2 Thessalonians 2:7 - Exposition

For the mystery. "Mystery" here denotes something which was unknown or secret before it was revealed (comp. Ephesians 3:3-5 ). So also one of the names of Babylon, the seat of the antichristian power, is Mystery ( Revelation 17:3 ). Of iniquity; rather, of lawlessness; namely, this apostasy which shall precede the coming of the man of sin. The genitive here is that of apposition—"that mystery which is lawlessness,'' whose essence and sphere of operation is lawlessness. Doth already work; or, is already working. The mystery of iniquity even now works in secret; but the man of sin himself will not appear until the restraining power be removed. Even at the time the apostle wrote the seeds of apostasy were already sown; the leaven of lawlessness was fermenting inside Christianity; the foundations of a false Christianity were being laid. Thus the apostle warned the Ephesians that false teachers would arise from among themselves; to Timothy he writes of those perilous times which were then present; and, in his Epistles, mention is made of false practices and doctrines, such as the worship of angels, abstinence from meats, bodily mortifications, and the honour conferred on celibacy. So also John, in his First Epistle, refers to this working of this antichristian power when he says, "Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists ...Every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world" ( 1 John 2:18 ; 1 John 4:3 ). "Antichrist does not step on the scene suddenly without any preparations; on the contrary, a stream of anti-christian sentiment and conduct pervades the whole history of the world" (Olshausen). Only he that now letteth; or, restraineth, the old meaning of the word "let." Will let. These words are not in the original, and ought to be omitted. Until he be taken out of the way. The whole clause ought to be rendered, "The mystery of lawlessness is already working, only until he who restraineth is removed;" when that takes place, when the restraining influence is removed, the mystery of lawlessness will no longer work secretly, but will be openly manifested.
