Admit your problem.
Part of your problem is you are not well-read on this subject, and you can’t ever express an educated opinion because you wouldn’t “contaminate” yourself by reading about it. Sad.
I’d find another thread if I were you — you’re wasting your time and our time.
“Anti-Catholicism, pure and simple.”
The Roman Catholic Church doesn’t even take a position on the shroud. Not remotely relevant to the discussion.
