Isa 40:6 The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:
Isa 40:7 The grass withereth, the flower fadeth: because the spirit of the LORD bloweth upon it: surely the people is grass.
Isa 40:8 The grass withereth, the flower fadeth: but the word of our God shall stand for ever.
So what does God say about the matter??? Yor religion doesn't bother to consider what God has said, about any thing...
Our body is a shell...It hold us, It holds how we are; a living spirit and soul...
Our flesh will die and rot...UNTIL, God pulls it back together and our flesh is glorified into a heavenly body...
Obviously, Jesus had the same experience...Hid body died, Jesus body was glorified for the trip and residence in heaven...
We are created in the image of God...
Who cares what Nestor or any one of your popes say??? What does God say???
"Thou shalt not bear false witness"
Language matters, so one doesn't fall into heresy. It's pretty clear from Scripture that Our Lord Jesus Christ was one Person with two natures, human and divine. You are correct that He had a body that was subject to death during His earthly life, but His resurrected body is a glorified body.
