lower purlieus of the system, filled in by accepting current superstitions, was there any contact with something like vital religious forces. But those minor elements—hopes and fears about another world, fasts and penances, ecstasies and marvels—had no necessary relation to that metaphysical system. Such practices could be found in every religion, in every philosophical sect of the time. The Alexandrian dialectic of the supernatural accordingly remained a mere schema or skeleton, to be filled in with the materials of some real religion, if such a religion should arise. As such a schema the Neo-Platonic system actually passed over to Christian theology, furnishing the latter with its categories, its language, and its speculative method. But that dialectic served in Christianity to give form to a religious substance furnished by Hebrew and apostolic tradition, a religious substance such as, after the Pagan religion was discredited, Neo-Platonism necessarily lacked and was powerless to generate. We have mentioned apostolic tradition. It is fortunately not requisite for our purpose to discuss the origin of this tradition, much less to decide how much of what the Christian Church eventually taught might be traced to its Founder. That is a point which even the most thorough scholars seem still to decide mainly by their prejudices, perhaps because other material is lacking on which to base a decision. For our present object we may admit the most extreme hypotheses as equally possible. The whole body of Catholic doctrine may have been contained in the oral teaching of Christ; or, on the other hand, a historical Jesus may not have existed at all, or may have been one among many obscure Jewish revolutionists, the one who, by accident, came afterward to be regarded as the initiator of a movement to which all sorts of forces contributed, and with which he had really had nothing to do. In either case the fact remains which alone interests us here; that after three or four centuries of confused struggles, an institution emerged which called itself the Catholic Church. This church, possessed of a recognized hierarchy and a recognized dogma, triumphed, both over the ancient religion, which it called Paganism, and over its many collateral rivals, which it called heresies. Why did it triumph? What was there in its novel dogma and practice that enchained the minds that Paganism could retain no longer, and that would not be content with Neo-Platonism, native, philosophical, and pliable as that system was? The answer, to be adequate, would have to be long; but perhaps we may indicate the spirit in which it ought to be conceived. Paganism was a religion,
