I think that creates the strong probability it is bogus.
OK.
I don't know the details of the shroud and I really don't care. No doubt throughout his life thousands of scraps of cloth came in contact with Jesus so this is just one of them. But I like the point you made about God not wanting us to worship anything that is physical (yes, it's Biblical, from the Ten Commandments) but instead just worship the Word who became flesh.
Happy Resurrection Day, brother!
