The key point of that chapter is Paul’s assertion that the Resurrection cannot come until the man of sin has revealed himself.
That is what the second epistle was all about. Until Satan has been cast out of the presence of the Father, and thrown down to Earth, to indwell Earth’s leader, Yeshua’s return cannot happen.
This is the dividing point in scripture between understanding, and mistaken improvisation of various kinds.
I believe that is incorrect. The first four or five Bibles, before the Douay-Rheims, translated the Greek 'apostasia' as departure. That aligns with the other wording of the chapter, indicating that the lawlessness does not become 'unrestrained' until the Bride is Raptured or departed from the earth.
The following is the World English Bible translation, which is a Bible compiled from the earliest manuscripts and properly aligned to the earliest Bibles, 2 Thessalonian 2:
1. Now, brothers, concerning the coming of our Lord Jesus Christ, and our gathering together to him, we ask you not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of Christ had come.3 Let no one deceive you in any way. For it will not be, unless the departure comes first, and the man of sin is revealed, the son of destruction, he who opposes and exalts himself against all that is called God or that is worshiped; so that he sits as God in the temple of God, setting himself up as God. Don't you remember that, when I was still with you, I told you these things? Now you know what is restraining him, to the end that he may be revealed in his own season. For the mystery of lawlessness already works. Only there is one who restrains now, until he is taken out of the way. 8 Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and destroy by the manifestation of his coming; even he whose coming is according to the working of Satan with all power and signs and lying wonders, and with all deception of wickedness for those who are being lost, because they didn't receive the love of the truth, that they might be saved.
The following Bibles translated 'apostasia' as dep[arture:
4th Century Vulgate used the Latin 'rapio'
Wycliffe Bible 1384 Departure
Wycliffe-Pervey Bible 1388 Departure
Tyndale Bible 1526 Departure
Coverdale Bible 1535 Departure
Cranmer Bible 1539 Departure
Geneva Bible 1560 Departing
Breeches Bible 1576 Departing
Rheims Bible 1582 REVOLT
Beza Bible 1583 Departing
Geneva Bible 1608 Departing
King James 1611 Falling away
Read the first three verses in 2 Thess 2 with the departure in the sentence and the meaning pops out straight, agreeing with the rest of the text that came before and that follows. The Restrainer is the Holy Spirit, working through the spiritual Chruch Jesus established. When the restrainer work of the Holy Spirit is taken out of the way THEN the lawless one is revealed.
Rev 3:10 The spirit reveals to John that the faithful ekklesia will be kept from the not only the 'testing of the earth dwellers', but the 'hour of testing' of the earth dwellers: Rev 3:10 Because you have kept the word of My perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell on the earth.
What comes upon the Earth when the restrainer is taken out of the way is the wrath of God. Paul assures that we are not appointed unto wrath, but to obtain salvation. The Rapture of the Church of Jesus The Christ will be Raptured before the wrath of God is poured out upon the earth in growing degrees of severity. The Body of Christ is not due the wrath of God. The crucifixion dealt with that as Jesus took upon Himself the sins of the whole world before His earth walk and after His earth walk. By faith we connect to that sacrifice He made at Calvary. The wrath of man has tormented The Church, but Revelation teaches it is The Wrath of God which will be poured out upon the earth and the Body of Christ is not appointed for that wrath.
