2 Thessalonians 2:7

“For the mystery of iniquity doth already work, &c.] Or “the mystery of that wicked one”, as the Syriac; meaning either antichrist himself, and the spirit of antichrist, which were already in the world, (<620218>1 John 2:18 4:2), “mystery” being one of the names of antichrist, (<661705>Revelation 17:5) and anciently this word was engraven on the mitres of the popes of Rome: or the evil doctrines and practices of antichrist may be intended; for as the doctrine of the Gospel is called a mystery, and the mystery of godliness; so the doctrines and practices of antichrist may be called the mystery of iniquity, especially as they were now secretly spread, imbibed, and practised: the foundations of…”

“the mystery of iniquity--the counterwork to "the mystery of godliness" (Ti1 3:16). Anti-Christianity latently working, as distinguished from its final open manifestation. "Mystery" in Scripture means, not what remains always a secret, but that which is for a while hidden, but in due time manifested (compare Eph 3:4-5). Satan will resort to a mode of opposition more conformed to the then imminent "appearing" and "presence" of the Saviour, and will anticipate Him with a last effort to maintain the dominion of the world [DE BURGH], just as at His first advent he rushed into open opposition, by taking possession of the bodies of men. "Iniquity," Greek, "lawlessness"; defiant rejection of God's…”

“For the mystery of iniquity - On the meaning of the word mystery, see the notes on Romans 11:25; compare 1 Corinthians 2:7; Ephesians 1:9; Ephesians 3:3; Colossians 1:26. It means properly what is hidden or concealed; not necessarily that which is unintelligible. The “mystery of iniquity” seems here to refer to some hidden or concealed depravity - some form of sin which was working secretly and silently, and which had not yet developed itself. Any secret sources of iniquity in the church - anything that tended to corrupt its doctrines, and to destroy the simplicity of the faith of the gospel, would correspond with the meaning of the word. Doddridge correctly supposes that this may refer to…”

“He will surely be revealed; for the mystery - The deep, secret power of iniquity, just opposite to the power of godliness, already worketh. It began with the love of honour, and the desire of power; and is completed in the entire subversion of the gospel of Christ. This mystery of iniquity is not wholly confined to the Romish church, but extends itself to others also. It seems to consist of, Human inventions added to the written word. Mere outside performances put in the room of faith and love. Other mediators besides the man Christ Jesus. The two last branches, together with idolatry and bloodshed, are the direct consequences of the former; namely, the adding to the word of God. Already…”

“2:7 The power of the coming man of lawlessness (2:3-6) is already at work secretly, like the antichrists of 1 Jn 2:18. • secretly (Greek mustērion): A descriptor commonly used of rituals in the mystery religions (see 2 Thes 2:6). • at work: This connotes supernatural intervention, whether divine (1 Thes 2:13) or, as here, evil (2 Thes 2:9; Eph 2:2). • The one who is holding it back could refer to one who is in opposition to the man of lawlessness; to one who is possessed; or to Satan, the one who possesses (2 Thes 2:9; see study note on 2:6).”
