The beginning of a development which a century later reached its provisional completion in the theology of Origen, that is, in the transformation of the Gospel into a scientific system of ecclesiastical doctrine, appears in the Christian Apologetic, as we already find it before the middle of the second century. As regards its content, this system of doctrine meant the legitimising of Greek philosophy within the sphere of the rule of faith. The theology of Origen bears the same relation to the New Testament as that of Philo does to the Old. What is here presented as Christianity is in fact the idealistic religious philosophy of the age, attested by divine revelation, made accessible to all by the incarnation of the Logos, and purified from any connection with Greek mythology and gross polytheism.[4] A motley multitude of primitive Christian ideas and hopes, derived from both Testaments, and too brittle to be completely recast, as yet enclosed the kernel. But the majority of these were successfully manipulated by theological art, and the traditional rule of faith was transformed into a system of doctrine, in which, to some extent, the old articles found only a nominal place.[5] This hellenising of ecclesiastical Christianity, by which we do not mean the Gospel, was not a gradual process; for the truth rather is that it was already accomplished the moment that the reflective Greek confronted the new religion which he had accepted. The Christianity of men like Justin, Athenagoras, and Minucius is not a whit less Hellenistic than that of Origen. But yet an important distinction obtains here. It is twofold. In the first place, those Apologists did not yet find themselves face to face with a fixed collection of writings having a title to be reverenced as Christian; they have to do with the Old Testament and the "Teachings of Christ" ([Greek: didagmata Christou]). In the second place, they do not yet regard the scientific presentation of Christianity as the main task and as one which this religion itself demands. As they really never enquired what was meant by "Christian," or at least never put the question clearly to themselves, they never claimed that their scientific presentation of Christianity was the first proper expression of it that had been given. Justin and his contemporaries make it perfectly clear that they consider the traditional faith existing in the churches to be complete and pure and in itself requiring no scientific revision. In a word, the gulf which existed between the religious thought of philosophers and the sum of Christian tradition is still altogether unperceived, because that tradition was not yet fixed in rigid forms, because no religious utterance testifying to monotheism, virtue, and reward was as yet threatened by any control, and finally, because the speech of philosophy was only understood by a small minority in the Church, though its interests and aims were not unknown to most. Christian thinkers were
