This transformation of religion into a philosophic system would not have been possible had not Greek philosophy itself happened to be in process of development into a religion. Such a transformation was certainly very foreign to the really classical time of Greece and Rome. The pious belief in the efficacy and power of the gods and in their appearances and manifestations, as well as the traditional worship, could have no bond of union with speculations concerning the essence and ultimate cause of things. The idea of a religious dogma which was at once to furnish a correct theory of the world and a principle of conduct was from this standpoint completely unintelligible. But philosophy, particularly in the Stoa, set out in search of this idea, and, after further developments, sought for one special religion with which it could agree or through which it could at least attain certainty. The meagre cults of the Greeks and Romans were unsuited for this. So men turned their eyes towards the barbarians. Nothing more clearly characterises the position of things in the second century than the agreement between two men so radically different as Tatian and Celsus. Tatian emphatically declares that salvation comes from the barbarians, and to Celsus it is also a "truism" that the barbarians have more capacity than the Greeks for discovering valuable doctrines.[347] Everything was in fact prepared, and nothing was wanting. About the middle of the second century, however, the moral and rationalistic element in the philosophy and spiritual culture of the time was still more powerful than the religious and mystic; for Neoplatonism, which under its outward coverings concealed the aspiration after religion and the living God, was only in its first beginnings. It was not otherwise in Christian circles. The "Gnostics" were in the minority. What the great majority of the Church felt to be intelligible and edifying above everything else was an earnest moralism.[348] New and strange as the undertaking to represent Christianity as a philosophy might seem at first, the Apologists, so far as they were understood, appeared to advance nothing inconsistent with Christian common sense. Besides, they did not question authorities, but rather supported them, and introduced no foreign positive materials. For all these reasons, and also because their writings were not at first addressed to the communities, but only to outsiders, the marvellous attempt to present Christianity to the world as the religion which is the true philosophy, and as the philosophy which is the true religion, remained unopposed in the Church. But in what sense was the Christian religion set forth as a philosophy? An exact answer to this question is of the highest interest as regards the history of Christian dogma. 2. _Christianity as Philosophy and as Revelation_.
