The Catholic authorities are right to be cautious in equating incorruptibility with holiness; a case in point concerns the body of Cardinal Shuster (1880–1954), a former archbishop of Milan, which was discovered to be incorrupt after 31 years in the grave. The 1985 exhumation caused some embarrassment as the cardinal was anything but a saint; he was a friend of Mussolini and supported fascism and Italy’s war with Abyssinia. Nor does the phenomenon of incorrupt bodies necessarily prove the claims of Catholicism. When the famous yogi Paramahansa Yogananda died in California, in 1952, his unembalmed body had not decayed and was said to emit a beautiful fragrance. Perhaps there are many incorrupt bodies of holy Protestants, Jews, Muslims and Buddhists, but we’ll never know because these religions don’t have the unusual custom of digging up their suspected saints. [Editor’s note: There are, however, several incorrupt bodies of Buddhist monks which are preserved as objects of veneration. See **FT78:9, 157:23].
