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;

let no man beguile you in any wise: for it will not be, except the falling away come first, and the man of sin be revealed, the son of perdition,

Let no man deceive you by any means, for unless there come a revolt first, and the man of sin be revealed, the son of perdition,

Let not any one deceive you in any manner, because it will not be unless the apostasy have first come, and the man of sin have been revealed, the son of perdition;

let not any one deceive you in any manner, because, if the falling away may not come first, and the man of sin be revealed, the son of the destruction,

Let no one in any way deceive you, for that day cannot come without the coming of the apostasy first, and the appearing of the man of sin, the son of perdition, who sets himself against,

Give no belief to false words: because there will first be a falling away from the faith, and the revelation of the man of sin, the son of destruction,

Let no one deceive you in any way. For it will not be, unless the departure comes first, and the man of lawlessness is revealed, the son of destruction,

Let no one deceive you in any way. For this cannot be, unless the apostasy will have arrived first, and the man of sin will have been revealed, the son of perdition,

Do not let anyone deceive you, whatever he may do. For it will not come until after the Great Apostasy, and the appearing of that Incarnation of Wickedness, that Lost Soul,

Let no man deceive you. That they may not groundlessly promise themselves the arrival in so short a time of the joyful day of redemption, he presents to them a melancholy prediction as to the future scattering of the Church. This discourse entirely corresponds with that which Christ held in the presence of his disciples, when they had asked him respecting the end of the world. For he exhorts them to prepare themselves for enduring hard conflicts, [1] (Matthew 24:6,) and after he has discoursed of the most grievous and previously unheard of calamities, by which the earth was to be reduced almost to a desert, he adds, that the end is not yet, but that these things are the beginnings of sorrows. In the same way, Paul declares that believers must exercise warfare for a long period, before gaining a triumph. We have here, however, a remarkable passage, and one that is in the highest degree worthy of observation. This was a grievous and dangerous temptation, which might shake even the most confirmed, and make them lose their footing -- to see the Church, which had by means of such labors been raised up gradually and with difficulty to some considerable standing, fall down suddenly, as if torn down by a tempest. Paul, accordingly, fortifies beforehand the minds, not merely of the Thessalonians, but of all the pious, that when the Church should come to be in a scattered condition, they might not be alarmed, as though it were a thing that was new and unlooked for. As, however, interpreters have twisted this passage in various ways, we must first of all endeavor to ascertain Paul's true meaning. He says that the day of Christ will not come, until the world has fallen into apostasy, and the reign of Antichrist has obtained a footing in the Church; for as to the exposition that some have given of this passage, as referring to the downfall of the Roman empire, it is too silly to require a lengthened refutation. I am also surprised, that so many writers, in other respects learned and acute, have fallen into a blunder in a matter that is so easy, were it not that when one has committed a mistake, others follow in troops without consideration. Paul, therefore, employs the term apostasy to mean -- a treacherous departure from God, and that not on the part of one or a few individuals, but such as would spread itself far and wide among a large multitude of persons. For when apostasy is made mention of without anything being added, it cannot be restricted to a few. Now, none can be termed apostates, but such as have previously made a profession of Christ and the gospel. Paul, therefore, predicts a certain general revolt of the visible Church. "The Church must be reduced to an unsightly and dreadful state of ruin, before its full restoration be effected." From this we may readily gather, how useful this prediction of Paul is, for it might have seemed as though that could not be a building of God, that was suddenly overthrown, and lay so long in ruins, had not Paul long before intimated that it would be so. Nay more, many in the present day, when they consider with themselves the long-continued dispersion of the Church, begin to waver, as if this had not been regulated by the purpose of God. The Romanists, also, with the view of justifying the tyranny of their idol, make use of this pretext -- that it was not possible that Christ would forsake his spouse. The weak, however, have something here on which to rest, when they learn that the unseemly state of matters which they behold in the Church was long since foretold; while, on the other hand, the impudence of the Romanists is openly exposed, inasmuch as Paul declares that a revolt will come, when the world has been brought under Christ's authority. Now, we shall see presently, why it is that the Lord has permitted the Church, or at least what appeared to be such, to fall off in so shameful a manner. Has been revealed. It was no better than an old wife's fable that was contrived respecting Nero, that he was carried up from the world, destined to return again to harass the Church [2] by his tyranny; and yet the minds of the ancients were so bewitched, that they imagined that Nero would be Antichrist. [3] Paul, however, does not speak of one individual, but of a kingdom, that was to be taken possession of by Satan, that he might set up a seat of abomination in the midst of God's temple -- which we see accomplished in Popery. The revolt, it is true, has spread more widely, for Mahomet, as he was an apostate, turned away the Turks, his followers, from Christ. All heretics have broken the unity of the Church by their sects, and thus there have been a corresponding number of revolts from Christ. Paul, however, when he has given warning that there would be such a scattering, that the greater part would revolt from Christ, adds something more serious -- that there would be such a confusion, that the vicar of Satan would hold supreme power in the Church, and would preside there in the place of God. Now he describes that reign of abomination under the name of a single person, because it is only one reign, though one succeeds another. My readers now understand, that all the sects by which the Church has been lessened from the beginning, have been so many streams of revolt which began to draw away the water from the right course, but that the sect of Mahomet was like a violent bursting forth of water, that took away about the half of the Church by its violence. It remained, also, that Antichrist should infect the remaining part with his poison. Thus, we see with our own eyes, that this memorable prediction of Paul has been confirmed by the event. In the exposition which I bring forward, there is nothing forced. Believers in that age dreamed that they would be transported to heaven, after having endured troubles during a short period. Paul, however, on the other hand, foretells that, after they have had foreign enemies for some time molesting them, they will have more evils to endure from enemies at home, inasmuch as many of those that have made a profession of attachment to Christ would be hurried away into base treachery, and inasmuch as the temple of God itself would be polluted by sacrilegious tyranny, so that Christ's greatest enemy would exercise dominion there. The term revelation is taken here to denote manifest possession of tyranny, as if Paul had said that the day of Christ would not come until this tyrant had openly manifested himself, and had, as it were, designedly overturned the whole order of the Church.

3 - The strange notion here referred to by Calvin as to Nero, is accounted for by Cornelius à Lapide in his Commentary on the Revelation, from the circumstance that Alcazar having explained the expression which occurs in Revelation 13:3, "I saw one of the heads as it were killed to death," as referring to Nero killed, and soon afterwards raised up, as it were, and reviving in the person of Domitian his successor, some of the ancients, understanding literally what was meant by him figuratively, conceived the idea that Nero would be Antichrist, and would be raised up, and appear again in the end of the world. -- Ed.

Let no man deceive you by any means - That is, respecting the coming of the Lord Jesus. This implies that there were then attempts to deceive, and that it was of great importance for Christians to be on their guard. The result has shown that there is almost no subject on which caution is more proper, and on which men are more liable to delusion. The means then resorted to for deception appear from the previous verse to have been either an appeal to a pretended verbal message from the apostle, or a pretended letter from him. The means now, consist of a claim to uncommon wisdom in the interpretation of obscure prophecies of the Scriptures. The necessity for the caution here given has not ceased.
For that day shall not come, except there come a falling away first - Until an apostasy (ἀποστασία apostasia) shall have occurred - the great apostasy. There is scarcely any passage of the New Testament which has given occasion to greater diversity of opinion than this. Though the reference seems to be plain, and there is scarcely any prophecy of the Bible apparently more obvious and easy in its general interpretation; yet it is proper to mention some of the opinions which have been entertained of it.
Some have referred it to a great apostasy from the Christian church, particularly on account of persecution, which would occur before the destruction of Jerusalem. The "coming of the Lord" they suppose refers to the destruction of the holy city, and according to this, the meaning is, that there would be a great apostasy before that event would take place. Of this opinion was Vitringa, who refers the "apostasy" to a great defection from the faith which took place between the time of Nero and Trajan.
Whitby also refers it to an event which was to take place before the destruction of Jerusalem, and supposes that the apostasy would consist in a return from the Christian to the Jewish faith by multitudes of professed converts. The "man of sin," according to him, means the Jewish nation, so characterized on account of its eminent wickedness.
Hammond explains the apostasy by the defection to the Gnostics, by the arts of Simon Magus, whom he supposes to be the man of sin, and by the "day of the Lord" he also understands the destruction of Jerusalem.
Grotius takes Caius Caesar or Caligula, to be the man of sin, and by the apostasy he understands his abominable wickedness. In the beginning of his government, he says, his plans of iniquity were concealed, and the hopes of all were excited in regard to his reign; but his secret iniquity was subsequently "revealed," and his true character understood.
Wetstein understands by the "man of sin," that it referred to Titus and the Flavian house. He says that he does not understand it of the Roman Pontiff, who "is not one such as the demonstrative pronoun thrice repeated designates, and who neither sits in the temple of God, nor calls himself God, nor Caius, nor Simon Gioriae, nor any Jewish impostor, nor Simon Magus."
Koppe refers it to the King mentioned in Daniel 11:36. According to him, the reference is to a great apostasy of the Jews from the worship of God, and the "man of sin" is the Jewish people.
Others have supposed that the reference is to Muhammed, and that the main characteristics of the prophecy may be found in him.
Of the Papists, a part affirm that the apostasy is the falling away from Rome in the time of the Reformation, but the greater portion suppose that the allusion is to Antichrist, who, they say, will appear in the world before the great day of judgment, to combat religion and the saints. See these opinions stated at length, and examined, in Dr. Newton on the Prophecies, Dissertation xxii.
Some more recent expositors have referred it to Napoleon Bonaparte, and some (as Oldshausen) suppose that it refers to some one who has not yet appeared, in whom all the characteristics here specified will be found united.
Most Protestant commentators have referred it to the great apostasy under the papacy, and, by the "man of sin," they suppose there is allusion to the Roman Pontiff, the Pope. It is evident that we are in better circumstances to understand the passage than those were who immediately succeeded the apostles.
Eighteen hundred years have passed (written circa 1880's) away since the Epistle was written, and the "day of the Lord" has not yet come, and we have an opportunity of inquiring, whether in all that long tract of time any one man can be found, or any series of men have arisen, to whom the description here given is applicable. If so, it is in accordance with all the proper rules of interpreting prophecy, to make such an application. If it is fairly applicable to the papacy, and cannot be applied in its great features to anything else, it is proper to regard it as having such an original reference. Happily, the expressions which are used by the apostle are, in themselves, not difficult of interpretation, and all that the expositor has to do is, to ascertain whether in any one great apostasy all the things here mentioned have occurred. If so, it is fair to apply the prophecy to such an event; if not so, we must wait still for its fulfillment.
The word rendered "falling away" (ἀποστασία apostasia, apostasy), is of so general a character, that it may be applied to any departure from the faith as it was received in the time of the apostles. It occurs in the New Testament only here and in Acts 21:21, where it is rendered "to forsake" - "thou teachest all the Jews which are among us to forsake Moses" - apostasy from Moses - ἀποστασίαν ἀπὸ Μωῦσέως apostasian apo Mōuseōs. The word means a departing from, or a defection; see the verb used in 1-Timothy 4:1, "Some shall depart from the faith" - ἀποστήσονται apostēsontai; compare the notes on that passage; see also Hebrews 3:12; Luke 8:13; Acts 5:37. The reference here is evidently to some general falling away, or to some great religious apostasy that was to occur, and which would be under one head, leader, or dynasty, and which would involve many in the same departure from the faith, and in the same destruction. The use of the article here, "the apostasy" (Greek), Erasmus remarks, "signifies that great and before-predicted apostasy." It is evidently emphatic, showing that there had been a reference to this before, or that they understood well that there was to be such an apostasy. Paul says 2-Thessalonians 2:5, that when he was with them, he had told them of these things. The writers in the New Testament often speak of such a defection under the name of Antichrist; see Revelation 13:14; 1-John 2:18, 1-John 2:22; 1-John 4:3; 2-John 1:7.
And that man of sin - This is a Hebraism, meaning a man of eminent wickedness; one distinguished for depravity; compare John 17:12; Proverbs 6:12, in Hebrews. The use of the article here - ὁ ἄνθρωπος ho anthrōpos - "the man of sin," is also emphatic, as in the reference to "the falling away," and shows that there is allusion to one of whom they had before heard, and whose character was well known; who would be the wicked one by way of eminence; see also 2-Thessalonians 2:8, "that wicked" - ὁ ἄνομος ho anomos. There are two general questions in regard to the proper interpretation of this appellative; the one is, whether it refers to an individual, or to a series of individuals of the same general character, aiming at the accomplishment of the same plans; and the other is, whether there has been any individual, or any series of individuals, since the time of the apostle, who, by eminence, deserved to be called "the man of sin." That the phrase, "the man of sin," may refer to a succession of men of the same general character, and that it does so refer here, is evident from the following considerations:
(1) The word "king" is used in Daniel 7:25; Daniel 11:36, to which places Paul seems to allude, to denote a succession of kings.
(2) the same is true of the beast mentioned in Daniel. 7; Daniel. 8; and Revelation. 13, representing a kingdom or empire through its successive changes and revolutions.
(3) the same is true of the "woman arrayed in purple and scarlet" Revelation 17:4, which cannot refer to a single woman, but is the emblem of a continued corrupt administration.
(4) it is clear that a succession is intended here, because the work assigned to "the man of sin," cannot be supposed to be that which could be accomplished by a single individual. The statement of the apostle is, that there were then tendencies to such an apostasy, and that the "man of sin "would be revealed at no distant period, and yet that he would continue his work of "lying wonders" until the coming of the Saviour. In regard to this "man of sin," it may be further observed:
(1) that his appearing was to be preceded by "the great apostasy;" and,
(2) that he was to continue and perpetuate it. His rise was to be owing to a great departure from the faith, and then he was to be the principal agent in continuing it by "signs and lying wonders." He was not himself to originate the defection, but was to be the creation, or result of it. He was to rise upon it, or grow out of it, and, by artful arrangements adapted to that purpose, was to perpetuate it. The question then is, to whom this phrase, descriptive of a succession of individuals so eminent for wickedness that the name "the man of sin" could be applied, was designed by the spirit of inspiration to refer. Dr. Newton has shown that it cannot refer to Caligula, to Simon Magus, to the revolt of the Jews from the Romans, or to the revolt of the Jews from the faith, or to the Flavian family, or to Luther, as some of the papists suppose, or to one man who will appear just before the end of the world, as others of the Romanists suppose; see his Dissertations on the Prophecies, xxii, pp. 393-402; compare Oldshausen, in loc. The argument is too long to be inserted here. But can it be referred to the papacy? Can it denote the Pope of Rome, meaning not a single pope, but the succession? If all the circumstances of the entire passage can be shown to be fairly applicable to him, or if it can he shown that all that is fairly implied in the language used here has received a fulfillment in him, then it is proper to regard it as having been designed to be so applied, and then this may be numbered among the prophecies that are in part fulfilled.
The question now is on the applicability of the phrase "the man of sin" to the Pope. That his rise was preceded by a great apostasy, or departure from the purity of the simple gospel, as revealed in the New Testament, cannot reasonably be doubted by any one acquainted with the history of the church. That he is the creation or result of that apostasy, is equally clear. That he is the grand agent in continuing it, is equally manifest. Is the phrase itself one that is properly applicable to him Is it proper to speak of the Pope of Rome, as he has actually appeared, as "the man of sin?" In reply to this, it might be sufficient to refer to the general character of the papacy, and to its influence in upholding and perpetuating various forms of iniquity in the world. It would be easy to show that there has been no dynasty or system that has contributed so much to uphold and perpetuate sins of various kinds on the earth, as the papacy. No other one has been so extensively and so long the patron of superstition; and there are vices of the grossest character which have all along been fostered by its system of celibacy, indulgences, monasteries, and absolutions. But it would be a better illustration of the meaning of the phrase "man of sin," as applicable to the Pope of Rome, to look at the general character of the popes themselves. Though there may have been some exceptions, yet there never has been a succession of men of so decidedly wicked character, as have occupied the papal throne since the great apostasy commenced.
A very few references to the characters of the popes will furnish an illustration of this point. Pope Vagilius waded to the pontifical throne through the blood of his predecessor. Pope Joan (the Roman Catholic writers tell us) a female in disguise, was elected and confirmed Pope, as John VIII. Platina says, that "she became with child by some of those that were round about her; that she miscarried, and died on her way from the Lateran to the temple." Pope Marcellinus sacrificed to idols. Concerning Pope Honorius, the council of Constantinople decreed, "We have caused Honorius, the late Pope of Old Rome, to be accursed; for that in all things he followed the mind of Sergius the heretic, and confirmed his wicked doctrines." The Council of Basil thus condemned Pope Eugenius: "We condemn and depose Pope Eugenius, a despiser of the holy canons; a disturber of the peace and unity of the church of God; a notorious offender of the whole universal church; a Simonist; a perjurer; a man incorrigible; a schismatic; a man fallen from the faith, and a willful heretic."
Pope John II, was publicly charged at Rome with incest. Pope John XIII usurped the Pontificate, spent his time in hunting, in lasciviousness, and monstrous forms of vice; he fled from the trial to which he was summoned, and was stabbed, being taken in the act of adultery. Pope Sixtus IV licensed brothels at Rome. Pope Alexander VI was, as a Roman Catholic historian says, "one of the greatest and most horrible monsters in nature that could scandalize the holy chair. His beastly morals, his immense ambition, his insatiable avarice, his detestable cruelty, his furious lusts, and monstrous incest with his daughter Lucretia, are, at large, described by Guicciardini Ciaconius, and other authentic papal historians." Of the popes, Platina (a Roman Catholic) says: "The chair of Saint Peter was usurped, rather than possessed, by monsters of wickedness, ambition, and bribery. They left no wickedness unpracticed;" see the New Englander, April, 1844, pp. 285, 286. To no succession of men who have ever lived could the appellative, "the man of sin, be applied with so much propriety as to this succession. Yet they claim to have been the true "successors" of the apostles, and there are Protestants who deem it of essential importance to be able to show that they have derived the true "succession" through such men.
Be revealed - Be made manifest. There were, at the time when the apostle wrote, two remarkable things:
(1) that there was already a tendency to such an apostasy as he spoke of; and,
(2) there was something which as yet prevented the appearance or the rise of the man of sin; 2-Thessalonians 2:7. When the hindrance which then existed should be taken out of the way, he would be manifested; see the notes on 2-Thessalonians 2:7.
"The son of perdition." This is the same appellation which the Saviour bestowed on Judas; see it explained in the notes on John 18:12. It may mean either that he would be the cause of ruin to others, or that he would himself be devoted to destruction. It would seem here rather to be used in the latter sense, though this is not absolutely certain. The phrase, whichever interpretation be adopted, is used to denote one of eminent wickedness.

Except there come a falling away first - We have the original word αποστασια in our word apostasy; and by this term we understand a dereliction of the essential principles of religious truth - either a total abandonment of Christianity itself, or such a corruption of its doctrines as renders the whole system completely inefficient to salvation. But what this apostasy means is a question which has not yet, and perhaps never will be, answered to general satisfaction. At present I shall content myself with making a few literal remarks on this obscure prophecy, and afterwards give the opinions of learned men on its principal parts.
That man of sin - Ὁ ανθρωπος της ἁμαρτιας· The same as the Hebrew expresses by איש און ish aven, and איש בליעל ish beliyaal; the perverse, obstinate, and iniquitous man. It is worthy of remark that, among the rabbins, Samael, or the devil, is called איש בליעל ואיש און ish beliyaal veish aven, the man of Belial, and the man of iniquity; and that these titles are given to Adam after his fall.
The son of perdition - Ὁ υἱος της απωλειας· The son of destruction; the same epithet that is given to Judas Iscariot, John 17:12 (note). The son of perdition, and the man of sin, or, as some excellent MSS. and versions, with several of the fathers, read, ανθρωπος της ανομιας, the lawless man, see 2-Thessalonians 2:8, must mean the same person or thing. It is also remarkable that the wicked Jews are styled by Isaiah, Isaiah 1:4, בנים משחיתים benim mashchithim, "children of perdition;" persons who destroy themselves and destroy others.

Let no man deceive you by any means: (3) for [that day shall not come], except there come a falling away first, and (e) that man of sin be revealed, the son of perdition;
(3) The apostle foretells that before the coming of the Lord, there will be a throne set up completely contrary to Christ's glory, in which that wicked man will sit, and transfer all things that appertain to God to himself: and many will fall away from God to him.
(e) By speaking of one, he singles out the person of the tyrannous and persecuting antichrist.

Let no man deceive you by any means,.... By any of the above means; by pretending to a revelation from the Spirit; or to have had it from the mouth of anyone of the apostles; or to have a letter as from them, declaring the day of Christ to be instant; or by any other means whatever; do not be imposed upon by them for the following reasons, for there were things to be done before the coming of Christ, which were not then done, and which required time: for that day shall not come,
except there come a falling away first; either in a political sense, of the nations from the Roman empire, which was divided into the eastern and western empire; for which, way was made by translating the seat of empire from Rome to Byzantium, or Constantinople; the former of these empires was seized by Mahomet, and still possessed by the Turks; and the latter was overrun by the Goths, Huns, and Vandals, and torn to pieces; Italy particularly was ravaged by them, and Rome itself was sacked and taken: or rather in a religious sense, of the falling of men from the faith of the Gospel, from the purity of Gospel doctrines, discipline, worship, and ordinances; and this not of some Jews who professed faith in Christ, and departed from it, or of some Christians who went off to the Gnostics; but is to be understood of a more general defection in the times of the Papacy; when not only the eastern churches were perverted and corrupted by Mahomet, and drawn off to his religion, but the western churches were most sadly depraved by the man of sin, by bringing in errors of all sorts in doctrine, making innovations in every ordinance, and appointing new ones, and introducing both Judaism and Paganism into the churches; which general defection continued until the times of the reformation, and is what the apostle has respect to in 1-Timothy 4:1 where he manifestly points out some of the Popish tenets, as forbidding marriage to priests, and ordering abstinence from meats on certain days, and at certain times of the year: this was one thing that was to precede the coming of Christ, another follows, which should take place at the same time;
and that man of sin be revealed; who was now hid, though secretly working; by whom is meant not only any particular person or individual; not the devil, for though he is the wicked one, a damned spirit, an opposer, an adversary of God and Christ, and his people, and who has affected deity, and sought to be worshipped, and even by Christ himself; yet the man of sin is here distinguished from Satan, 2-Timothy 2:9 nor is any particular emperor of Rome intended, as Caius Caligula, or Nero, for though these were monsters of iniquity, and set up themselves as gods, yet they sat not in the temple of God; nor is Simon Magus designed, who was a very wicked man, a sorcerer, and who gave out himself to be some great one, and was called the great power of God, before big profession of faith in Christ; and afterwards affirmed that he was God, the Father in Samaria, the Son in Judea, and the Spirit in the rest of the nations of the world; and, because of his signs and lying wonders, had a statue erected by the Roman emperor with this inscription, "to Simon the holy god"; but then this wicked man was now already revealed: nor is this to be understood of a certain Jew, that is to be begotten by the devil on a virgin of the tribe of Daniel, and who is to reign three years and a half, and then to be destroyed by Christ, which is a fable of the Papists; but a succession of men is here meant, as a king is used sometimes for an order and succession of kings, Deuteronomy 17:18 and an high priest for that whole order, from Aaron's time to the dissolution of it, Hebrews 9:7 so here it intends the whole hierarchy of Rome, monks, friars, priests, bishops, archbishops, cardinals, and especially popes, who may well be called "the man of sin", because notoriously sinful; not only sinners, but sin itself, a sink of sin, monsters of iniquity, spiritual wickednesses in high places: it is not easy to reckon up their impieties, their adulteries, incest, sodomy, rapine, murder, avarice, simony, perjury, lying, necromancy, familiarity with the devil, idolatry, witchcraft, and what not? and not only have they been guilty of the most notorious crimes themselves, but have been the patrons and encouragers of others in sin; by dispensing with the laws of God and man, by making sins to be venial, by granting indulgences and pardon for the worst of crimes, by licensing brothel houses, and countenancing all manner of wickedness; and therefore it is no wonder to hear of the following epithet,
the son of perdition; since these are not only the Apollyon, the king of the bottomless pit, the destroyer, the cause of the perdition of thousands of souls, for the souls of men are their wares; but because they are by the righteous judgment of God appointed and consigned to everlasting destruction; the devil, the beast, and the false prophet, will have their portion together in the lake that burns with fire, Revelation 20:10 the same character as here is given of Judas, the betrayer of Christ, John 17:12.

by any means--Greek, "in any manner." Christ, in Matthew 24:4, gives the same warning in connection with the same event. He had indicated three ways (2-Thessalonians 2:2) in which they might be deceived (compare other ways, 2-Thessalonians 2:9, and Matthew 24:5, Matthew 24:24).
a falling away--rather as the Greek, "the falling away," or "apostasy," namely, the one of which "I told you" before (2-Thessalonians 2:5), "when I was yet with you," and of which the Lord gave some intimation (Matthew 24:10-12; John 5:43).
that man of sin be revealed--The Greek order is, "And there have been revealed the man of sin." As Christ was first in mystery, and afterwards revealed (1-Timothy 3:16), so Antichrist (the term used 1-John 2:18; 1-John 4:3) is first in mystery, and afterwards shall be developed and revealed (2-Thessalonians 2:7-9). As righteousness found its embodiment in Christ, "the Lord our righteousness," so "sin" shall have its embodiment in "the man of sin." The hindering power meanwhile restrains its manifestation; when that shall be removed, then this manifestation shall take place. The articles, "the apostasy," and "the man of sin," may also refer to their being well known as foretold in Daniel 7:8, Daniel 7:25, "the little horn speaking great words against the Most High, and thinking to change times and laws"; and Daniel 11:36, the wilful king who "shall exalt and magnify himself above every god, and shall speak marvellous things against the God of gods; neither shall he regard any god."
the son of perdition--a title applied besides to Judas (the traitor, John 17:12), and to none else. Antichrist (the second "beast" coming up out of the earth); therefore he shall at first be "like a lamb, while he speaks as a dragon" (Revelation 13:11); "coming in peaceably and by flatteries," "working deceitfully," but "his heart shall be against the holy covenant" (Daniel 11:21, Daniel 11:23, Daniel 11:28, Daniel 11:30). Seeds of "the falling away" soon appear (1-Timothy 4:1-3), but the full development and concentration of these anti-Christian elements in one person are still to appear. Contrast the King of Zion's coming as JESUS: (1) righteous or just; (2) having salvation; (3) lowly; whereas Antichrist is: (1) "the man of (the embodiment of) sin; (2) the son of perdition; (3) exalting himself above all that is worshipped. He is the son of perdition, as consigning many to it, and finally doomed to it himself (Revelation 17:8, Revelation 17:11). "He whose essence and inheritance is perdition" [ALFORD]. As "the kingdom of heaven" is first brought before us in the abstract, then in the concrete, the King, the Lord Jesus; so here, first we have (2-Thessalonians 2:7) "the mystery of iniquity," then "the iniquitous one" (2-Thessalonians 2:8). Doubtless "the apostasy" of Romanism (the abstract) is one of the greatest instances of the working of the mystery of iniquity, and its blasphemous claims for the Pope (the concrete) are forerunners of the final concentration of blasphemy in the man of sin, who shall not merely, as the Pope, usurp God's honor as vicegerent of God, but oppose God openly at last.

Except there come a falling away first. An apostasy must precede the Coming. That is, there shall be a general falling away from the purity of the faith. No apostasy of magnitude occurred in the history of the church for centuries, which could answer to Paul's description, but the gradual declension, corruption, and departure from the ancient faith, which was fully developed a few hundred years later, has always been spoken of by Protestant church historians as The Apostasy. There is no good reason for doubting that it is to the apostle refers.
And that man of sin be revealed. He shall be revealed then in connection with the apostasy.
The son of perdition. This expression occurs once elsewhere, and is there applied to Judas, an apostate. Here it evidently has a similar application. Some power, once Christian, falls away and becomes opposed to Christ.

Unless the falling away - From the pure faith of the gospel, come first. This began even in the apostolic age. But the man of sin, the son of perdition - Eminently so called, is not come yet. However, in many respects, the Pope has an indisputable claim to those titles. He is, in an emphatical sense, the man of sin, as he increases all manner of sin above measure. And he is, too, properly styled, the son of perdition, as he has caused the death of numberless multitudes, both of his opposers and followers, destroyed innumerable souls, and will himself perish everlastingly. He it is that opposeth himself to the emperor, once his rightful sovereign; and that exalteth himself above all that is called God, or that is worshipped - Commanding angels, and putting kings under his feet, both of whom are called gods in scripture; claiming the highest power, the highest honour; suffering himself, not once only, to be styled God or vice - god. Indeed no less is implied in his ordinary title, "Most Holy Lord," or, "Most Holy Father." So that he sitteth - Enthroned. In the temple of God - Mentioned Revelation 11:1. Declaring himself that he is God - Claiming the prerogatives which belong to God alone.
