Just a thought on this...our "glorified", immortal, incorruptible, resurrected body will be ours in the sense that it will be the body we each will inhabit for eternity, but it cannot be our actual "physical body" merely because our mortal, human flesh bodies will return to dust. Not to mention, those whose bodies were incinerated by fires, cremation, bombs, etc. Therefore, we don't yet know what we shall be like only that our bodies will be like Jesus' glorified body and we shall see him as he is. We can eat, I hope, but it won't be to nourish our bodies in order to stay alive.
I know that our bodies turn to dust, get eaten by sharks, or worms, or just composted into a nice organic mix that later nourishes plant roots & fruits, turns into breakfast for some other people who eat those fruits over generations of time.
However, it's still the very same body that falls in death that will rise to be glorified. It's not a different body, but rather, our current body will rise and be glorified. We can't call it "resurrection" unless the soul returns to the same body, since resurrection is a second rising. The same that was buried, arises again, just as Our Lord's.
Jesus did not get a replica. He got his own body back, with even the wounds glorified.
If it were not the same body which the soul reclaims, it would not be a resurrection, but rather a reincarnation.
And the Bible does not teach reincarnation. It teaches the resurrection of the body.
St. Paul says our current bodies are like the seed. And just as a seed does not have all the qualities of the plant in mature form, but does have all these qualities in seed form, so too our body is linked to our resurrected body as its cause (a seed is the "cause" of a plant) and as its "selfness" (the seed grows into a plant which is its real self: it IS the plant, at a primitive level of development.)
Scripture says that the same body that dies will also rise. Job said, "And after my flesh has been destroyed, yet in my flesh I will see God; I myself will see him with my own eyes -—- I, and not another!"(Job 19:26-27).
And to the Apostles, shocked at his resurrection Jesus said, "Look at my hands and my feet. It is I myself! Touch me and see; a ghost does not have flesh and bones, as you see I have "(Luke 24:39).
So there is continuity. But there is also development and a shining forth of a new glory.
How God is going to collects all those boatbums molecules, I do not know! It's --- whew --- just so mind-boggling, isn't it? We'll see, won't we?!!
