The Man of Sin, the Son of Perdition in the Temple of God!
The Temple of God predicted by St. John in Revelation 11:1-2 to be trodden down for 42 months by the Man of Sin in which the Abomination of Desolation will be set up, putting to an end the Daily Sacrifice of the Mass, is the Seat of the Church in Rome. The notion that the temple that will be desecrated by the Man of Sin will be a rebuilt Jewish temple is a massive Evangelical Protestant deception.
The Son of Perdition sits in the Temple of God
From the Evangelical Catholic Study Bible:
2 Thessalonians 2:1 AND we exhort you, brethren, concerning the coming of our Lord Jesus Christ, and of our gathering together unto Him1 2 that you be not easily shaken in mind, nor be terrified, neither by spirit [an alleged spiritual revelation], nor by word [of some speaker], nor by letter, as [claiming to be] sent from us, as if the Day of the Lord were at hand. 3 Let no man deceive you by any means, for that day will not come unless there first comes the revolt [the apostasy], and the revealing of the Man of Sin, the Son of Perdition [1 Tim. 4:1; Dan.7:25; 8:25; Matt.24:15], 4 who opposes and exalts himself above all that is called God, or that is worshipped,2 so that he sits in the Temple of God 3 [the very Church of Christ!], showing himself as if he were God [Dan. 11:36,37; Ezek.28:2]. 5 Do you not remember that when I was yet with you, I told you these things? 6 And now you know what has been restraining him [from being revealed], that he may be revealed in his time. 7 For the mystery of iniquity already works, only He Who now restrains [the Holy Spirit], does so, until He is taken out of the way [of the Man of Sin]. 8 And then that Wicked One shall be revealed whom the Lord Jesus shall slay with the breath of His mouth, and shall destroy with the brightness of His coming, Yes he, 9 whose coming is according to the working of Satan, with all power, and signs, and lying [deceptive] wonders, 10 and with every kind of wicked seduction toward those who perish, because they received not the love of the truth, that they might be saved [Rev.19:11-20].  Therefore God shall send them a misleading influence, that they may believe a lie. 11 That all may be judged who have not believed the truth, but have delighted in unrighteousness.
2The Man of Sin, the Son of Perdition, the Wicked One: While there have always been those in power who were antichrists (1 Jn.2:18), Holy Scripture is clear that at the end of this age there will arise one who will be the embodiment of all evil and opposition to faith. He will not only oppose Christ and the Church and its pure faith, but all religious faith that speaks of trust in anything outside of man. Faith in any concept of a divine, sovereign, creator God will be the ultimate object of this one’s wrath. Humanism, the worship of man either in its religious form of nature worship (Wicca) or its secular form of raw materialism, is the roadway to this attempt of Satan to make his final attempt to rule and then destroy mankind. Men who choose to fully embrace the sin justified by the free thinking of humanism will not realize that this man, who will seize control in the resulting chaos, is the incarnation of Satan until they are firmly under his power (v.11). (The Anti-Christ: Daniel 7:24-26; 8:23-26; 11:36-45; 1 John 2:18)
3The Temple of God: This can only be the Church founded by our Lord which will be betrayed from within by its Judases just as Our Lord Himself was betrayed. The Church, in its own “passion” and “crucifixion” with its members stripped of all its worldly elements, however, will then also triumph as certainly and gloriously as Christ on Resurrection Sunday. It should be no surprise that there have been many Judases who have betrayed the Church and its faith including Bishops and priests who have tried to use the Church to promote their own interests. It should not surprise us that in the end times the Man of Sin himself will attempt to overthrow the Church and its faith. Many Protestant evangelicals and fundamentalists claim the Temple of God here in the end times is a rebuilt Jewish temple with a reinstituted animal sacrificial system. This, however, could not possibly be because this temple is “the temple of God” and what the Anti-Christ does against this temple is called a desecration by both Daniel and Our Lord (See Daniel 9:27; 12:11; Matt. 24:15). A re-built Jewish temple and its re-instituted sacrificial system would be the desecration. A Jewish temple with its anti-Christian system would certainly not be the Temple of God. Christ has not only replace that temple and its system but utterly condemned it in judgment in AD 70. It is the Church that is desecrated by the presence of the Anti-Christ who cuts off the daily Sacrifice in the very real re-presented once-for-all sacrifice of Christ in the Eucharist.
Further comments: According to Daniel (Daniel 7:24-25) this Man of Sin, this Son of Perdition will arise out of the Roman Empire, revived in the end times by overthrowing three rulers. He will speak against God, “wear out the saints” and try to “change times and laws.” He will rule for “a time and times and a dividing of times,” indicating approximately three and a half years. In Daniel 11:36-45, a text which directly follows a very detailed prophecy fulfilled in the Greek era of persecution of Israel ending under Antiochus Epiphanes in 167 BC, we find an obvious break from that historical period and a projection to what must be a future despot, one who is only prefigured by Antiochus the Greek. This future despot must indeed be the one previously spoken of by Daniel in 7:24-25, the Man of Sin, the one emerging out of the later day Roman Empire. Here is the text:
The Son of Perdition shall speak great things against God
From the Evangelical Catholic Study Bible:
The angel now speaks to Daniel of the Antichrist’s power in the end times (vv. 36-45).
Daniel 11:36 And the king [The Antichrist, the end time Antiochus - v. 35] shall [also] do according to his will, but he shall be lifted up, and shall magnify himself against every god [In contrast to Antiochus, he will be an avowed secular humanist]. And he shall speak great things against the God of gods [The God proclaimed by the Church, and in its tradition and Scriptures], and shall prosper, until the wrath [of God sent through him for mankind’s sins] is accomplished. For the determination is made. 37 And he shall take no account of the God of his fathers, nor follow the desire of women,1 and he shall not regard any gods, for he shall rise up against all things. [He will therefore be worse than Antiochus.] 38 But he shall worship the god Maozim [of forces] in their place, a god whom his fathers knew not. He shall worship with gold, and silver, and precious stones, and things of great price. [He will be a secular materialist who recognizes power as his only god.] 39 And he shall deal with the strongest forces with a strange god [Satan himself!]. For those who acknowledge him he shall increase their glory and shall give them power over many, and shall divide the land for a price. [Rev. 17:12-13]
1The God of his fathers / the desire of women: This may mean no natural desire for women, meaning he will not only be an openly practicing homosexual but will have a radical agenda for its spread, perhaps being as zealous for this as was Hitler in the promotion of his super race. This also may indicate that he will be an advocate of forced sterilization and abortion as the natural desire for women is for bearing children. We are speaking here of one who has no natural moral restraints. Some see a Syrian connection for the coming Antichrist here in an analogy to Antiochus Epiphanes. It does sound like he will come from an either Christian or Moslem background, but will have totally rejected their moral laws. That he favors the “lands of Edom, Moab, and the land of the Ammonites” (v. 41) seems to indicate he will appear to favor the Arab cause.
Daniel 11:40 And at the time of his end [by the will of the sovereign God of Heaven] the king of the south shall fight against him, and the king of the north shall come against him like a tempest, with chariots, and with horsemen [ a 6th century BC accommodation for rapidly moving vehicles], and with a great navy. He shall enter into the countries and shall destroy, and pass through. 41 And he shall enter into the glorious land [of old Israel, or perhaps New Israel in Rome], and many shall fall. And these only shall be saved out of his hand, Edom, and Moab, and the principality of the children of Ammon [these are all Arab territories today east of the Jordan and Dead Sea]. 42 And he shall lay his hand upon the lands. And the land of Egypt shall not escape. 43 And he shall have power over the treasures of gold, of silver, and all the precious things of Egypt. And he shall pass through Libya and Ethiopia. 44 But tidings out of the east and out of the north* shall trouble him and he shall come with a great multitude to destroy and slay many. 45 And he shall fix his tabernacle of his palace between the seas [the Mediterranean and the Dead Sea or the Adriatic and Mediterranean], upon a glorious and holy mountain [of Moriah, or Vatican Hill], but he shall come to an end, and none shall help him. *east / north: May refer to China and to Russia or other forces opposing the Antichrist.
Further comments: The “he” of verse 41b and following through to v. 45 appears to be referring to the coming Man of Sin (the Anti-Christ) who is the anti-type of Antiochus Epiphanes. The “king of the North” in v. 40, from current events, will certainly be Russia that even now is preparing forces against the West and its New World Order takeover. The Man of Sin (the New World Order Anti-Christ) would certainly have aims to take over the Mid-East and Palestine if for no other reason than to establish his Luciferian religion in the Holy Land! The “tidings out of the east and the north” (v.44) that come against The Man of Sin again can only refer to Russia and China who will align themselves against the Seat of Lucifer in the Holy Land. It is indeed striking in this regard that the Apostle John, 575 years later, in his revelation of the pouring out of the Vial Judgment “on the seat of the Beast” (the Anti-Christ), says that “the way of the kings of the east” would be “prepared!” The omission of any reference to the king of the north might well indicate that it will be China that will be the dominate challenge to the Anti-Christ, and that Russia, seen by Daniel, will only play a more minor part in the destruction of the Luciferian New World order that has arisen, also as predicted by Daniel out of the ruins of the Western Roman Empire (Daniel 7)!
Finally, concerning the “Temple of God” that will be desecrated by the Man of Sin by his cutting off its sacrifice and setting up himself as the Abomination of Desolation, it cannot possibly be any rebuilt Jewish temple in Jerusalem with a renewed animal sacrificial system. Such a temple and sacrificial system would itself be an abomination in God’s sight. God ended once and for all that system by the Sacrifice of His Own Son and sent Titus in 70 AD to destroy that temple and system! That so many Evangelical Protestants could come to embrace such a horrendous view shows how their rejection of the true Sacrifice of His Body and Blood that Our Lord so straight forwardly promised in John 6 to those who believed in Him can truly blind even the most sincere followers of Christ. But that so few Catholic Christians have appreciated this “Daily Sacrifice” it will be for three and a half years taken from them!
