I get thrown the miracle of the shroud of Turin on a regular basis — just last week someone confronted me with it, basically saying “A-ha! Jesus existed because there’s an old scrap of cloth with a face on it!” It doesn’t matter that I point out that it’s been dated to the 13th century, and was nothing more than a profit-making ‘relic’ for churches that would also hawk Jesus’s foreskin and John the Baptist’s pinky bone. They’d usually retort that it was not humanly possible to make the shroud, so it had to be a religious miracle.
Now I’ve got more ammo. The Shroud of Turin has been recreated, using simple medieval technologies. No magic, just acidic pigments.
I know, it won’t stop the kooks, but it’s still useful to know. Next up, we need more evidence against the patently goofy Miracle of Luciano, which is the other ‘proof’ of god that gets flung around a lot.
