The Gospel was hellenised in the second century in so far as the Gnostics in various ways transformed it into a Hellenic religion for the educated. The Apologists used it--we may almost say inadvertently--to overthrow polytheism by maintaining that Christianity was the realisation of an absolutely moral theism. The Christian religion was not the first to experience this twofold destiny on Graeco-Roman soil. A glance at the history of the Jewish religion shows us a parallel development; in fact, both the speculations of the Gnostics and the theories of the Apologists were foreshadowed in the theology of the Jewish Alexandrians, and particularly in that of Philo. Here also the Gospel merely entered upon the heritage of Judaism.[345] Three centuries before the appearance of Christian Apologists, Jews, who had received a Hellenic training, had already set forth the religion of Jehovah to the Greeks in that remarkably summary and spiritualised form which represents it as the absolute and highest philosophy, i.e., the knowledge of God, of virtue, and of recompense in the next world. Here these Jewish philosophers had already transformed all the positive and historic elements of the national religion into parts of a huge system for proving the truth of that theism. The Christian Apologists adopted this method, for they can hardly be said to have invented it anew.[346] We see from the Jewish Sibylline oracles how wide-spread it was. Philo, however, was not only a Stoic rationalist, but a hyper-Platonic religious philosopher. In like manner, the Christian Apologists did not altogether lack this element, though in some isolated cases among them there are hardly any traces of it. This feature is most fully represented among the Gnostics.
