Mother Teresa of Calcutta was tormented by doubts about her faith and for decades privately suspected that religion was "a fetid mountain of horse manure", it has emerged in a newly published book of her letters. Shortly after beginning her work in the slums of Calcutta, she wrote “Where is my faith? It is just so much festering cock and balls, nothing but toxic mumbo jumbo." The letters reveal that for the last nearly half-century of her life she felt no presence of God whatsoever, however the Catholic Church says we shouldn't get the wrong idea. "Many believers get the silent treatment from God," said Pope Benedict this week. "It's just His way of saying hi."
