Titus 3:11

εἰδώς : since thou mayest know.

ἐξέστραπται : subversus est. Argument with a man whose basal mental convictions differ from your own, or whose mind has had a twist, is mere waste of breath.

αὐτοκατάκριτος : proprio iudicio condemnatus (Vulg.). He is self-condemned because his separation from the Church is due to his own acknowledged act. He cannot deny that his views are antagonistic to those which he once accepted as true; he is condemned by his former, and, as St. Paul would say, his more enlightened self.
