3:8-11 When the grace of God towards mankind has been declared, the necessity of good works is pressed. Those who believe in God, must make it their care to maintain good works, to seek opportunities for doing them, being influenced by love and gratitude. Trifling, foolish questions must be avoided, and subtle distinctions and vain inquiries; nor should people be eager after novelties, but love sound doctrine which tends most to edifying. Though we may now think some sins light and little, if the Lord awaken the conscience, we shall feel even the smallest sin heavy upon our souls.

10. heretic—Greek "heresy," originally meant a division resulting from individual self-will; the individual doing and teaching what he chose, independent of the teaching and practice of the Church. In course of time it came to mean definitely "heresy" in the modern sense; and in the later Epistles it has almost assumed this meaning. The heretics of Crete, when Titus was there, were in doctrine followers of their own self-willed "questions" reprobated in Tit 3:9, and immoral in practice.

reject—decline, avoid; not formal excommunication, but, "have nothing more to do with him," either in admonition or intercourse.
