The Shroud is not central to my faith so it doesn’t matter to me either way. If the science says it’s not authentic, it doesn’t bother me because I still believe in Christ every bit as much but if it is somehow proven authentic, all the greater glory to God.
I’m pretty much in agreement with you, here. I think I’d be pleased to learn it was genuine but don’t put any store in relics, so if it were not genuine my faith would not be affected one way or the other.
