I find it interesting that without exception, the doubters and their arguments have not read the scientific, forensic, historical and biological records. Read "The Shroud and the Blood" by Ian Wilson. He answers every argument with facts from all these disciplines. As for worshipping a relic, I know of no Christian who would worship the shroud. But could not God's hand be in the recent advances in science and the revived interest in the shroud? Maybe there are some Thomases who need to put their hand in the wounds.
