I don't disagree. We have a remembrance of Christ's sacrifice--the Lord's supper--and Paul says that "as often as [we] eat this bread and drink the cup, [we] proclaim the Lord's death until he comes" (1 Cor. 11:26). The implication of "until he comes" is that when Christ is here in the flesh, there is no longer any need for the remembrance.
That's my beef with Dispesnationalists who claim that the Temple and sacrifices are to be restored as a memorial in the Millennium. Again, what need is there to memorialize the living and eternal ruler sitting on a throne there in Jerusalem?
So as not to derail your original question too far, it seems to me that Christ remaining in his human body--the same one--is part and parcel with his work as mediator and intercessor. The work of the Atonement is complete (Heb. 1:3), but his work as mediator continues. Christ is God and man because in that work, he represents both God and men; and since the intercessory work goes on, the incarnation did not cease at the ascension.
The hope of the Christian is the resurrection of the body, not the escape from the body, and it also seems to me, not a new body: restored, perhaps, but not a different body than the present one, which strikes me as more in line with the Greek philosophy of transmigration than the Christian view of resurrection. And that means that if Christ is the firstfruits of the resurrection, then he, too, is in the same flesh that he had on earth. And if his wounds are there as a testament to his sacrifice on the cross, then it stands to reason they also remain "yet visible above."
