Chaste means not only abstinence from fornication, but also from other passions. And if you are covetous, then you are not chaste, on the contrary, you are even more intemperate, since this passion is not natural. In general, he who is overcome by all passions is not chaste.

In the current century.

This age represents struggle, and the future is retribution.

Waiting for the blessed hope and the manifestation of the glory of our great God and Saviour Jesus Christ.

This is the reward, the Second Coming, truly blessed. He said beautifully: glory. He speaks of two phenomena. The first, as stated above, had grace and forgiveness, which was accomplished with mercy and simplicity. The second is recompense, which is to be revealed with glory, as the Gospel says: "When shall the Son of Man come in His glory" (Matt. 25:31). Where are those who humiliate the Son and do not want to call Him God? Let them hear that He is both God and great. Great, it is said, as God, is not in comparison with anything else, but unconditionally, because He is great in Himself, in nature. If He saved us when we were enemies, what will He not give when He finds us pleasing to Him?

Who gave Himself for us, to deliver us from all iniquity.

And this is a sign of His might, that He gave Himself: and not so as to deliver from one iniquity, but not from another; but from all iniquity. Let us honor our deliverance.

And to purify Himself a special people.

Cleanse with the font of divine baptism and the fulfillment of His divine and purifying commandments. The special (εούο), that is, His, is a metaphorical expression taken from the servants who revolve around the property and possessions of their master, just as a person is called chosen, singled out, who has nothing in common with other people.

Zealous for good deeds.

That is, the people who ardently strive for virtue and show zeal for all good deeds and ardent imitation. Deliverance is His work alone, and to be zealous in works is also ours.

Say this, exhort and rebuke with all authority.

First speak and exhort, that is, teach with more gentle speech; and then rebuke, and not simply, but with all authority, that is, insistently and authoritatively. Since they were rude, he proposes severity against them. There are vices which need no severity, but only exhortation and persuasion, such as that money should be utterly despised. But there are also those that need strictness, such as adultery, theft, predation, and sorcery.

So that no one will neglect you.
