Beyond the borders of Palestine, where they held their ancient glories in perpetual remembrance, the Jews gave less thought to their Messiah. In the Greek cities whither they had been allured by commerce, at Ephesus, Cyrene, and above all, Alexandria, they tried to gain acceptance for their traditions and their monotheism under the warranty of the Sibyls; they composed apocryphal writings in somewhat tame verse, or studied Greek philosophy. The monistic theories of Plato attracted them most strongly to his school, and Philo makes amazing efforts, by dint of moral allegorising, to discover Platonic teachings in Genesis. The word, λόγος, which signifies both the reason of things and human speech, became the starting point of a kind of abstract mythology; and among the Hellenistic Jews the idea of the Word assumed an importance equal to, and a character hardly less personal than, that of the Messiah among the Jews of Palestine. From one of these groups Christian legend was destined to arise, from the other Christian philosophy. The Persian doctrine of the principle of evil, the Egyptian doctrine of the resurrection of the body, had already become familiar to the Jews; Christianity adopted them and made them the basis of a vast mythological edifice, the Fall and Redemption, the great Judgment Day of God, and the coming of His kingdom upon earth after the destruction of the world, which was placed in the immediate future. The dispersion of the Jews throughout all the eastern provinces of the empire offered a vast field to Christian propaganda, which, however, soon spread beyond the Jewish race, when once the innovating party had definitely rejected circumcision, the distinction between clean and unclean meats, and all the trivial and troublesome practices which separated Israel from other nations. The Jewish element was soon submerged by the rising tide of world-wide proselytism known as the calling of the Gentiles.
