The distinctive character of the rites in question lay in their appealing to the gloomy rather than to the cheerful and hopeful feelings, and in their influencing the mind through fear. The notions of guilt and expiation, of evil and good to come, and of dealings with the invisible world, were in some shape or other preëminent in them, and formed a striking contrast to the classical polytheism, which was gay and graceful, as was natural in a civilized age. The new rites, on the other hand, were secret; their doctrine was mysterious; their profession was a discipline, beginning in a formal initiation, manifested in an association, and exercised in privation and pain. They were from the nature of the case proselytizing societies, for they were rising into power; nor were they local, but vagrant, restless, intrusive, and encroaching. Their pretensions to supernatural knowledge brought them into easy connection with magic and astrology, which are as attractive to the wealthy and luxurious as the more vulgar superstitions to the populace. The Christian, being at first accounted a kind of Jew, was even on that score included in whatever odium, and whatever bad associations, attended on the Jewish name. But in a little time his independence of the rejected people was clearly understood, as even the persecutions show; and he stood upon his own ground. Still his character did not change in the eyes of the world; for favor or for reproach, he was still associated with the votaries of secret and magical rites. The emperor Hadrian, noted as he is for his inquisitive temper, and a partaker in so many mysteries, still believed that the Christians of Egypt allowed themselves in the worship of Serapis. They are brought into connection with the magic of Egypt in the history of what is commonly called the Thundering legion, so far as this, that the rain which relieved the Emperor's army in the field, and which the Church ascribed to the prayers of the Christian soldiers, is by Dio Cassius attributed to an Egyptian magician, who obtained it by invoking Mercury and other spirits. This war had been the occasion of one of the first recognitions which the State had conceded to the oriental rites, though statesmen and emperors, as private men, had long taken part in them. The emperor Marcus had been urged by his fears of the Marcomanni to resort to these foreign introductions, and is said to have employed Magi and Chaldæans in averting an unsuccessful issue of the war.
