Therefore, brethren, stand fast, and hold the traditions which you have been taught, whether by word, or our epistle.
All Commentaries on 2 Thessalonians 2:15 Go To 2 Thessalonians 2
John Chrysostom
AD 407
Paul did not instruct Timothy in his duty through letters alone, but also through the spoken word. He shows this, both in many other passages, as where he says, “whether by word or our epistle,” and especially here. Let us not, therefore, suppose that Paul spoke anything imperfectly that was related to doctrine. For he delivered many things to Timothy without writing. He reminds him of these when he says, “Hold fast the form of sound words, which you have heard from me.” After the manner of artists, I have impressed on you the image of virtue, fixing in your soul a sort of rule, model and outline of all things pleasing to God. Therefore, cling to these things, and whether you are meditating on any matter of faith or love, or of a sound mind, form your ideas from what I have taught you. It will not be necessary to consult others for examples, when all has been deposited within yourself.
