This is applied according to the aim of both the First Epistle and this Second Epistle. The aim is to keep him from disputes with heretics, so that he does not collect empty and false thoughts and spoil the pattern of sound words.
Moreover, what is fearless Gospel preaching if not preservation of the pattern of sound words and of the apostolic testament?
It is preservation by placing it into the souls of those who hear with faith and believe.
According to this thought, these verses may be considered a continuation of what was said in verse 12, concerning the Apostle’s hope that his deposit will be preserved until that day.
The One who preserves is the Lord. The instruments are the Apostle’s successors, among whom Saint Timothy is perhaps the first.
To him it is said: preserve it and hand it on safely to those who follow. In this way it will be preserved to the end.
“Pattern,” υποτυπωσιν, means outline, norm, prototype. “Of sound words” means of sound teaching.
I have handed down to you, he says, sound teaching concerning salvation. Keep it in mind and heart as a model, and preach the Gospel according to it.
“As painters do, so I have drawn for you the image of virtue and of everything pleasing to God. I have placed in your soul a kind of rule, prototype, and outline” (Chrysostom).
Theophylact says: “Like a painter, I have written and drawn for you an icon and prototype. Looking at it, you too should paint according to it the same outline of my words.
You should paint it in the minds and souls of believers, as on a canvas. Keep this prototype within you. When you need to paint something, take from it and paint, for everything is contained in it.”
Theodoret says: “Imitate painters. They look attentively at the originals and copy images from them exactly.
So you also must have as a kind of original the teaching on faith and love which I handed down to you.”
“Which you heard from me.” “The Apostle instructed his disciple not only by Epistles concerning what he ought to do, but also orally.
He expresses this in many other places, for example when he says, ‘whether by word or by our epistle’ (2 Thess 2:15). But he expresses it much more clearly here.
Therefore let us not think, judging by the written Epistles, that the teaching was handed down by him insufficiently. He handed down much to his disciple without writing, and now he reminds him of it” (Chrysostom).
“In faith and love which are in Christ Jesus.” “In faith and love” may be connected in different ways.
First: keep the outline of my sound words, my teaching, in faith and love. Hold them as in a treasury, in a believing and loving heart.
Second: preserve the outline of my teaching, which embraces both faith and love.
Third: whether you preach about faith or about love, take it from the outline of sound teaching I gave you.
The first meaning may be seen in the words of Chrysostom quoted above: “I placed the prototype and outline in your soul.”
The second meaning appears there also in Chrysostom: “I have drawn for you the image of virtue and of everything pleasing to God.”
It also appears in Theodoret’s words quoted above: “Have as your original the teaching on faith and love handed down by me to you.”
It also appears in Theophylact’s words: “My words contain teaching both on faith and on love, that is, both on dogmas and on the life that is due.”
The third meaning appears in these words of Chrysostom: “If you need to take counsel concerning faith, or love, or chastity, borrow the models from there, that is, from my outline.
You will have no need to seek a model from others, because everything is contained there.”
Theophylact says similarly: “If you need to dogmatize concerning what is due, or to speak, or to act, you should borrow everything from there.”
There is also a fourth understanding, that of Oecumenius. It is that the Apostle uttered his words while being moved by faith and love.
He writes: “His words and instructions were in the faith and love given to him from Christ.”
There is no need to insist on only one understanding, because all of them are admissible, and all necessarily occurred in deed.
The Apostle handed down teaching only as one moved by faith and love, and he taught only the teaching of faith and love.
Saint Timothy received, preserved, and handed on this teaching to others only by faith and love. As it came from his mouth, it concerned nothing other than faith and love.
“Which are in Christ Jesus” grammatically refers to love. In substance, however, it refers not only to love, but also to faith.
So, it seems, one should understand it without being constrained by the form of expression.
This expression indicates both the source and the characteristic mark of faith and love. It means faith and love granted by the Lord and Savior, and held in His Spirit.
