I’ve been reading up about transubstantiation and came upon a very old thread where Lanciano and the Shroud were also mentioned and how all (most)? of the miracles are type AB blood. The poster mentioned something I’ve never heard before, that some believe that when blood ages it can turn to type AB.
If the blood types are naturally occurring that is one less thing pointing to miracles.
I emailed a doctor and asked if old blood can turn to AB. And he said it "possibly. True but there is no scientific consensus among all scientists, nor do they know how many years it would take for all blood types to transition to AB.
Does anyone here. Know anything about this?
