John Moore, A View of Society and Manners in Italy…
“ That all justice may be done, and that Satan may have his due, an advocate is employed to plead against the pretensions of the Saint Expectant, and the person thus employed is denominated by the people, the Devil’s Advocate. He calls in question the miracles said to have been wrought by the Saint and his bones, and raises as many objections to the proofs brought of the purity of his life and conversation as he can. ”
