Supernatural protection sure would be nice for any holy relic. If that were so we’d still have the cross Jesus was crucified on and many other things. Some of the things that have happen to the Shroud; it was damaged in a fire, has water damage, and smoke damage. Just some general information, there is a really big business in relics, going all the way back to the medival times and further. Even today, ancient items are a big business and also a blackmarket business that goes into the millions of dollars. As a side item, the History channel has an excellent show on the Shroud of Turin and does an excellent job of presenting both sides. The show concludes with…actually you should watch it!
God Bless you and keep you safe from all harm
