You're clearly only interested in what Paul said in his first epistle to the Thessalonians, so let's just read it together and see what it actually says.
1 Thessalonians 4
13But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
14For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
15For 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.
16For 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:
17Then 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.
18Wherefore comfort one another with these words.
Here, Paul is talking to the Thessalonian saints about Christians who are asleep or have died in Christ, and how they ought not to feel sorrow for them as with others who have no hope after death apart from Christ. He then goes on to explain how that Jesus will bring with him those who are asleep in him at the coming of the Lord.
Well, where is Jesus coming from?
He's coming from the third heaven (2 Corinthians 12:2) where he presently dwells, and the dead in Christ presently dwell there too because to be absent from the body is to be present with the Lord (2 Corinthians 5:8). When Jesus and the dead in Christ come and descend from the third heaven, the Christians who yet are alive and remain on this earth will not prevent or precede those who are asleep, or they will not get their resurrected and glorified bodies ahead of those who Christ is coming and descending with from the third heaven. Not only this, but the Christians who are yet alive and who yet remain on the earth at that time will meet both the Lord and the dead in Christ in the clouds, which are a part of this earth's atmosphere, or in the air, which is part of this earth's atmosphere, or which are part of what we might rightly call the first heaven (Genesis 1:20). I mean, if there's a third heaven, then logic dictates that there must also be a first and second heaven, and the first heaven is where the clouds exist.
With these things in mind, how in the world do you see this as some sort of rapture to the third heaven?
In other words, where's the about face back to the third heaven?
In reality, it's nowhere to be found in the text because it's an outright lie from the father of lies. Anybody who reads this portion of scripture honestly can see that there's no mention of any return to the third heaven in it anywhere. That has to be forced upon the text because of somebody's prior beliefs that they were indoctrinated into believing. The only people being raptured or caught up here are the saints who will yet be alive while remaining on this earth at the Lord's coming and descending with his saints to this earth from the third heaven, and they are caught up to meet them in the air or in the clouds in their coming and descent in the first heaven. Again, no returning back to the third heaven or ascension back to the third heaven is mentioned anywhere in the text.
If you or anybody else honestly can't see this, then I'm very worried about you.
You said that no other disputed verses were needed here, so let's see what you do with this one. Hopefully, you'll embrace it for what it actually says.
