The travelling missionary was as familiar a figure in the Levant as the travelling lecturer on philosophy. The Greek language brought all nationalities together. The Hellenising of the East had gone on steadily since the conquests of Alexander; and Greek was already as useful as Latin in many parts of the West. A century later, Marcus Aurelius wrote his Confessions in Greek; and even in the middle of the third century, when the tide was beginning to turn in favour of Latin, Plotinus lectured in Greek at Rome. Christianity, within a few years after the Crucifixion, had allied itself definitely with the speech, and therefore inevitably with the spirit, of Hellenism. At no time since have travel and trade been so free between the West of Europe and the West of Asia. A Phrygian merchant (according to the inscription on his tomb) made seventy-two journeys to Rome in the course of his business-life. The decomposition of nationalities, and the destruction of civic exclusiveness, led naturally to the formation of voluntary associations of all kinds, from religious sects to trade unions; sometimes a single association combined these two functions. The Oriental religions appealed strongly to the unprivileged classes, among which genuine religious faith was growing, while the official cults of the Roman Empire were unsatisfying in themselves and associated with tyranny. The attempt of Augustus to resuscitate the old religion was artificial and unfruitful. The living movement was towards a syncretism of religious ideas and practices, all of which came from the Eastern provinces and beyond them. The prominent features in this new devotion were the removal of the supreme Godhead from the world to a transcendental sphere; contempt for the world and ascetic abnegation of 'the flesh'; a longing for healing and redemption, and a close identification of salvation with individual immortality; and, finally, trust in sacraments ('mysteries,' in Greek) as indispensable means of grace or redemption. This was the Paganism with which Christianity had to reckon, as well as with the official cult and its guardians. The established church it conquered and destroyed; the living syncretistic beliefs it cleansed, simplified, and disciplined, but only absorbed by becoming itself a syncretistic religion. But besides Christians and Pagans, there were the Jews, dispersed over the whole Empire. There were at least a million in Egypt, a country which St. Paul, for reasons unknown to us, left severely alone; there were still more in Syria, and perhaps five millions in the whole Empire. In spite of the fecundity of Jewish women, so much emphasised by Seeck in his history of the Downfall of the Ancient World, it is impossible that the Hebrew stock should have multiplied to this extent. There must have been a very large number of converts, who were admitted, sometimes without circumcision, on their profession of monotheism and acceptance of the Jewish moral code. The
