Hahaha i can't help but laugh... Its most likely fake...
Jews don't keep their foreskins preserved in jars as far as i know, do they? Would Mary or Joseph want to keep it as a memento?
18 claimed Holy Foreskins hey... LoL... I know there been heaps
Its been the subject of much speculation in the past. Would the foreskin have risen up to heaven as well???
Well...
17th century theologian Leo Allatius said that Christs foreskin had ascended into heaven to become the rings of Saturn
Oh man... Imagine it is actually true...
That still cracks me up but it was taken seriously at the time. There were too many claimed foreskins in circulation so they tried to wipe the floor with them all using that theory... Look into it M_Y... The rings of Saturn
