In the end the question is easy.
Are you expecting the return of the same Flesh Jesus of 2000 years ago?
This is an oft-asked question when discussing physical resurrection, and of course we cannot know with absolute certainty the state of affairs until they unfold, but Scripture itself offers a path to answers if one contemplates the text.
The first clue is in the post-Resurrection appearance to Mary Magdalene:
"When she had thus said, she turned herself back, and saw Jesus standing;
and she knew not that it was Jesus. Jesus saith to her: Woman, why weepest thou? whom seekest thou? She, thinking it was the gardener, saith to him: Sir, if thou hast taken him hence, tell me where thou hast laid him, and I will take him away. Jesus saith to her: Mary. She turning, saith to him: Rabboni (which is to say, Master). (John 20:14-16)
Another is the appearance to the two disciples on the road to Emmaus:
"And it came to pass, that while they talked and reasoned with themselves, Jesus himself also drawing near, went with them.
But their eyes were held, that they should not know him... Cleophas, answering, said to him: Art thou only a stranger to Jerusalem, and hast not known the things that have been done there in these days?" (Luke 24:15-18)
They tell Him, and He explains the events to them, but still they are unaware until:
"And it came to pass, whilst he was at table with them, he took bread, and blessed, and brake, and gave to them.
And their eyes were opened, and they knew him: and he vanished out of their sight." (Luke 24:30-31)
In John 20:19-25 we have the account of His physical presence in a locked room, but close attention to verse 20: "he shewed them his hands and his side. The disciples therefore were glad, when they saw the Lord." Later He appears among them again, and addresses Thomas: "Then he saith to Thomas: Put in thy finger hither, and see my hands; and bring hither thy hand, and put it into my side; and be not faithless, but believing. Thomas answered, and said to him: My Lord, and my God." (v27-28)
And again: "... Jesus stood on the shore: yet the disciples knew not that it was Jesus. Jesus therefore said to them: Children, have you any meat? They answered him: No..." (John 21:4-5)
Again and again, Christ is at first not recognised, and then is. With the Magdalene, it's when he calls Her by name; With the disciples on the road, it's when He celebrates a Eucharist; With the disciples, it's when He shows them His wounds.
Jean Borella says it best:
The Spirit dwells in the world, but the world is less real and less perfect than the Spirit. At the very least there is a degree of the world — precisely the one which we are experiencing — whose imperfection crushes us and leads to death.
To be seen, and to be corporeally present, is all one. My corporeal presence is my visibility, but my visibility is not my own; it belongs to every gaze, unbeknownst to me and without being able to do anything about it — an ignorance and impotence constituting the every essence of my visibility. Thus, no one is master of his corporeal presence, and, even more, to be corporeally present is not to be master of this presence.
(After the Resurrection) Christ's body is still the instrument of presence in the world of bodies, but, by a total change, it is no longer of the essence of this presence to be passive and involuntary. The soul which inhabits this instrument is entirely master of it and makes use of it at will. Christ can actualize the corporeal mode of His presence according to His own decision and as He judges good. The relationship that He entertains with the corporeal medium of His presence has been completely transformed.
Christ is no longer seen, He causes Himself to be seen. This is exactly what the Gospels teach, and which so many modern exegetes are incapable of understanding. Christ glorious is not 'above' the world of the senses, except in a symbolic sense. Simply put, He is no longer subject to the conditions of this corporeal world. His bodily presentification becomes, then, a simple prolongation of its spiritual reality, entirely dependent upon this reality (whereas in the state of fallen nature, it is the person's spiritual reality which extrinsically dependent upon its bodily presence), a presentification which the spiritual person may or may not effectuate, as freely as human thought can, in its ordinary state, produce or not produce such or such a concept or sentiment.
