And that's exactly what Paul says happens for the saints in heaven when they resurrect into new bodies that were in heaven for them. All they have to wait for is time for that bodily resurrection. Have any scriptures that say the dead in Christ resurrect back into their dead bodies on Earth? I can't find anything. Only the unsaved return to their bodies...
You are assuming Paul is talking about resurrection as opposed to rapture (resurrection plus rapture.) The passage talks about being clothed with something heavenly.
Look at the words again:
II Corinthians 5
1 For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.
2 For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven:
3 If so be that being clothed we shall not be found naked.
4 For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.
Paul speaks of putting something on, something from heaven. He does not talk about a new version of himself being created. If the rapture happens, this heavenly dwelling will cloth him, not replace him. It is the same for the resurrection.
These verses from I Corinthians 15 contradict your viewpoint:
35 But some man will say, How are the dead raised up? and with what body do they come?
36 Thou fool, that which thou sowest is not quickened, except it die:
It dies, then is quickened-- which means comes to life, ζωοποιεῖται.
This also disproves your argument:
42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
You have two separate bodies.
49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
II Corinthians 5 speaks of being clothed with the house from heaven. Here is a reference to bearing the heavenly image.
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
See in verse 52, the dead are raised incorruptable. The dead stand up again, but incorruptable. Their body is not replaced with a superior version in heaven. The dead are raised, instead. The bodies of those who remain are transformed, changed-- not replaced with another body.
But we put something on. We put on the heavenly image, immortality.
From a historical creedal perspective, your view would be considered heresy since the Apostles Creed includes a profession of belief in the resurrection of the body.
