The dead have already risen .
They certainly have not.
Act 1:9 And when he had said these things, as they were looking on, he was lifted up, and a cloud took him out of their sight.
Act 1:10 And while they were gazing into heaven as he went, behold, two men stood by them in white robes,
Act 1:11 and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.” (ESV)
1Th 4:14 For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep.
1Th 4:15 For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep.
1Th 4:16 For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God.
And the dead in Christ will rise first.
1Th 4:17 Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord. (ESV)
1Co 15:20 But in fact Christ has been raised from the dead,
the firstfruits of those who have fallen asleep.
1Co 15:21 For as by a man came death, by a man has come also the resurrection of the dead.
1Co 15:22 For as in Adam all die, so also in Christ
shall all be made alive.
1Co 15:23 But each in his own order:
Christ the firstfruits, then at his coming those who belong to Christ. (ESV)
1Co 15:52 in a moment, in the twinkling of an eye, at the last trumpet.
For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed. (ESV)
2Ti 2:15 Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.
2Ti 2:16 But avoid irreverent babble, for it will lead people into more and more ungodliness,
2Ti 2:17 and their talk will spread like gangrene. Among them are Hymenaeus and Philetus,
2Ti 2:18
who have swerved from the truth, saying that the resurrection has already happened. They are upsetting the faith of some.
Clearly this is speaking of a future event. Since Jesus has not returned, the resurrection of the dead has not happened. Notice in 2 Timothy, that not only is it explicitly stated that the resurrection had not happened, but that teaching that it has, is tied to "ungodliness" and swerving "from the truth," which is evidence that one is not "rightly handling the word of truth."
Not only that, nowhere in the NT is it even implied that the dead have been raised, despite numerous mentions of Jesus having been raised. The resurrection of everyone else is
always spoken of as a future event at the summation of all things when Christ returns.
Can't help you with Paul's writing's as he clearly indicates that we have two bodies .
Nowhere does Paul or any other writer in the entire Bible even suggest that we have two bodies.
1Co 15:42 So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable.
1Co 15:43 It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power.
1Co 15:44 It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body.
...
1Co 15:51 Behold! I tell you a mystery. We shall not all sleep, but we shall all be changed,
1Co 15:52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed.
1Co 15:53 For this perishable body must put on the imperishable, and this mortal body must put on immortality. (ESV)
We have one body which is sown perishable and mortal and then raised imperishable and immortal. One body, two different states. Just as the dead will at that time be raised imperishable, so too, will those who are alive "be changed" and also be made imperishable. Not a single word about a second body or removing of the flesh.
Do you think Christ returned to Heaven in a flesh body?
Isn't that what I said: "He is still truly God and truly man, with his "spiritualized," physical resurrection body"? Our bodies will be like Christ's--physical, yet somehow changed to be imperishable, immortal. He will return from heaven in the same way he went up. There is nothing in the entirety of the NT which states Jesus somehow lost his physical body prior to, or after, returning to heaven. To suggest such a thing would be mere speculation.
