An anticipation of the fire ordeal may be found in the Rabbinical story of Abraham when he was cast into a fiery furnace by Nimrod, for reproving the idolatry of the latter, and escaped unharmed from the flames;[969] as well as the similar experience of Shadrach, Mesach, and Abednego, when they were saved from the wrath of Nebuchadnezzar.[970] Miraculous interposition of this kind was expected as a matter of course by the early Christians. About the year 400 Rufinus, in his account of his visit to the monks of the Nitrian desert, tells an adventure of the hermit Copres as related to him by that holy man himself. On visiting a neighboring city he engaged in a disputation with a Manichæan who was perverting the people. Finding the heretic not easily overcome by argument, he proposed that a fire should be built in the public square, into which both should enter. The populace was delighted with the idea and speedily had a roaring pyre ready, when the Manichæan insisted that the Christian should enter first. Copres assented and remained unhurt in the flames for half an hour; his antagonist still held back, when the crowd seized him and tossed him into the fire, where he was severely scorched, and was ejected with disgrace from the city.[971] Almost identical is the story related in 597 A. D., under the Emperor Anastasius, of a Catholic bishop, who, after being worsted in a theological dispute by the subtle logic of an Arian, offered to test the soundness of their respective doctrines by together entering a blazing fire. The prudent Arian declined the proposition, when the enthusiastic Catholic jumped into the burning pile, and thence continued the controversy without suffering the least inconvenience.[972] In the less impressive form of filling the lap with burning coals and carrying them uninjured till they grew cold this ordeal seems to have been a favorite with holy men accused of unchastity. It is related of St. Brice, the successor of St. Martin in the see of Tours, of St. Simplicius of Autun, and of Montano bishop of Toledo in the sixth century.[973]
