Basically, the claim is that Jesus’s rising from the dead circa 2,000 years ago happened much in the same way as his being spotted in potato chips today. The Daily Mail writes:
A sensational new theory about the Turin Shroud claims to destroy the core belief of Christianity – that Jesus Christ rose from the dead.
Art historian Thomas de Wesselow is convinced the Shroud is real and did touch Christ’s body. But the Cambridge academic insists that the image on the cloth fooled the Apostles into believing Christ had come back to life, and the Resurrection was in fact an optical illusion.
His theory is that in the mind of a person 2,000 years ago, the image on the Shroud would have been astonishing – far beyond their normal experiences and truly unsettling. ‘They saw the image on the cloth as the living double of Jesus,’ he said. ‘Back then images had a psychological presence, they were seen as part of a separate plain of existence, as having a life of their own.’
