2 Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ,
and by our gathering together unto him,
2 Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit,
nor by word, nor by letter as from us, as that the day of Christ is at hand.
2 Th 2:3 Let no man deceive you by any means: for that day shall not come, except
there come a falling away first, and that man of sin be revealed, the son of
perdition;
2 Th 2:4 Who opposeth and exalteth himself above all that is called God, or
that is worshipped; so that he as God sitteth in the temple of God, showing
himself that he is God.
2 Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
2 Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2 Th 2:7 For the mystery of iniquity doth already work: only he who now letteth
will let, until he be taken out of the way.
2 Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume
with the spirit of his mouth, and shall destroy with the brightness of his coming:
2 Th 2:9 Even him, whose coming is after the working of Satan with all power
and signs and lying wonders,
2 Th 2:10 And with all deceivableness of unrighteousness in them that perish;
because they received not the love of the truth, that they might be saved.
2 Th 2:11 And for this cause God shall send them strong delusion, that they
should believe a lie:
2 Th 2:12 That they all might be damned who believed not the truth, but had
pleasure in unrighteousness.
Note that in the above passage, Paul tells the church at Thessalonica that the second coming is not near, that there must be a falling away from the faith, a great apostasy that must happen first. Second, the man of sin, the Antichrist must be revealed, but he was being prevented from rising to power by an entity that the Thessalonians already knew about (v.6), because Paul had already told them about it (v.5).
The key here to knowing who the Antichrist is, is understanding who the restrainer was in Paul's time that prevented the rise of Antichrist, for soon after this restrainer was removed, the Antichrist would be evident. So who did the early church understand this restrainer of the Antichrist to be, and when did they expect the Antichrist to rise to power?

Book V, Chapter 30
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.
2. 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. ...
3. 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. For if there are many names found possessing this number, it will be asked which among them shall the coming man bear. It is not through a want of names containing the number of that name that I say this, but on account of the fear of God, and zeal for the truth: for the name Evanthas (EUAN QAS) contains the required number, but I make no allegation regarding it. Then also Lateinos (LATEINOS) has the number six hundred and sixty-six; and it is a very probable [solution], this being the name of the last kingdom [of the four seen by Daniel]. For the Latins are they who at present bear rule: ...

TREATISE ON CHRIST AND ANTICHRIST.
25. Then he says: "A fourth beast, dreadful and terrible; it had iron teeth and claws of brass." And who are these but the Romans? which (kingdom) is meant by the iron--the kingdom which is now established; for the legs of that (image) were of iron. And after this, what remains, beloved, but the toes of the feet of the image, in which part is iron and part clay, mixed together?
And mystically by the toes of the feet he meant the kings who are to arise from among them; as Daniel also says (in the words), "I considered the beast, and lo there were ten horns behind it, among which shall rise another (horn), an offshoot, and shall pluck up by the roots the three (that were) before it."
And under this was signified none other than Antichrist, who is also himself to raise the kingdom of the Jews. He says that three horns are plucked up by the root by him, viz., the three kings of Egypt, and Libya, and Ethiopia, whom he cuts off in the array of battle. And he, after gaining terrible power over all, being nevertheless a tyrant, shall stir up tribulation and persecution against men, exalting himself against them. For Daniel says: "I considered the horn, and behold that horn made war with the saints, and prevailed against them, till the beast was slain and perished, and its body was given to the burning of fire."

ON THE CLAUSE, AND SHALL COME IN GLORY TO JUDGE THE QUICK AND THE DEAD; OF WHOSE
KINGDOM THERE SHALL BE NO END, DANIEL vii. 9--14.
12. But this aforesaid Antichrist is to come when the times of the Roman empire shall have been fulfilled, and the end of the world is now drawing near. There shall rise up together ten kings of the Romans, reigning in different parts perhaps, but all about the same time; and after these an eleventh, the Antichrist, who by his magical craft shall seize upon the Roman power; and of the kings who reigned before him, three he shall humble, and the remaining seven he shall keep in subjection to himself. At first indeed he will put on a show of mildness (as though he were a learned and discreet person), and of soberness and benevolence: and by the lying [108] signs and wonders of his magical deceit a having beguiled the Jews, as though he were the expected Christ, he shall afterwards be characterized by all kinds of crimes of inhumanity and lawlessness, so as to outdo all unrighteous and ungodly men who have gone before him displaying against all men, but especially against us Christians, a spirit murderous and most cruel, merciless and crafty. And after perpetrating such things for three years and six months only, he shall be destroyed by the glorious second advent from heaven of the only-begotten Son of God, our Lord and Saviour Jesus, the true Christ, who shall slay Antichrist with the breath of His mouth, and shall deliver him over to the fire of hell.

Homilies on Second Thessalonians
HOMILY IV. 2 THESSALONIANS ii. 6--9.
"And now ye know that which restraineth, to the end that he may be revealed in his own season. For the mystery of lawlessness doth already work: only there is one that restraineth now, until he be taken out of the way. And then shall be revealed the lawless one, whom the Lord Jesus shall slay with the breath of His mouth, and bring to nought by the manifestation of His coming: even he whose coming is according to the working of Satan."
ONE may naturally enquire, what is that which withholdeth, and after that would know, why Paul expresses it so obscurely. What then is it that withholdeth, that is, hindereth him from being revealed? Some indeed say, the grace of the Spirit, but others the Roman empire, to whom I most of all accede. Wherefore? Because if he meant to say the Spirit, he would not have spoken obscurely, but plainly, that even now the grace of the Spirit, that is the gifts, withhold him. And otherwise he ought now to have come, if he was about to come when the gifts ceased; for they have long since ceased. But because he said this of the Roman empire, he naturally glanced at it, and speaks covertly and darkly. For he did not wish to bring upon himself superfluous enmities, and useless dangers. ... And he did not say that it will be quickly, although he is always saying it--but what? "that he may be revealed in his own season," he says, "For the mystery of lawlessness doth already work." He speaks here of Nero, as if he were the type of Antichrist. For he too wished to be thought a god. And he has well said, "the mystery"; that is, it worketh not openly, as the other, nor without shame. For if there was found a man before that time, he means, who was not much behind Antichrist in wickedness, what wonder, if there shall now be one? But he did not also wish to point him out plainly: and this not from cowardice, but instructing us not to bring upon ourselves unnecessary enmities, when there is noting to call for it. So indeed he also says here. "Only there is one that restraineth now, until he be taken out of the way," that is, when the Roman empire is taken out of the way, then he shall come. And naturally. For as long as the fear of this empire lasts, no one will willingly exit himself, but when that is dissolved, he will attack the anarchy, and endeavor to seize upon the government both of man and of God. For as the kingdoms before this were destroyed, for example, that of the Medes by the Babylonians, that of the Babylonians by the Persians, that of the Persians by the Macedonians, that of the Macedonians by the Romans: so will this also be by the Antichrist, and he by Christ, and it will no longer withhold. And these things Daniel delivered to us with great clearness.
"And then," he says, "shall be revealed the lawless one." And what after this? The consolation is at hand. "Whom the Lord Jesus shall slay with the breath of His mouth, and bring to nought by the manifestation of His coming, even he whose coming is according to the working of Satan."

For what does he [Paul] mean by "For the mystery of iniquity doth already work: only he who now holdeth, let him hold until he be taken out of the way: and then shall the wicked be revealed?" [2 Thess 2] I frankly confess I do not know what he means. ... However, it is not absurd to believe that these words of the apostle, "Only he who now holdeth, let him hold until he be taken out of the way," refer to the Roman empire, as if it were said, "Only he who now reigneth, let him reign until he be taken out of the way." "And then shall the wicked be revealed:" no one doubts that this means Antichrist.

The testimony is clear, the early church fathers quoted above generally expected the Antichrist to rise to power very soon after the fall of pagan Rome as prophesied in the book of Daniel, chapter 7. At the time that Paul wrote to the church at Thessalonica, the Caesars ruled, and until they were removed they restrained the Antichrist from rising to prominence and exercising his power. This is why Paul could not speak openly about the restrainer in his letter, because he did not want to invite unnecessary persecution by identifying Rome openly and predicting its demise. Rome's rule ended in 476 A.D., so the above fathers were writing, in some cases, hundreds of years before the event, demonstrating that they understood prophecy, at least on that point.
There is only one entity that fulfills the timing spoken of by Paul, and expounded upon by the above quoted church fathers, which rose in prominence after the fall and division of the Roman empire in the 5th century, and subsequently took control of both civil and ecclesiastical governments, exactly as prophesied, and that is the papacy of the Roman Catholic Church.
