Here’s a theological poser: What happens to cannibals on Judgment Day? If I eat you and assimilate your flesh, how can we both be resurrected?
“It is not possible for two men to be resurrected with the same flesh at the same time, and nor is it possible for the same limb to have two different masters,” writes Athenagoras of Athens. “How can two bodies, which have successively been in possession of the same substance, appear in their entirety, without lacking a large part of themselves? In the end, either the disputed parts will be returned to their original owners, leaving a gap in the later owners, or they shall be fixed in the latter, leaving in this case an irreparable loss in the former.”
Augustine answers, “The flesh in question shall be restored to the man in whom it first became human flesh; for it is to be considered as borrowed of the other man, and, like borrowed money, to be returned to him from whom it was taken.”
I guess we’ll find out.
