Thus one observes how the supernatural manifestation, the miraculous event, was admitted and justified on principle in both the Neo-Platonic and the Christian system. In both, moreover, metaphysical or symbolizing tendencies had withdrawn attention from a close scrutiny of any fact, observed, imagined, or reported. With both, the primary value of historical or physical fact lay in its illumination of general convictions or accepted principles. And with both, the supernatural fact was the fact _par excellence_, in that it was the direct manifestation of the divine or spiritual power. Iamblicus had announced that man must not be incredulous as to superhuman beings and their supernatural doings. On the Christian side, there was no bit of popular credence in miracle or magic mystery, or any notion as to devils, angels, and departed saints, for which justification could not be found in the writings of the great Doctors of the Church. These learned and intellectual men evince different degrees of interest in such matters; but none stands altogether aloof, or denies _in toto_. No evidence is needed here. A broad illustration, however, lies in the fact that before the fourth century the chief Christian rites had become sacramental mysteries, necessarily miraculous in their nature and their efficacy. This was true of Baptism; it was more stupendously true of the Eucharist. Mystically, but none the less really, and above all inevitably, the bread and wine have miraculously become the body and the blood. The process, one may say, began with Origen; with Cyril of Jerusalem it is completed; Gregory of Nyssa regards it as a continuation of the verity of the Incarnation, and Chrysostom is with him.[49] One pauses to remark that the relationship between the pagan and Christian mysteries was not one of causal antecedence so much as one of analogous growth. A pollen of terms and concepts blew hither and thither, and effected a cross-fertilization of vigorously growing plants. The life-sap of the Christian mysteries, as with those of Mithra, was the passion for a symbolism of the unknown and the inexpressible. But one must not stop here. The whole Christian Church, as well as Porphyry and Iamblicus, accepted angels and devils, and recognized their intervention or interference in human affairs. Then displacing the local pagan divinities come the saints, and Mary above all. They are honoured, they are worshipped. Only an Augustine has some gentle warning to utter against carrying these matters to excess.
