Ambrosiaster : To them he says that the deception of iniquity of his wonders is advancing, who are about to perish; because they have rejected the charity of truth, through which they could have been saved, as the apostles preached, they are delivered to the devil; for they do not want to be saved, they are abandoned by God. — Commentary on 2 Thessalonians Cyprian : Finally, their mind is smitten by these things, and their spirit is dull, and their sense of right is estranged: it is God's wrath that they do not perceive their sins, lest repentance should follow as it is written, "And God gave them the spirit of torpor," that is, that they may not return and be healed, and be made whole after their sins by just prayers and satisfactions. Paul the apostle in his epistle lays it down, and says, "They received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness." — Epistle LIV Irenaeus : Inasmuch, then, as in this world some persons betake themselves to the light, and by faith unite themselves with God, but others shun the light, and separate themselves from God, the Word of God comes preparing a fit habitation for both. For those indeed who are in the light, that they may derive enjoyment from it, and from the good things contained in it; but for those in darkness, that they may partake in its calamities. And on this account He says, that those upon the right hand are called into the kingdom of heaven, but that those on the left He will send into eternal fire for they have deprived themselves of all good. 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." For when he (Antichrist) is come, and of his own accord concentrates in his own person the apostasy, and accomplishes whatever he shall do according to his own will and choice, sitting also in the temple of God, so that his dupes may adore him as the Christ; wherefore also shall he deservedly "be cast into the lake of fire:" [this will happen according to divine appointment], God by His prescience foreseeing all this, and at the proper time sending such a man, "that they may believe a lie, that they all may be judged who did not believe the truth, but consented to unrighteousness;"... — Against Heresies Book 5 John Chrysostom : "For because they received not the love of the truth, that they might be saved; for this cause God will send them a working of error, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness." "That they might be judged." He does not say, that they might be punished; for even before this they were about to be punished; but "that they might be condemned," that is, at the dreadful Seat of Judgment, in order that they might be without excuse. "Who believed not the truth, but had pleasure in unrighteousness." He calls Christ, "the Love of the Truth." "For because," says he, "they received not the love of the truth," For He was both, and came for the sake of both, both as loving men, and on behalf of things that were true. "But had pleasure," he says, "in unrighteousness." For he came to the destruction of men and to injure them. For what will he not then work? He will change and confound all things, both by his commandments, and by the fear of him. He will be terrible in every way, from his power, from his cruelty, from his unlawful commandments. But fear not. "In those that perish" he will have his strength. For Elijah too will then come to give confidence to the faithful, and this Christ says; "Elijah cometh, and shall restore all things." Therefore it is said, "In the spirit and power of Elijah." For he neither wrought signs nor wonders, as Elijah did. For "John," it is said, "did no miracle, but all things which John spake of this Man were true." How then was it "in the spirit and power of Elijah"? That is, he will take upon him the same ministry. As the one was the forerunner of His first Coming, so will the other be of His second and glorious Coming, and for this he is reserved. Let us not therefore fear. He has calmed the minds of the hearers. He causes them no longer to think present things dreadful but worthy of thankfulness. — Homily on 2 Thessalonians 4 Tertullian : You must "seek" until you "find," and believe when you have found; nor have you anything further to do but to keep what you have believed provided you believe this besides, that nothing else is to be believed, and therefore nothing else is to be sought, after you have found and believed what has been taught by Him who charges you to seek no other thing than that which He has taught. When, indeed, any man doubts about this, proof will be forthcoming, that we have in our possession that which was taught by Christ. — The Prescription Against Heretics Tertullian : But whichsoever of the two it is, I want to know why he comes "in all power, and with lying signs and wonders? " "Because," he says, "they received not the love of the truth, that they might be saved; for which cause God shall send them an instinct of delusion (to believe a lie), that they all might be judged who believed not the truth, but had pleasure in unrighteousness." If therefore he be Antichrist, (as we hold), and comes according to the Creator's purpose, it must be God the Creator who sends him to fasten in their error those who did not believe the truth, that they might be saved; His likewise must be the truth and the salvation, who avenges (the contempt of) them by sending error as their substitute -that is, the Creator, to whom that very wrath is a fitting attribute, which deceives with a lie those who are not captivated with truth. — Against Marcion Book V Victorinus of Pettau : "And the beast which ascendeth from the abyss." After many plagues completed in the world, in the end he says that a beast ascended from the abyss. Bat that he shall ascend from the abyss is proved by many testimonies; for he says in the thirty-first chapter of Ezekiel: "Behold, Assur was a cypress in Mount Lebanon." Assur, deeply rooted, was a lofty and branching cypress-that is, a numerous people-in Mount Lebanon, in the kingdom of kingdoms, that is, of the Romans. Moreover, that he says he was beautiful in offshoots, he says he was strong in armies. The water, he says, shall nourish him, that is, the many thousands of men which were subjected to him; and the abyss increased him, that is, belched him forth. For even Isaiah speaks almost in the same words; moreover, that he was in the kingdom of the Romans, and that he was among the Caesars. The Apostle Paul also bears witness, for he says to the Thessalonians: "Let him who now restraineth restrain, until he be taken out of the way; and then shall appear that Wicked One, even he whose coining is after the working of Satan, with signs and lying wonders." And that they might know that he should come who then was the prince, he added: "He already endeavours after the secret of mischief" -that is, the mischief which he is about to do he strives to do secretly; but he is not raised up by his own power, nor by that of his father, but by command of God, of which thing Paul says in the same passage: "For this cause, because they have not received the love of God, He will send upon them a spirit of error, that they all may be persuaded of a lie, who have not been persuaded of the truth." And Isaiah saith: "While they waited for the light, darkness arose upon them." Therefore the Apocalypse sets forth that these prophets are killed by the same, and on the fourth day rise again, that none might be found equal to God. — Victorinus Commentary on the Apocalypse of the Blessed John
