Irenaeus — Commentary on Scripture

2 Thessalonians 1:6

You; and to you who are troubled rest with us, at the revealing of our Lord Jesus Christ from heaven with His mighty angels, and in a flame of fire, to take vengeance upon those who know not God, and upon those that obey not the Gospel of our Lord Jesus Christ: who shall also be punished with everlasting destruction from the presence of the Lord, and from the glory of His power; when He shall come to be glorified in His saints, and to be admired in all them who have believed in Him.".
Paul also refers to this event when he says, "If, however, it is a righteous thing with God to recompense tribulation to them that trouble you, and to you that are troubled rest with us, at the revelation of the Lord Jesus from heaven, with His mighty angels, and in a flame of fire."

Against Heresies Book IV

2 Thessalonians 1:9

So says the apostle, in like manner, in the Epistle to the Thessalonians: "Seeing it is a righteous thing with God to recompense tribulation to them that trouble you; and to you who are troubled rest with us, at the revealing of our Lord Jesus Christ from heaven with His mighty angels, and in a flame of fire, to take vengeance upon those who know not God, and upon those that obey not the Gospel of our Lord Jesus Christ: who shall also be punished with everlasting destruction from the presence of the Lord, and from the glory of His power; when He shall come to be glorified in His saints, and to be admired in all them who have believed in Him."

2 Thessalonians 2:4

And again, speaking of Antichrist, he says, "who opposeth and exalteth himself above all that is called God, or that is worshipped."

2 Thessalonians 2:8

With the presence of his coming; .
And therefore God will send them the working of error, that they may believe a lie; that they all may be judged who did not believe the truth, but gave consent to iniquity"

Against Heresies Book V

2 Thessalonians 2:10

And for this reason the apostle says: "Because they received not the love of God, that they might be saved, therefore God shall also send them the operation of error, that they may believe a lie, that they all may be judged who have not believed the truth, but consented to unrighteousness."

Against Heresies Book V

2 Thessalonians 2:11

"But," say they, "God hardened the heart of Pharaoh and of his servants." Those, then, who allege such difficulties, do not read in the Gospel that passage where the Lord replied to the disciples, when they asked Him, "Why speakest Thou unto them in parables?"-"Because it is given unto you to know the mystery of the kingdom of heaven; but to them I speak in parables, that seeing they may not see, and hearing they may not hear, understanding they may not understand; in order that the prophecy of Isaiah regarding them may be fulfilled, Make the heart of this people gross and make their ears dull, and blind their eyes. But blessed are your eyes, which see the things that ye see; and your ears, which hear what ye do hear. For one and the same God [that blesses others] inflicts blindness upon those who do not believe, but who set Him at naught; just as the sun, which is a creature of His, [acts with regard] to those who, by reason of any weakness of the eyes cannot behold his light; but to those who believe in Him and follow Him, He grants a fuller and greater illumination of mind.

"But," say they, "God hardened the heart of Pharaoh and of his servants." Those, then, who allege such difficulties, do not read in the Gospel that passage where the Lord replied to the disciples, when they asked Him, "Why speakest Thou unto them in parables?"-"Because it is given unto you to know the mystery of the kingdom of heaven; but to them I speak in parables, that seeing they may not see, and hearing they may not hear, understanding they may not understand; in order that the prophecy of Isaiah regarding them may be fulfilled, Make the heart of this people gross and make their ears dull, and blind their eyes. But blessed are your eyes, which see the things that ye see; and your ears, which hear what ye do hear. For one and the same God [that blesses others] inflicts blindness upon those who do not believe, but who set Him at naught; just as the sun, which is a creature of His, [acts with regard] to those who, by reason of any weakness of the eyes cannot behold his light; but to those who believe in Him and follow Him, He grants a fuller and greater illumination of mind. In accordance with this word, therefore, does the apostle say, in the Second [Epistle] to the Corinthians: "In whom the god of this world hath blinded the minds of them that believe not, lest the light of the glorious Gospel of Christ should shine [unto them]." And again, in that to the Romans: "And as they did not think fit to have God in their knowledge, God gave them up to a reprobate mind, to do those things that are not convenient." Speaking of antichrist, too, he says clearly in the Second to the Thessalonians: "And for this cause God shall send them the working of error, that they should believe a lie; that they all might be judged who believed not the truth, but consented to iniquity."

2 Thessalonians 2:14

In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is most abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the apostles until now, and handed down in truth.

Against Heresies Book III

2 Thessalonians 3:6

To which course many nations of those barbarians who believe in Christ do assent, having salvation written in their hearts by the Spirit, without paper or ink, and, carefully preserving the ancient tradition, believing in one God, the Creator of heaven and earth, and all things therein, by means of Christ Jesus, the Son of God; who, because of His surpassing love towards His creation, condescended to be born of the virgin, He Himself uniting man through Himself to God, and having suffered under Pontius Pilate, and rising again, and having been received up in splendour, shall come in glory, the Saviour of those who are saved, and the Judge of those who are judged, and sending into eternal fire those who transform the truth, and despise His Father and His advent.
