“For that day will not come, unless the apostasy comes first, and the man of lawlessness is revealed, the son of perdition.” This expression is Hellenistic.
That is, that day will not arrive until the apostasy comes, and so forth. Here two events are clearly distinguished: the apostasy, ή α̉ποστασία, and the revelation, or manifestation, of the man of lawlessness.
Some, including Chrysostom, Theodoret, and Augustine, take the abstract concept α̉ποστασία as a person, α̉ποστάτης, “the apostate.” By it they understand the Antichrist himself, of whom he speaks further on.
Others, including Tertullian, Jerome, and Ambrose, refer this word to apostasy from the Roman monarchy, namely, to rebellion against Roman rule.
Yet nowhere in Holy Scripture is this word used for civil or political defection from someone’s authority. It is much more correct to understand here apostasy from the faith (Acts 21:21; 1 Tim 4:1), or complete unbelief in God.
The Savior also foretold that when He came to earth, He would scarcely find faith in Himself (Lk 18:8).
The decline of faith and love will precede the appearance of a particular person. The Apostle calls him the man of lawlessness, or more correctly in Russian, the man of sin, ο̉ α̉́νθρ. τ. α̉μαρτίας, and the son of perdition.
The man of sin is not merely a sinner. He is a man who above all serves sin, personifying sin in himself, and therefore doomed to certain eternal destruction (Jn 17:12).
His sinful qualities and actions are chiefly signified by the fact that he will be the adversary of Christ, ο άντικείμετος. The Apostle John calls him Antichrist (1 Jn 2:18, 22; 1 Jn 4:3; 2 Jn 7).
This is because he will not only strive to oppose Christ and the spread of Christianity. He will represent in himself the complete opposite of Christ in qualities and actions.
Thus, first of all, he will exalt himself “above every so-called god or object of worship,” έπι πάντα λεγόμενον Θεόν ή σέβασμα.
That is, he will treat with contempt everything that people regard as divine, holy, and worthy of reverence. In this both his audacious pride and his coarsest unbelief will be displayed.
The son of perdition will be the enemy not only of the true God, but also of the gods of the pagans (1 Cor 8:5).
His extraordinary pride will be revealed still more in that “he sits in the temple of God as God, presenting himself as God” (2 Thess 2:4).
This, however, is natural. Whoever recognizes no god, and whoever considers himself higher than every deity, directly or indirectly shows that he recognizes only himself as god.
For greater proof of his imaginary height and superiority over other gods, he himself will sit in the temple of God.
That is, he will either place his statues and images in the temples of God, or he will appropriate divine authority to himself and sit on the throne. For sitting on a throne signifies precisely the authority of rule.
“In the temple of God,” είς τὸν ναόν του Θεού, where ναόν means the inner part of the temple, the sanctuary.
The use of the two articles apparently indicates that the Jerusalem temple is meant here. According to the prophecies, it must be rebuilt before the Coming of Christ.
This God-opposing inclination of the stiff-necked Jewish people has acquired sad fame throughout the whole known history of mankind.
It will be manifested especially vividly in their expectation of their earthly messiah, who will be the Antichrist.
The holy Apostle Paul also regarded Judaism as the sphere where the most terrible satanic hatred against the true God must manifest itself.
See 1 Thess 2:14-16: “the Jews, who killed both the Lord Jesus and His prophets, and drove us out, and do not please God, and oppose all men; they hinder us from speaking to the Gentiles that they may be saved, and thus fill up the measure of their sins.”
Given the apostasy from faith that will precede the appearance of the Antichrist, such exaltation of one person above all deities becomes very understandable.
So also does such a profanation of the holy place, represented here by the Antichrist’s sitting in the temples of God.
Not only in ancient times, in the ages of Nebuchadnezzar, Antiochus Epiphanes, Gaius Caligula, and Nero, were statues of kings set in the place of deities, and divine honors demanded for them.
In modern times also, as the French Revolution of the eighteenth century and the Paris Commune of the nineteenth century showed, blasphemy against holy things can appear in monstrous proportions.
So can the rejection of everything worthy of human reverence and the trampling down of all rights.
The coming of the Antichrist had been foretold by the Apostle even earlier, during his stay in Thessalonica. It constituted one of the dogmas of the Christian faith.
