This epistle is divided into the greeting, and the epistolary narration, at "we ought to give thanks," etc. Again, first the persons greeting are set down; second, the persons greeted; third, the goods wished for. Now these are the same persons as in the first. But three persons greeting are set down, so that the authority of the epistle might appear more robust. Eccles. 4:12: A threefold cord is broken with difficulty. To the church of the Thessalonians, etc. Church means a congregation: which ought to be in God, otherwise it is evil. Of the good one it is said, Ps. 49:5: Gather together his saints to him, etc. In Christ, that is, in faith in him. Rom. 5:2: through whom we have access by faith into this grace. Then he wishes them good things, and first, peace. For it is the beginning of all spiritual gifts. 1 Cor. 15:10: By the grace of God I am what I am. Again, peace, which is the end of men. Ps. 147:14: who has placed your ends as peace, etc. And this from God, etc. James 1:17: Every excellent gift, and every perfect gift, is from above, descending from the Father of lights, etc. And from the Lord Jesus, etc. 2 Pet. 1:4: through whom he has given us the greatest and precious things. We ought to give thanks, etc.

This is the epistolary narration. And first he instructs them concerning the things to come in the last days; second, he admonishes them familiarly concerning certain matters, in the third chapter, at "for the rest, brothers," etc. Again, first he admonishes, as has been said, as to the rewards of the good, and the punishments of the wicked; second, as to the dangers in the time of Antichrist, chapter 2, at "but we ask you," etc. Again, first he gives thanks concerning the preparation for the future judgment; second he describes the judgment itself, at "if indeed it is just." Again, first he gives thanks for their progress; second he shows the fruit of the progress; third, the sign.

He says therefore, we ought to give thanks, etc. For because in the first epistle he commended them for faith and charity and other goods in which they abounded, therefore he says, we ought always to give thanks for you, because the good that you have, I reckon as my own. 3 John 4: I have no greater grace than this, that I hear my children walk in truth. And this to God, without whom nothing good can be done. And this is fitting, because we give thanks for great goods. 2 Macc. 1:11: Having been delivered by God from great dangers, let us give magnificent thanks. Why? Because spiritual goods grow exceedingly. For they are kept perilously, unless a man makes progress in them.

Now among these gifts of God, the first is faith, through which God dwells in us, and in this we make progress according to the intellect. Eph. 3:17: that Christ may dwell through faith in your hearts. And thus man makes progress through knowledge, devotion, and adherence. The second is charity, through which God is in us according to effect. 1 John 4:16: God is charity, and he who abides in charity abides in God, and God in him. And therefore he says, and it abounds. Prov. 15:5: in abundant justice, there is the greatest strength, etc. 1 Thess. 4:9: But concerning brotherly charity we had no need to write to you, for you yourselves have learned from God to love one another, etc.

And then the progress is set down, when he says: so that I glory in it among others, because I reckon what is yours as mine. For the good of disciples is the glory of prelates. Prov. 10:1: A wise son makes a father glad, etc. Prov. 17:6: The crown of old men is their children's children, etc. 2 Cor. 9:2: for which I glory concerning you.

And then he sets down the sign of progress, namely patience, which is shown most of all in tribulations. James 1:12: Blessed is the man who endures temptation, etc. In tribulations there are two things to be kept, namely patience, lest one depart from the faith. James: patience has a perfect work. And faith in persecutions. 1 Cor. 4:12: We suffer persecution and we endure it. Hence he says, in faith, in all your persecutions and tribulations. These tribulations indeed are named from thistles, by which we are pricked inwardly through afflictions. Gen. 3:18: it shall bring forth to you thorns and thistles. Ps. 24:17: The tribulations of my heart are multiplied.

And these things the saints endure on account of two things: namely, on account of the terror of the wicked. For if God does not spare the good in this world, how will he spare the wicked in the future? 1 Pet. 2: but if first from us, what is the end of those who do not believe the Gospel of God, etc. Jer. 49:12: Behold, they to whom there was no judgment, that they should drink the cup, etc. Second, to increase merit. Hence he says, that worthy, etc. For, as it is said in Matt. 11:12, the kingdom of heaven suffers violence, and the violent bear it away. And Luke, last chapter: was it not necessary for Christ to suffer these things, and so enter into his glory? Rom. 8:17: if indeed we suffer with him, that we may also be glorified together with him. Hence he says, for which you also suffer. For the tribulation which is borne for God makes one worthy of the kingdom of God. Matt. 5:10: Blessed are they who suffer persecution, etc. 1 Pet. 4:15: let none of you suffer as a murderer, or a thief, or a reviler, or a coveter of what belongs to others.
