In an interview with an Italian magazine, Diva e Donna, Father Cardin said: "The Holy Shroud was moved in secret to the sanctuary in the Campania region on the precise orders of the House of Savoy and the Vatican.
"Officially this was to protect it from possible bombing (in Turin). In reality, it was moved to hide it from Hitler who was apparently obsessed by it. When he visited Italy in 1938, top-ranking Nazi aides asked unusual and insistent questions about the Shroud."
Father Cardin, a Benedictine monk, said that after Italy entered the war in alliance with Hitler, and German forces were sent to Italy, the shroud was very nearly discovered in its secret hiding place.
We're lucky that the Catholic Church spent so much time and energy keeping a stained tablecloth from falling into Nazi hands. There wasn't anything else they could have been doing during World War II, after all.
