Titus 3:8-11

Faithful is the saying, and concerning these things I desire that thou affirm confidently, to the end that they who have believed God may be careful to maintain good works. These things are good and profitable unto men: but shun foolish questionings, and genealogies, and strifes, and fightings about the law; for they are unprofitable and vain. A factious man after a first and second admonition refuse; knowing that such a one is perverted, and sinneth, being self-condemned.
