Both cannot be true. The Council of Lyons:
“We believe in the true resurrection of this flesh that we now possess”
The apostle of Christ, Paul, 1 Cor. 15:44: “It is sown a a natural (physical) body, it is raised up a spiritual body”
Paul contrasts the physical body of flesh and blood with the spiritual body to be given and sums up in vs. 50,
“Flesh and blood cannot inherit God’s kingdom”.
Which shall it be? For me, Paul, not the Council.
“Both cannot be true.”
Yes they can. Sorry that you are confused by that basic truth.
The Fourth Lateran Council (1215), infallibly defined that at the second coming Jesus “will judge the living and the dead, to render to every person according to his works, both to the reprobate and to the elect. All of them will rise with their own bodies, which they now wear, so as to receive according to their deserts, whether these be good or bad [Rom. 2:6–11]” (constitution 1).
The righteous, they will be transformed into a glorified state, freed from suffering and pain, and enabled to do many of the amazing things Jesus could do with his glorified body (cf. 1 Cor. 15:35–44, 1 John 3:2).
