Augustine of Hippo : Thus it is that what is obscure in the words of the apostle has given rise to various conjectures. Yet, of one thing there is no doubt, namely, that Paul meant Christ will not come to judge the living and the dead until after his adversary, Antichrist, has come to seduce the souls of the dead. And, of course, the fact that those souls are to be seduced is already a part of God's hidden judgment.… There seems to be some ambiguity in the expression "pretended signs and wonders." It may be that Satan is to deceive men's senses by means of phantasms, in which they imagine they see wonders which are nonexistent. Or perhaps true miracles will lead into deception those who ought to believe that miracles can be done only by God but who mistakenly ascribe them to the devil's power, particularly at a time when Satan is to be given unheard-of power.… What the devil does is done with his own wicked and malign purpose, but it is permitted by God's just judgment so "that all may be judged who have not believed the truth but have preferred wickedness." Thus it comes about that judgments both precede and follow the deception. Those who are deceived are antecedently judged by these judgments of God, covertly just and justly covert, by which he has never ceased to judge even since the first sin of his rational creature. Those are deceived and subsequently judged in a last and overt judgment by Christ Jesus, who is to be the great judge of all judges as he was the victim of the most unjust of all judgments. — City of God 20.19.4 Cyril of Jerusalem : "And his coming is according to the working of Satan with all power and signs and lying wonders." This means that Satan will use him as his personal instrument. Realizing that his own condemnation will be no longer deferred, he will no longer wage war through his ministers in his usual way, but now openly, in person. "With all signs and lying wonders," for the father of falsehood will display his lying works and cheating fantasies, to make the people think they see a dead man raised, when he is not raised, and the lame walking, and the blind receiving sight, when there have been no such cures. — Catechetical Lecture 15:14-15 John Chrysostom : "And with all deceit of unrighteousness for them that are perishing." Why then, you say, did God permit this to be? and what dispensation is this? And what is the advantage of his coming, if it takes place for the ruin of our race? Fear not, beloved, but hear Him saying, "In them that are perishing," he hath strength, who, even if he had not come, would not have believed. What then is the advantage? That these very men who are perishing will be put to silence. How? Because both if he had come, and if he had not come, they would not have believed in Christ; He comes therefore to convict them. For that they may not have occasion to say, that since Christ said that He was God,-although He nowhere said this openly,-but since those who came after proclaimed it, we have not believed. Because we have heard that there is One God from whom are all things, therefore we have not believed. This their pretext then Antichrist will take away. For when he comes, and comes commanding nothing good, but all things unlawful, and is yet believed from false signs alone, he will stop their mouths. For if thou believest not in Christ, much more oughtest thou not to believe in Antichrist. For the former said that He was sent from the Father, but the latter the contrary. For this reason Christ said, "I am come in My Fathers name, and ye receive Me not: if another shall come in his own name, him ye will receive." But we have seen signs, you say. But many and great signs were also wrought in the case of Christ; much more therefore ought ye to have believed in Him. And yet many things were predicted concerning this one, that he is the lawless one, that he is the son of perdition, that his coming is after the working of Satan. But the contrary concerning the other, that He is the Saviour, that He brings with Him unnumbered blessings. — Homily on 2 Thessalonians 4 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. — Against Marcion Book V
