The "man" of sin and the Saints and the Lord's Second Advent ....
~ Justin Martyr (A.D. 110-165)
"Two advents of Christ have been announced: the one, in which He is set forth as suffering, inglorious, dishonored, and crucified; but the other, in which He shall come from heaven with glory, when the man of apostasy, who speaks strange things against the Most High, shall venture to do unlawful deeds on the earth against us the Christians, ... Now it is evident that no one can terrify or subdue us who have believed in Jesus over all the world. For it is plain that, though beheaded, and crucified, and thrown to wild beasts, and chains, and fire, and all other kinds of torture, we do not give up our confession; but the more such things happen, the more do others and in larger numbers become faithful, and worshippers of God through the name of Jesus." [Dialog with Trypho, CX]
~ Irenaeus: Discipled by Polycarp who was discipled by John. (AD. 120-202)
"Moreover, another danger, by no means trifling, shall overtake those who falsely presume that they know the name of Antichrist. For if these men assume one [number], when this [Antichrist] shall come having another, they will be easily led away by him, as supposing him not to be the expected one, who must be guarded against. These men, therefore, ought to learn [what really is the state of the case], and go back to the true number of the name, that they be not reckoned among false prophets. But, knowing the sure number declared by Scripture, that is, six hundred sixty and six, let them await, in the first place, the division of the kingdom into ten; then, in the next place, when these kings are reigning, and beginning to set their affairs in order, and advance their kingdom, [let them learn] to acknowledge that he who shall come claiming the kingdom for himself, and shall terrify those men of whom we have been speaking, having a name containing the aforesaid number, is truly the abomination of desolation. ... It is therefore more certain, and less hazardous, to await the fulfillment of the prophecy, than to be making surmises, and casting about for any names that may present themselves, inasmuch as many names can be found possessing the number mentioned; and the same question will, after all, remain unsolved. ... But he indicates the number of the name now, that when this "man" comes we may avoid him, being aware who he is: ... But when this Antichrist shall have devastated all things in this world, HE will reign for three years and six months, and sit in the temple at Jerusalem; and then the Lord will come from heaven in the clouds, in the glory of the Father, sending this "man" and those who follow "him" into the lake of fire; but bringing in for the righteous the times of the kingdom, that is, the rest, the hallowed seventh day; and restoring to Abraham the promised inheritance, in which kingdom the Lord declared, that many coming from the east and from the west should sit down with Abraham, Isaac, and Jacob." [Irenaeus: Against Heresies, Book V, XXX]
" an apostate and a robber, is anxious to be adored as God; and that, although a mere slave, he wishes himself to be proclaimed as a king. For he being endued with all the power of the devil, shall come, not as a righteous king, nor a legitimate king in subjection to God, but an impious, unjust, and lawless 'one'; as an apostate, iniquitous, and murderous, as a robber, concentrating in himself satanic apostasy, and seeking aside idols to persuade that he himself is God raising up himself as the only idol, having in himself the multifarious errors of the other idols. This he does, in order that they who do worship the devil by means of many abominations, may serve himself by this one idol, of whom the apostle thus speaks in the second Epistle to the Thessalonians."
"And there is therefore in this beast, when "HE"[ ( Antichrist ) comes, a recapitulation made of all sorts of iniquity and of every deceit, in order that all apostate power, flowing into and being shut up in him, may be sent into the furnace of fire...since he sums up in his own person all the commixture of wickedness which took place previous to the deluge, due to the apostasy of the angels."
"In a still clearer light has John, in the Apocalypse, indicated to the Lord s disciples what shall happen in the last times, and concerning the ten kings who shall then arise...These have one mind, and give their strength and power to the beast. These shall make war with the Lamb, and the Lamb shall overcome them, because He is the Lord of lords, and King of kings...And they (Ten Kings) shall lay Babylon waste, and burn her with fire, and shall give their kingdom to the beast, and put the church to flight. After that they shall be destroyed by the coming of our Lord. [Against Heresies V, XXVI, 1]
"But he indicates the number of the name now, that when this man comes 'we' may avoid him, being aware of who he is:...But when this Antichrist shall have devastated all things in this world, he will reign for three years and six months, and sit in the temple in Jerusalem; and then the Lord will come from heaven in the clouds, in the glory of the Father, sending this man and those who follow him into the lake of fire; but bringing in for the righteous the times of the kingdom, that is, the rest, the hallowed seventh day; and restoring to Abraham the promised inheritance, in which kingdom the Lord declared, that many coming from the east and from the west should sit down with Abraham, Isaac, and Jacob. [Against Heresies V, XXX, 2, 4]
"For all these and other words were unquestionably spoken in reference to the resurrection of the just, which takes place after the coming of the Antichrist, and the destruction of nations under his rule; in (the times of) which (resurrection) the righteous shall reign on the earth...and those whom the Lord shall find in the flesh, awaiting Him from heaven, and who have suffered tribulation, as well as escaped the hands of the Wicked 'one' (Antichrist)." [Against Heresies V, XXXV, 1]
~ Hippolytus: Bishop of Portus, was a disciple of Irenaeus who was discipled by Polycarp who was discipled from John.(AD. 170-236)
"As these things, then, are in the future, and as the ten toes of the image are equivalent to (so many) democracies, and the ten horns of the fourth beast are distributed over ten kingdoms, let us look at the subject a little more closely, and consider these matters as in the clear light of a personal survey. The golden head of the image and the lioness denoted the Babylonians; the shoulders and arms of silver, and the bear, represented the Persians and Medes; the belly and thighs of brass, and the leopard, meant the Greeks, who held the sovereignty from Alexander s time; the legs of iron, and the beast dreadful and terrible, expressed the Romans, who hold the sovereignty at present; the toes of the feet which were part clay and part iron, and the ten horns, were emblems of the kingdoms that are yet to rise; the other little horn that grows up among them meant the Antichrist in their midst; the stone that smites the earth and brings judgment upon the world was Christ." [Treatise on Christ and Antichrist, 27,28]
It is proper that we take the Holy Scriptures themselves in hand, and find out from them what, and of what manner, the coming of Antichrist is; on what occasion and at what time that impious one shall be revealed; and whence and from what tribe (he shall come); and what his name is, which is indicated by the number in Scripture; and how he shall work error among the people, gathering them from the ends of the earth; and (how) he shall stir up tribulation and persecution against the saints; and how he shall glorify himself as God; and what his end shall be; and how the sudden appearing of the Lord shall be revealed from heaven; and what the conflagration of the whole world shall be; and what the glorious and heavenly kingdom of the saints is to be, when they reign together with Christ; and what the punishment of the wicked by fire...With respect to his name, it is not in our power to explain it exactly, as the blessed John understood it and was instructed about it, but only to give a conjectural account of it; for when he appears, the blessed one will show us what we seek to know... Wherefore we ought neither to give it out as if this were certainly his name, nor again ignore the fact that he may not otherwise be designated. But having the mystery of God in our heart, we ought in fear to keep faithfully what has been told us by blessed prophets, in order that when those things come to pass, we may be prepared for them, and not be deceived. For when the times advance, he too, of whom these things are said, will be manifest...Now concerning the tribulation of the persecution which is to fall upon the Church from the adversary, John also speaks thus, "And I saw a great and wondrous sign in heaven; a woman clothed with the sun, ... And to the woman were given two wings of a great eagle, that she might fly into the wilderness, where she is nourished for a time, and times, and half a time, from the face of the serpent ...That refers to the one thousand two hundred and threescore days (the half of the week) during which the tyrant is to reign and persecute the Church.... These things then, being come to pass, beloved, and the one week being divided into two parts, and the abomination of desolation being manifested then, and the two prophets and forerunners of the Lord having finished their course, and the whole world finally approaching the consummation, what remains but the coming of our Lord and Saviour Jesus Christ from heaven, for whom we have looked in hope." [Treatise on Christ and Antichrist, 5, 50, 60, 61, 64]
"on account of his tyranny and violence. For the deceiver seeks to liken himself in all things to the Son of God. Christ is a lion, so Antichrist is also a lion; Christ is a king, so Antichrist is also a king. The Savior was manifested as a lamb; so he too in like manner, will appear as a lamb, though within he is a wolf. The Savior came into the world in the circumcision, and he will come in the same manner. The Lord sent apostles among all the nations, and he in like manner will send false apostles. The Savior gathered together the sheep that were scattered abroad, and he in like manner will bring together a people that is scattered abroad. The Lord gave a seal to those who believed on Him; and he will give one in like manner. The Savior appeared in the form of man, and he too will come in the form of a man. The Savior raised up and showed His holy flesh like a temple, and he will raise a temple of stone in Jerusalem."
"He ( Antichrist )will be harsh, severe, passionate, wrathful, terrible, inconstant, dread, morose, hateful, abominable, savage, vengeful, iniquitous. And, bent on casting the whole race of men into the pit of perdition, he will multiply false signs."
When the times are fulfilled, and the ten horns spring from the beast in the last (times), then Antichrist will appear among them. When he makes war against the saints, and persecutes them, then may we expect the manifestation of the Lord from heaven. [Fragments from Commentaries, II, 7]
"shall be sent through every city and country to destroy the faithful; and the saints shall travel from the west to the east, and shall be driven in persecution from the east to the south, while others shall conceal themselves in the mountains and caves; and the abomination shall war against them everywhere, and shall cut them off by the sea and by land by his decree, and shall endeavor by every means to destroy them out of the world; and they shall not be able any longer to sell their own property, nor to buy from strangers, unless one keeps and carries with him the name of the beast, or bears its mark upon his forehead. For then they shall all be driven out from place to place, and dragged from their own homes and haled into prison, and punished with all manner of punishment, and cast out from the whole world." These shall awake to everlasting life."
~ Lactantius (260-330)
"He ( Antichrist ) shall harass the word with an intolerable rule; shall mingle things divine and human; shall contrive things impious to relate, and detestable; shall meditate new designs in his breast, that he may establish the government for himself; he will change the laws, and appoint his own; he ( Antichrist )will contaminate, plunder, spoil, and put to death."
~ Tertullian (c. 160 - 225)
...that the city of fornication may receive from the ten kings its deserved doom, and that the beast Antichrist, with his false prophet may wage war on the Church of God...Since, then, the Scriptures both indicate the stages of the last times, and concentrate on the harvest of the Christian hope in the very end of the world ...Now the privilege of this favor (the resurrection) awaits those who shall at the coming of the Lord be found in the flesh, and who shall, owing to the oppressions of the time of Antichrist, deserve by an instantaneous death, which is accomplished by a sudden change, to become qualified to join the rising saints... [On the Resurrection of the Flesh, XXV, 7 and XLI]
