For the mystery of iniquity does already work: only he who now restrains will do so, until he be taken out of the way.
All Commentaries on 2 Thessalonians 2:7 Go To 2 Thessalonians 2

until he is taken from our midst
that is, until the wicked and the hypocrites who are in the Church which now is hidden departs from the Church. For they suppose that it is to this same mystery John alludes when in his epistle he says, “Little children, it is the last time: and as you have heard that Antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us.” (1Jn 2:18-19 )
