10 αἱρετικὸν ἄνθρωπον μετὰ μίαν καὶ δευτέραν νουθεσίαν παραιτοῦ, 11 εἰδὼς ὅτι ἐξέστραπται ὁ τοιοῦτος καὶ ἁμαρτάνει ὢν αὐτοκατάκριτος. Titus 3:10–11, NA28
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. Titus 3:10–11
Secular humanism, relativism, pluralism, et cetera are worldly philosophies that have invaded the visible Church. These ways of the world when applied to the Church are some of the things that “stirs up division” within the Body of Christ. Other things that cause this would be majoring in minors such as taking things from the Bible that are not explained in detail enough to be taken literally because they are given to us in an arbitrary fashion. Some take these minor points and make them major points in the gospel stirring up division. Also, some simply want to argue. They hate the truth and are not interested in it being explained to them in detail. All of these are the ones Paul was speaking of in Titus 3:10-11. It is a total waste of time to contend with these people continually. There comes a time when, through God’s wisdom, that we move on and have nothing to do with these divisive people.
