Scripture attests that, in the last days, many false prophets will arise to lead the faithful astray. St. John also describes this in Revelation 12 as a confrontation between the “woman clothed in the sun” with the “dragon“, Satan, whom Jesus called “the father of lies.” These false prophets usher in a period of growing lawlessness as the natural and moral law is abandoned for an anti-Gospel, thus preparing the way for the Antichrist. This period is accompanied by what Jesus called “the labor pains.”
II. Exorcism of the Dragon/Illumination**
Satan’s power is broken, but not ended: 
Then war broke out in heaven; Michael and his angels battled against the dragon. The dragon and its angels fought back, but they did not prevail and there was no longer any place for them in heaven. The huge dragon, the ancient serpent, who is called the Devil and Satan, who deceived the whole world, was thrown down to earth, and its angels were thrown down with it… woe to you, earth and sea, for the Devil has come down to you in great fury, for he knows he has but a short time. (Rev 12:7-9, 12)
As I will explain further below, this event may be concomitant with the “illumination” described in Revelation 6, an event which signals that the “day of the Lord” has come: 
Then I watched while he broke open the sixth seal, and there was a great earthquake… Then the sky was divided like a torn scroll curling up, and every mountain and island was moved from its place… They cried out to the mountains and the rocks, “Fall on us and hide us from the face of the one who sits on the throne and from the wrath of the Lamb, because the great day of their wrath has come and who can withstand it?” (Rev 6:12-17)
The “restrainer” of 2 Thess 2 will be removed ushering in the Antichrist to whom the dragon gives his limited power: 
For the mystery of lawlessness is already at work. But the one who restrains is to do so only for the present, until he is removed from the scene. And then the lawless one will be revealed. (2 Thess 2:7-8)
Then I saw a beast come out of the sea with ten horns and seven heads… To it the dragon gave its own power and throne, along with great authority… Fascinated, the whole world followed after the beast. (Rev 13:1-3)
This Antichrist is the false light who will deceive through “every mighty deed and in signs and wonders that lie” those who have refused the graces of Divine Mercy, those who…
…have not accepted the love of truth so that they may be saved. Therefore, God is sending them a deceiving power so that they may believe the lie, that all who have not believed the truth but have approved wrongdoing may be condemned. (2 Thess 2:10-12)
IV. Antichrist Destroyed
Those who follow the Antichrist are given a mark by which they may “buy and sell”. He reigns for a short period, what St. John calls “forty two months,” and then—through a manifestation of Jesus’s power— the Antichrist is destroyed:
…the lawless one will be revealed, whom the Lord [Jesus] will kill with the breath of his mouth and render powerless by the manifestation of his coming. (2 Thess 2:8)
St. Thomas and St. John Chrysostom explain…
that Christ will strike the Antichrist by dazzling him with a brightness that will be like an omen and sign of His Second Coming… The most authoritative view, and the one that appears to be most in harmony with Holy Scripture, is that, after the fall of the Antichrist, the Catholic Church will once again enter upon a period of prosperity and triumph. —The End of the Present World and the Mysteries of the Future Life, Fr. Charles Arminjon (1824-1885), p. 56-57; Sophia Institute Press
All those who followed the Antichrist will likewise become victims of the very “culture of death” they embraced.
The beast was caught and with it the false prophet who had performed in its sight the signs by which he led astray those who had accepted the mark of the beast and those who had worshiped its image. The two were thrown alive into the fiery pool burning with sulfur. The rest were killed by the sword that came out of the mouth of the one riding the horse, and all the birds gorged themselves on their flesh. (cf. Rev 19:20-21)
Since God, having finished His works, rested on the seventh day and blessed it, at the end of the six thousandth year all wickedness must be abolished from the earth, and righteousness reign for a thousand years… —Caecilius Firmianus Lactantius (250-317 A.D.; Ecclesiastical writer), The Divine Institutes, Vol 7
V. Era of Peace
With the death of Antichrist comes the dawning of the “day of the Lord” when the earth is renewed by the Holy Spirit and Christ reigns with his saints for a “thousand years,” a symbolic number indicating an extended period of time.  That is, the prophecies of the Old and New Testament are fulfilled whereby Christ is made known to, and glorified in all the nations before the end of time.
I and every other orthodox Christian feel certain that there will be a resurrection of the flesh followed by a thousand years in a rebuilt, embellished, and enlarged city of Jerusalem, as was announced by the Prophets Ezekiel, Isaias and others… A man among us named John, one of Christ’s Apostles, received and foretold that the followers of Christ would dwell in Jerusalem for a thousand years, and that afterwards the universal and, in short, everlasting resurrection and judgment would take place. —St. Justin Martyr, Dialogue with Trypho, Ch. 81, The Fathers of the Church, Christian Heritage
I am coming to gather all nations and tongues; they shall come and see my glory. I will place a sign among them; from them I will send survivors to the nations… to the distant coastlands which have never heard of my fame, or seen my glory; and they shall proclaim my glory among the nations. (Isaiah 66:18-19)
He will be adored in the Holy Eucharist to the ends of the earth.
From new moon to new moon, and from sabbath to sabbath, all flesh shall come to worship before me, says the LORD. They shall go out and see the corpses of the people who rebelled against me… (Isaiah 66:23-24)
During this period of peace, Satan is chained in the abyss for the “thousand years.”  He will no longer be able to tempt the Church as she grows exponentially in holiness to prepare her for the final coming of Jesus in glory…
…that he might present to himself the church in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. (Eph 5:27)
Therefore, the Son of the most high and mighty God… shall have destroyed unrighteousness, and executed His great judgment, and shall have recalled to life the righteous, who… will be engaged among men a thousand years, and will rule them with most just command… Also the prince of devils, who is the contriver of all evils, shall be bound with chains, and shall be imprisoned during the thousand years of the heavenly rule… —4th century Ecclesiastical writer, Lactantius, “The Divine Institutes”, The ante-Nicene Fathers, Vol 7, p. 211
VI. The End of the World
At the very end, Satan is released from the abyss ushering in the end of time, the Second Coming, the resurrection of the dead, and the final judgment.
We shall indeed be able to interpret the words, “The priest of God and of Christ shall reign with Him a thousand years; and when the thousand years shall be finished, Satan shall be loosed out of his prison;” for thus they signify that the reign of the saints and the bondage of the devil shall cease simultaneously… —St. Augustine, The Anti-Nicene Fathers, City of God, Book XX, Chap. 13, 19
Before the end of the thousand years the devil shall be loosed afresh and shall assemble all the pagan nations to make war against the holy city… “Then the last anger of God shall come upon the nations, and shall utterly destroy them” and the world shall go down in a great conflagration. —4th century Ecclesiastical writer, Lactantius, “The Divine Institutes”, The ante-Nicene Fathers, Vol 7, p. 211
