I think I can clearly prove that the Shroud of Turin does not depict Jesus. The Bible says in
Isaiah 52 and 53 that Jesus was tortured so hard that he no longer looked like a human being. The Bible even goes so far as to say that no human being has ever been so disfigured. He was so disfigured that people could not even look at him. The Romans used a whip with small pointed bones attached to the ends that pulled out his skin. Jesus said in the OT that he sees his bones because he lost a lot of flesh during the torture and he said that they pulled out his beard. He was completely disfigured. So the man on the Shroud of Turin cannot be Jesus because he looks quite like a human being, he is not disfigured.
First you'd have to prove that Isaiah is speaking about Jesus. I suspect that would be a difficult task for a number of reasons, one being that the name Jesus isn't ever mentioned in Isaiah, and another being that that would be ignoring the entire context of Isaiah. The other problem I see with this interpretation is that it flies in face of Mark 16:1 which says:
" When the Sabbath was over, Mary Magdalene, Mary the mother of James, and Salome bought spices so that they might go to anoint Jesus’ body."
Spices were put on pre-buried bodies to cancel out the smell of the rotting corpse. Doing it to an already buried body, three days after the burial, was redundant. More so if Jesus's body had been so terribly disfigured from injuries: it's likely that it would have needed an enormous amount of spices to counter the smell. Remembering to do it three days after burial was pointless. It's also disrespectful to the dead body to manhandle it post-burial, and let's not forget that these women were still Jewish, following Jewish burial customs.
