1. In its relation to the stories of current mythology, the Virgin Birth was a subject of active discussion in the time of the fathers. The patristic apologists make two points in referring to the mythological parallels. On the one hand, the similarity of the Gospel story in its supernatural element to the stories prevalent at the time is appealed to in order to commend it to the acceptance of the Greeks. Thus Justin says: "We propound nothing different from what you believe regarding those whom you esteem sons of Jupiter."[218] Similarly Origen says: "There is no absurdity in employing Grecian histories to answer Greeks with a view to showing that we are not the only persons who have recourse to miraculous narratives of this kind."[219] On the other hand, the difference between the Christian and the heathen stories is appealed to as proof of the moral and historical superiority of the Gospel narratives. Justin says that the Virgin conceived "not by intercourse but by power;"[220] and Origen, referring to a tradition about the birth of Plato, says that such stories are "veritable fables."[221] 218: "Apol.," I, 21. 219: "Contra Cels.," I, 37. 220: "Apol.," I, 33. 221: "Contra Cels.," I, 37. The notion is popular to-day that stories of the birth of a god or a hero from a virgin are common in non-Christian religions, and the remark is heard that the Virgin Birth of Jesus would be credible were it not for these parallels. A closer examination shows, however, that while supernatural births were the common property of most ancient religions, the Virgin Birth was a distinctive and spontaneous feature of Christianity. Thus Clemen remarks that "what we find in Indian thought (at any rate in earlier times) is not a Virgin Birth in the proper sense of that term, but only a miraculous birth, and one of quite a different type from the birth of Jesus."[222] Alluding to the fact that Buddhism was so entirely outside the western range of vision as to be noticed very meagrely in the Greek and Roman literature, Clemen says that "if there are similarities that cannot be accidental between this later Buddhistic literature and the New Testament, the question would arise whether the former could not be dependent upon the latter,"[223] since Christianity penetrated early to India. 222: "Primitive Christianity," pp. 294, 295. Clemen would himself trace the idea of the Virgin Birth to a passage in Philo ("De. Cher." 13 f.) in which the wives of the Patriarchs represent virtues (p. 297). 223: _Ibid._, p. 37.
