St. Cyril, St. Ambrose, St. Augustine, and others of the early church fathers of note maintained that the relics of the saints had great efficacy in the cure of diseases. St. Augustine tells us: "Besides many other miracles, that Gamaliel in a dream revealed to a priest named Lacianus the place where the bones of St. Stephen were buried; that those bones being thus discovered, were brought to Hippo, the diocese of which St. Augustine was bishop; that they raised five persons to life; and that, although only a portion of the miraculous cures they effected had been registered, the certificates drawn up in two years in the diocese, and by the orders of the saint, were nearly seventy. In the adjoining diocese of Calama they were incomparably more numerous."[24] This great and intellectual man also mentions and evidently credits the story that some innkeeper of his time put a drug into cheese which changed travellers who partook of it into domestic animals, and he further asserts after a personal test that peacock's flesh will not decay. St. Ambrose declared that "the precepts of medicine are contrary to celestial science, watching, and prayer." When the conflict between St. Ambrose and the Arian Empress Justina was at its height, the former declared that it had been revealed to him that relics were buried in a certain spot which he indicated. When the earth was removed, there was exposed a tomb filled with blood, and containing two gigantic skeletons with their heads severed from their bodies. These were pronounced to be the remains of St. Gervasius and St. Protasius, two martyrs of gigantic physical proportions, who were said to have been beheaded about three centuries before. To prove beyond doubt the genuineness of these relics, a blind man was restored to sight by coming in contact with them, and demoniacs were also cured thereby. Before being exorcised, however, the demons, who were supposed to have supernatural and indubitable knowledge, declared that the relics were genuine; that St. Ambrose was the deadly enemy of hell; that the doctrine of the Trinity was true; and that those who rejected it would certainly be damned. To be sure that the testimony of the demons should have its proper weight in the controversy, on the following day St. Ambrose delivered an invective against all who questioned the miracle.[25]
