Drive out a scoffer, and strife will go out, and quarreling and abuse will cease.
9 But avoid foolish controversies, genealogies, dissensions, and quarrels about the law, for they are unprofitable and worthless.
10 As for a person who stirs up division, after warning him once and then twice, have nothing more to do with him,
11 knowing that such a person is warped and sinful; he is self-condemned.
Side note: The procedure for dealing with the factious man differs from the procedure of Matthew 18.
