so someone has claimed to have found the blood of jesus. how do you tell its jesus blood. im no experct in these matters,but in order to tell what blood belongs to who,dont you need other blood to compare it to? how does he know its the blood of jesus? did it turn water into wine? instead of testing this blood,perhaps he should have tests done on his head.
