I believe Jesus resurrected in the same body as he had before he died. I am not convinced he ascended into heaven with that same body. Maybe his flesh body dematerialized during the ascension (just my speculation)
Do you believe Angels have flesh bodies? Did they not appear before Abraham as flesh men and did eat and drink?
Gen 18:2 And he lift up his eyes and looked, and, lo, three MEN stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
Gen 18:8 And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.
Gen 19:3 And he pressed upon them greatly; and they turned in unto him, and entered into his house; and he made them a feast, and did bake unleavened bread, and they did eat.
Gen 19:5 And they called unto Lot, and said unto him, Where are the MEN which came in to thee this night? bring them out unto us, that we may know them.
So what kind of bodies did these Angels have before they appeared to Abraham on earth? What kind of bodies did they have when they returned to heaven? Did they leave a flesh body behind? Did it "change" in the twinkling of an eye as they went back to heaven? Did Jesus's body change in the twinkling of an eye when he ascended back to heaven after his resurrection?
Does that mean Christ doesn't have a body now? Of course not. I believe he does have a body and so do the Angels but it is not of flesh imo.
1Co 15:52 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.
