3:9 But. The reference to the usefulness of correct doctrine in v. 8 sets up the contrast with the worthless nature of the false teaching. As elsewhere in the letters to Timothy and Titus, the exact content of the false teaching is not clear. The point is that it is foolish, unprofitable, and worthless.
3:10-11 Have nothing more to do with him describes the final stage of church discipline (see also 1 Corinthians 5). A divisive person who refuses to repent and change after being confronted (see Matt. 18:15-20) shows himself to be twisted by sin (warped); thus, he is self-condemned. The NT is clear about seeking the repentance of such people, but it is equally clear that refusal to receive rebuke eventually shows that one is not in Christ and must be excluded from the Christian community.
