It’s not only weak it’s adding to scripture.
Did metmom add to Scripture when she said that Moses; soul went to heaven and God gave him a new body to return to earth?
And for the record....
I did not add to Scripture since I did not make the claim or say that Scripture specifically tells us what happened to Moses’ body after he was buried.
I came to a belief about it based on what Scripture says, i.e. God has assumed at least two others into heaven, God would not conjure up a ghost and Moses appears with Jesus at the Transfiguration along with Elijah, who is one that we know God has taken into heaven.
Basing a belief on what Scripture tells us in a specific case and then seeing how that belief and understanding applies to ourselves personally and humanity in general is not adding to Scripture.
