As for the Shroud of Turin, the article states:
Pope Benedict XVI, visiting the Turin Shroud last year, did not address whether or not it was authentic, but spoke of its “intensity”: it was, he said, a symbol of the darkest, loneliest moments of Christ’s suffering, yet was also the brightest sign of hope.
There is plenty of debate in the comments and not much support for Nichols’s position. It makes for interesting reading at Debate: Does it matter if relics are fake? | CatholicHerald.co.uk
