The Shroud of Turin is one of the great enduring mysteries of all time, with its authenticity debated for years. Many believe it's the burial cloth of Jesus and the only physical link to Him, while others maintain that it is nothing more than an elaborate hoax. In fact, in 1988, a team of scientists radiocarbon dated the Shroud and concluded it was fake, dating back to the Middle Ages (1290-1360), long after Jesus was crucified. And that's where the story stood, unchallenged -- until now.
