I think Mary's assumption was a more recent infallible papal declaration, but I do not know on what it is based. ...... I agree with you that we will all have bodies for eternity.
The idea that we will have wings has absolutely no basis in Scripture or Tradition.
But what about poor Clarence? :)
Neither does the idea that we will become angels. Angels are created beings that are pure spirit and have no bodies (cf. Catechism of the Catholic Church 328330). They are a different order of being than we are, and humans and angels dont turn into each other.
Of this there can be no doubt.
Thanks for all the background on the imagery of Heaven. Some very good questions were raised, and I tended to agree with the answers.
Happy to help.
I’m pleased that we’re finding more common ground as we go on.
