What apocalyptic events must precede the Day of the Lord, and how are believers instructed to stand fast in 2 Thessalonians 2?

Saint Paul addresses the Thessalonians concerning the glorious arrival of our Lord Jesus Christ and the final assembly of the faithful unto Him, earnestly pleading that they not be agitated in their minds or thrown into panic by prophetic utterances, oral reports, or forged letters purporting to come from the apostles, which falsely claim that the Day of the Lord is already imminent. Paul commands them not to be misled by any deceptive speculation. That final day cannot arrive unless a revolt occurs first, and the lawless man of sin is openly revealed, that doomed son of perdition. The edition’s note says ancient fathers generally understood the revolt as a falling away from the Roman empire, and also proposes, with “perhaps,” a revolt of nations from the Catholic Church. Its historical examples name Mahomet and Luther, and it supposes a wider revolt in Antichrist’s days. The note understands the man of sin as a particular man, citing repetition of the Greek article, and identifies him as the great Antichrist; these are the edition’s interpretations. This supreme adversary will proudly oppose and exalt himself above every object of human worship and every deity, insolently taking his seat within the sanctuary of God and audaciously proclaiming himself to be God. The edition’s temple note gives alternatives: a Jerusalem temple some think will be rebuilt, or a Christian church perverted to the adversary’s worship, comparing the latter to its account of Mahomet and eastern churches. It does not settle the location. Paul reminds the believers that he explicitly explained these prophetic realities to them while he was still physically present in their city.

The apostle reminds the congregation that they know what restraining force currently holds back this evil figure, preventing his premature emergence so that he may be unveiled only at his appointed hour. The covert mystery of lawlessness is already actively at work in the world, held in check only until the present restrainer is removed from the scene. Once that restraint is taken away, the lawless tyrant will be openly unmasked; the chapter gives no length for his reign; the Lord Jesus will slay him with the breath of His mouth and annihilate him by the dazzling brightness of His coming. The arrival of this wicked one will conform to the deceptive operation of Satan, accompanied by counterfeit miracles, deceptive signs, and lying wonders designed to seduce those who are perishing because they refused to embrace the love of the truth that would have saved them. Because they rejected the truth, The edition’s annotation explains God’s sending as permitting deception by lying wonders and false miracles in punishment for not entertaining love of truth. God allows the operation of error to overtake them so that they put their trust in falsehood, with the result that all who refused to believe the truth and took delight in wickedness will face righteous condemnation.

In stark contrast to those who perish, Paul offers perpetual thanks to God for the beloved Thessalonian brethren, whom God chose as firstfruits for salvation through the sanctifying work of the Holy Spirit and firm belief in the truth. God summoned them to this destiny through the proclamation of the apostolic gospel, enabling them to acquire the eternal glory of our Lord Jesus Christ. Therefore, the apostle commands the brethren to stand firm and hold tenaciously to the sacred traditions they were taught, whether transmitted through oral preaching or through his written letters. The edition’s separate tradition note says unwritten traditions are no less to be received than the epistles. Paul closes his instruction with a prayer that our Lord Jesus Christ Himself, and God our Father who loved us and bestowed everlasting consolation and firm hope through grace, may comfort their hearts and strengthen them in every virtuous deed and truthful word.
