9 Do not get involved in foolish discussions about spiritual pedigrees or in quarrels and fights about obedience to Jewish laws. These things are useless and a waste of time. 10 If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them. 11 For people like that have turned away from the truth, and their own sins condemn them.
Matthew Henry's Commentary on Titus 3:9-11
Commentary on Titus 3:8-11
(Read Titus 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.
