemned.
