2Thessalonians1:7-10 is Jesus's return to end the great tribulation, agreed. Returning with the armies of heaven, who are the mighty angels. Surrounded in the glory of his saints.
The rapture/resurrection of them in Christ of 1Thessalonians4:14-17 takes place before the great tribulation begins near the middle of the 7 years. The rapture/resurrection may happen before the 70th week begins, or after it begins, but before the Antichrist goes into the temple, sits, claims to have achieved God-hood.
The two most important words to Christians, past, present, future in all these chapters is "in Christ".
You made a bunch of statements here without doing anything to back them up. Did you think this was going to be convincing to anyone?
If you could set your doctrine aside for a minute and pretend that you weren't already set in your beliefs, and you then read 2 Thess 1:10 where it says "He shall come to be glorified in His saints, and to be admired in all them that believe", can you honestly tell me it wouldn't bring to mind the gathering of believers to meet Christ "in the air"?
2 Thess 1:7 And to you who are troubled rest with us, when
the Lord Jesus shall be revealed from heaven with his mighty angels, 8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: 9 Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;10
When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed)
in that day.
The following passage is describing the same event as the passage above only in reverse order (it talks about what happens to believers first, followed by what will happen to unbelievers instead of the other way around):
1 Thess 4:15 For this we say unto you by the word of the Lord, that we which are alive and remain unto
the coming of the Lord shall not prevent them which are asleep. 16 For
the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and
the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words. 5:1 But of the times and the seasons, brethren, ye have no need that I write unto you. 2 For yourselves know perfectly that
the day of the Lord so cometh as a thief in the night. 3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child;
and they shall not escape. 4 But
ye, brethren, are not in darkness, that that day should overtake you as a thief.
It's quite clear that 2 Thess 1:7-10 and 1 Thess 4:14-5:6 are speaking of the same event. Both speaks of the coming of Christ (there isn't more than one future coming of Christ) and both speak of believers being gathered to Christ while unbelievers are destroyed when Christ takes His vengeance on them.
