The verse in its languages

Vulgate (Clementine)
Tu autem loquere quæ decent sanam doctrinam :
Greek New Testament (SBLGNT)
Σὺ δὲ λάλει ἃ πρέπει τῇ ὑγιαινούσῃ διδασκαλίᾳ.

Haydock's commentary

Sound doctrine. It is not sufficient to teach sound doctrine, says St. Jerome, if it be not at the same time taught in a manner worthy of itself; that is, if he who teaches it by his words belies it in his actions. (St. Jerome)

The Fathers on this verse

St Augustine On Christian Doctrine, Human Directions Not to Be Despised, Though God Makes the True Teacher

33. Now if any one says that we need not direct men how or what they should teach, since the Holy Spirit makes them teachers, he may as well say that we need not pray, since our Lord says, “Your Father knoweth what things ye have need of before ye ask Him;” or that the Apostle Paul should not have given directions to Timothy and Titus as to how or what they should teach others. And these three apostolic epistles ought to be constantly before the eyes of every one who has obtained the position of a teacher in the Church. In the First Epistle to Timothy do we not read: “These things command and teach?” What these things are, has been told previously. …

St John Chrysostom The Homilies of St. John Chrysostom on Timothy, Titus, and Philemon, Titus 1:12-14

Chap. ii. ver. 1 . “But speak thou the things that become sound doctrine.” This then is uncleanness. They are themselves unclean. But be not thou silent on that account. Do thy part, although they may not receive thee. Advise and counsel them, though they may not be persuaded. Here he censures them more severely. For they who are mad imagine that nothing stands still, yet this arises not from the objects that are seen, but from the eyes that see. Because they are unsteady and giddy, they think that the earth turns round with them, which yet turns not, but stands firm. The derangement is of their own state, not from any affection of the element. So it is here, when the soul is unclean, it thinks all things unclean. Therefore scrupulous observances are no mark of purity, but it is the part of purity to be bold in all things. …

St Ambrose On the Duties of the Clergy, Chapter X. What is seemly is often found in the sacred writings long before it appears in the books of the philosophers. Pythagoras borrowed the law of his silence from David. David's rule, however, is the best, for our first duty is to have due measure in speaking

30. We are instructed and taught that “what is seemly” is put in our Scriptures in the first place. (In Greek it is called πρέπον .) For we read: “A Hymn beseems Thee, O God, in Sion.” In Greek this is: Σοί πρέπει ὕμνος ὁ θεὸς ἐν Σιών . And the Apostle says: “Speak the things which become sound doctrine.” And elsewhere: “For it beseemed Him through Whom are all things and for Whom are all things, in bringing many sons unto glory, to make the Captain of their salvation perfect through sufferings.”
