The most curious record of sudden conversion with which I am acquainted is that of M. Alphonse Ratisbonne, a freethinking French Jew, to Catholicism, at Rome in 1842. In a letter to a clerical friend, written a few months later, the convert gives a palpitating account of the circumstances.(121) The predisposing conditions appear to have been slight. He had an elder brother who had been converted and was a Catholic priest. He was himself irreligious, and nourished an antipathy to the apostate brother and generally to his “cloth.” Finding himself at Rome in his twenty‐ninth year, he fell in with a French gentleman who tried to make a proselyte of him, but who succeeded no farther after two or three conversations than to get him to hang (half jocosely) a religious medal round his neck, and to accept and read a copy of a short prayer to the Virgin. M. Ratisbonne represents his own part in the conversations as having been of a light and chaffing order; but he notes the fact that for some days he was unable to banish the words of the prayer from his mind, and that the night before the crisis he had a sort of nightmare, in the imagery of which a black cross with no Christ upon it figured. Nevertheless, until noon of the next day he was free in mind and spent the time in trivial conversations. I now give his own words. “If at this time any one had accosted me, saying: ‘Alphonse, in a quarter of an hour you shall be adoring Jesus Christ as your God and Saviour; you shall lie prostrate with your face upon the ground in a humble church; you shall be smiting your breast at the foot of a priest; you shall pass the carnival in a college of Jesuits to prepare yourself to receive baptism, ready to give your life for the Catholic faith; you shall renounce the world and its pomps and pleasures; renounce your fortune, your hopes, and if need be, your betrothed; the affections of your family, the esteem of your friends, and your attachment to the Jewish people; you shall have no other aspiration than to follow Christ and bear his cross till death;’—if, I say, a prophet had come to me with such a prediction, I should have judged that only one person could be more mad than he,—whosoever, namely, might believe in the possibility of such senseless folly becoming true. And yet that folly is at present my only wisdom, my sole happiness.
