Such comparisons, however, had a very different side. Greece had long had its secret mysteries, with their sacred initiations, their rites of purity and enlightenment, their promises of welfare beyond the grave. When the new deities from Asia Minor, from Egypt, Syria, and the further East, were brought to Italy, the resemblances of their practice to that of the Christian Church excited the {52} believer's alarm, and roused at once the charge of plagiarism. There was a congregation of Mithra at Rome as early as 67 B.C., and towards the end of the first century of our era his mysteries began to be widely spread. Here was a baptism; here was a "sacrament" as the neophyte took the oath on entering the warfare with evil; here were grades of soldiership and service; here were oblations of bread and water mingled with wine which were naturally compared with the Lord's supper; here were doctrines of deliverance from sin, of judgment after death and ascent to heaven, which brought the theology and practice of Mithraism very close to that of the Church. So Mithra bore the august titles of the holy and righteous God; or he was the Mediator, author of order in nature and of victory in life between the ultimate powers of good and evil. For a time the rivalry was acute, as his worship was carried through the West as far as York and Chester and the Tyne. But with the triumph of Christianity in the fourth century the sounds of conflict die away. The men of learning, Eusebius of Cæsarea (about A.D. 260-340), Augustine (A.D. 354-430) bishop of Hippo, surveyed the religions and philosophies of antiquity as conquerors. The faiths of Egypt, Phœnicia, Greece, and Rome, are passed in review. With a broad sweep of learning Eusebius comments on the ancient mythologies, the oracles, the theory of demons, {53} the practice of human sacrifice, the history of Mosaism. His treatise on the "Preparation for the Gospel" is the first great work on comparative religion which issued out of Christian theology. With generous recognition of what lay beyond the Church he taught (in the _Theophania_) that all higher culture was due to participation in the Logos. Idolatry might be the work of demons; the world might be filled with the babblings of philosophers and the follies of poets; but the Logos had been continuously present, sowing in the hearts of men the rudiments of the divine laws, of various orders of teaching, of doctrines of every kind. Thus ethics, art, science, and the fairest products of human thought, were genially brought within the scope of Revelation. II
