Irenaeus

In his own words on 2 Thessalonians

• 2 Thessalonians 1:6

  And as, in those times, vengeance came from God upon the Egyptians who were subjecting Israel to unjust punishment, so is it now, the Lord truly declaring, "And shall not God avenge His own elect, which cry day and night unto Him? I tell you, that He will avenge them speedily." 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 1:6

  For some of them, beholding Him in glory, saw His glorious life at the Father's right hand; others beheld Him coming on the clouds as the Son of man; and those who declared regarding Him, "They shall look on Him whom they have pierced," indicated His [second] advent, concerning which He Himself says, "Thinkest thou that when the Son of man cometh, He shall find faith on the earth?" 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."

• 2 Thessalonians 1:9

  ...And as the wrath of God did then descend upon the unrighteous, here also does the apostle likewise say: "For the wrath of God shall be revealed from heaven against all ungodliness and unrighteousness of those men who hold back the truth in unrighteousness." And as, in those times, vengeance came from God upon the Egyptians who were subjecting Israel to unjust punishment, so is it now, the Lord truly declaring, "And shall not God avenge His own elect, which cry day and night unto Him? I tell you, that He will avenge them speedily." 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."

  Against Heresies Book 4

• 2 Thessalonians 2:4

  And the Apostle Paul also, saying, "For though ye have served them which are no gods; ye now know God, or rather, are known of God," has made a separation between those that were not [gods] and Him who is God. And again, speaking of Antichrist, he says, "who opposeth and exalteth himself above all that is called God, or that is worshipped." He points out here those who are called gods, by such as know not God, that is, idols. For the Father of all is called God, and is so; and Antichrist shall be lifted up, not above Him, but above those which are indeed called gods, but are not. And Paul himself says that this is true: "We know that an idol is nothing, and that there is none other God but one. For though there be that are called gods, whether in heaven or in earth; yet to us there is but one God, the Father, of whom are all things, and we through Him; and one Lord Jesus Christ, by whom are all things, and we by Him." For he has made a distinction, and separated those which are indeed called gods, but which are none, from the one God the Father, from whom are all things, and, he has confessed in the most decided manner in his own person, one Lord Jesus Christ.

• 2 Thessalonians 2:8

  Of whom also the Apostle Paul again, speaking in the second [Epistle] to the Thessalonians, and at the same time proclaiming the cause of his advent, thus says: "And then shall the wicked one be revealed, whom the Lord Jesus shall slay with the spirit of His mouth, and destroy by the presence of His coming; whose coming [i.e., the wicked one's] is after the working of Satan, in all power, and signs, and portents of lies, and with all deceivableness of wickedness for those who perish; because they did not receive the love of the truth, that they might be saved. 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

  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

• 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. 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." If, therefore, in the present time also, God, knowing the number of those who will not believe, since He foreknows all things, has given them over to unbelief, and turned away His face from men of this stamp, leaving them in the darkness which they have themselves chosen for themselves, what is there wonderful if He did also at that time give over to their unbelief, Pharaoh, who never would have believed, along with those who were with him?

• 2 Thessalonians 2:14

  The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric. This man, as he had seen the blessed apostles, and had been conversant with them, might be said to have the preaching of the apostles still echoing [in his ears], and their traditions before his eyes. Nor was he alone [in this], for there were many still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension having occurred among the brethren at Corinth, the Church in Rome despatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles, proclaiming the one God, omnipotent, the Maker of heaven and earth, the Creator of man, who brought on the deluge, and called Abraham, who led the people from the land of Egypt, spake with Moses, set forth the law, sent the prophets, and who has prepared fire for the devil and his angels. From this document, whosoever chooses to do so, may learn that He, the Father of our Lord Jesus Christ, was preached by the Churches, and may also understand the apostolical tradition of the Church, since this Epistle is of older date than these men who are now propagating falsehood, and who conjure into existence another god beyond the Creator and the Maker of all existing things. To this Clement there succeeded Evaristus. Alexander followed Evaristus; then, sixth from the apostles, Sixtus was appointed; after him, Telephorus, who was gloriously martyred; then Hyginus; after him, Pius; then after him, Anicetus. Sorer having succeeded Anicetus, Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. 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.

• 2 Thessalonians 2:15

  Since therefore we have such proofs, it is not necessary to seek the truth among others which it is easy to obtain from the Church; since the apostles, like a rich man [depositing his money] in a bank, lodged in her hands most copiously all things pertaining to the truth: so that every man, whosoever will, can draw from her the water of life. For she is the entrance to life; all others are thieves and robbers. On this account are we bound to avoid them, but to make choice of the thing pertaining to the Church with the utmost diligence, and to lay hold of the tradition of the truth. For how stands the case? Suppose there arise a dispute relative to some important question among us, should we not have recourse to the most ancient Churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary, [in that case,] to follow the course of the tradition which they handed down to those to whom they did commit the Churches? 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. Those who, in the absence of written documents, have believed this faith, are barbarians, so far as regards our language; but as regards doctrine, manner, and tenor of life, they are, because of faith, very wise indeed; and they do please God, ordering their conversation in all righteousness, chastity, and wisdom. If any one were to preach to these men the inventions of the heretics, speaking to them in their own language, they would at once stop their ears, and flee as far off as possible, not enduring even to listen to the blasphemous address. Thus, by means of that ancient tradition of the apostles, they do not suffer their mind to conceive anything of the [doctrines suggested by the] portentous language of these teachers, among whom neither Church nor doctrine has ever been established.
