Mystery religions and Christianity

Christianity originated during the time of the Roman Empire, which was also the time at which the mysteries reached their height of popularity. This was by no means an accident. The Christian theologian Origen wrote in the 3rd century that it was part of the divine plan that Christ was born under the emperor Augustus: the whole Mediterranean world was united by the Romans, and the conditions for missionary work were more favourable than ever before. The simultaneousness of the propagation of the mystery religions and of Christianity and the striking similarities between them, however, demand some explanation of their relationship. The hypothesis of a mutual dependence has been proposed by scholars—especially a dependence of Christianity upon the mysteries—but such theories have been discarded. The similarities must rather be explained by parallel developments from similar origins. In both cases, national religions of a ritualistic type were transformed, and the transformation followed similar lines: from national to ecumenical religion, from ritualistic ceremonies and taboos to spiritual doctrines set down in books, from the idea of inherited tradition to the idea of revelation. The parallel development was fostered by the new conditions prevailing in the Roman Empire, in which the old political units were dissolved, and the whole civilized world was ruled by one monarch. People were free to move from one country to another and became cosmopolitan. The ideas of Greek philosophy penetrated everywhere in this society. Thus, under identical conditions, new forms of religious communities sprang from similar roots. The mystery religions and Christianity had many similar features—e.g., a time of preparation before initiation and periods of fasting; baptism and banquets; vigils and early-morning ceremonies; pilgrimages and new names for the initiates. The purity demanded in the worship of Sol and in the Chaldean fire rites was similar to Christian standards. The first Christian communities resembled the mystery communities in big cities and seaports by providing social security and the feeling of brotherhood. In the Christian congregations of the first two centuries, the variety of rites and creeds was almost as great as in the mystery communities; few of the early Christian congregations could have been called orthodox according to later standards. The date of Christmas was purposely fixed on December 25 to push into the background the great festival of the sun god, and Epiphany on January 6 to supplant an Egyptian festival of the same day. The Easter ceremonies rivalled the pagan spring festivals. The religious art of the Christians continued the pagan art of the preceding generations. The Christian representations of the Madonna and child are clearly the continuation of the representations of Isis and her son suckling her breast. The statue of the Good Shepherd carrying his lost sheep and the pastoral themes on Christian sarcophagi were also taken over from pagan craftsmanship.

In theology the differences between early Christians, Gnostics (members—often Christian—of dualistic sects of the 2nd century ad), and pagan Hermetists were slight. In the large Gnostic library discovered at NajʿḤammādī, in upper Egypt, in 1945, Hermetic writings were found sideby-side with Christian Gnostic texts. The doctrine of the soul taught in Gnostic communities was almost identical to that taught in the mysteries: the soul emanated from the Father, fell into the body, and had to return to its former home. The Greeks interpreted the national religions of the Greek Orient chiefly in terms of Plato’s philosophical and religious concepts. Interpretation in Platonic concepts was also the means by which the Judeo-Christian set of creeds was thoroughly assimilated to Greek ideas by the early Christian thinkers Clement of Alexandria and Origen. Thus, the religions had a common conceptual framework. The doctrinal similarity is exemplified in the case of the pagan writer and philosopher Synesius. The people of Cyrene selected him as the most able man of the city to be their bishop, and he was able to accept the election without sacrificing his intellectual honesty. In his pagan period he wrote hymns that closely follow the fire theology of the Chaldean Oracles; later he wrote hymns to Christ. The doctrine is almost identical.

The similarity of the religious vocabulary is also great. Greek life was characterized by such things as democratic institutions, seafaring, gymnasium and athletic games, theatre, and philosophy. The mystery religions adopted many expressions from these domains: they spoke of the assembly (ekklēsia) of the mystai; the voyage of life; the ship, the anchor, and the port of religion; and the wreath of the initiate; life was a stage and man the actor. The Christians took over the entire terminology; but many pagan words were strangely twisted in order to fit into the Christian world: the service of the state (leitourgia) became the ritual, or liturgy, of the church; the decree of the assembly and the opinions of the philosophers (dogma) became the fixed doctrine of Christianity; the correct opinion (orthē doxa) about things became orthodoxy.

There are also great differences between Christianity and the mysteries. Mystery religions, as a rule, can be traced back to tribal origins, Christianity to a historical person. The holy stories of the mysteries were myths; the Gospels of the New Testament, however, relate historical events. The books that the mystery communities used in Roman times cannot possibly be compared to the New Testament. The essential features of Christianity were fixed once and for all in this book; the mystery doctrines, however, always remained in a much greater state of fluidity. The theology of the mysteries was developed to a far lesser degree than the Christian theology. There are no parallels in Christianity to the sexual rites in the Dionysiac and Isiac religion, with the exception of a few aberrant Gnostic communities. The cult of rulers in the manner of the imperial mysteries was impossible in Jewish and Christian worship.

The mysteries declined quickly when the emperor Constantine raised Christianity to the status of the state religion. After a short period of toleration, the pagan religions were prohibited. The property of the pagan gods was confiscated, and the temples were destroyed. The precious metal used to coin Constantine’s gold pieces was taken from heathen temple treasuries. To show the beginning of a new era, the capital of the empire was transferred to the new Christian city of Constantinople. The centres of pagan resistance were Rome, where the old aristocracy clung to the mysteries, and Alexandria, where the pagan Neoplatonist philosophers expounded the mystery doctrines. When Julian the Apostate, Roman emperor from ad 361 to 363, tried to reestablish pagan worship, he found allies at Rome and Alexandria. After his death, the pagan opposition to Christianity continued for one more generation. The Roman aristocrats multiplied their efforts to maintain the piety of the mysteries, and the pagan philosophers tried to refine their theology by oversubtle interpretations. In 391, however, the Serapeum at Alexandria was demolished, and in 394 the opposition of the Roman aristocracy was crushed in battle at the Frigidus River (now called the Vipacco River in Italy and the Vipava in Slovenia).

Only remnants of the mystery doctrines, amalgamated with Platonism, were transmitted by a few philosophers and individualists to the religious thinkers of the Byzantine Empire. The mystery religions exerted some influence on the thinkers of the Middle Ages and the philosophers of the Italian Renaissance.
