I would be more careful presenting something and claiming it to be other than it is in the hope that people will put their faith in it rather than in God. Scripture doesn't say "here is the shroud. in it I am well pleased." How much damage has been done throughout history by getting people to put their faith in things later proven to be pious frauds. Let the evidence speak. If it's a fraud, it's a fraud. If it's real, it's real. But the weight of evidence should tell - not a wink and a hardy "trust me."
