The answers to these questions appear paradoxical. The theses of the Apologists finally overcame all scruples in ecclesiastical circles and were accepted by the Graeco-Roman world, because they made Christianity _rational_ without taking from, or adding to, its traditional historic material. The secret of the epoch-making success of the apologetic theology is thus explained: These Christian philosophers formulated the content of the Gospel in a manner which appealed to the common sense of all the serious thinkers and intelligent men of the age. Moreover, they contrived to use the positive material of tradition, including the life and worship of Christ, in such a way as to furnish this reasonable religion with a confirmation and proof that had hitherto been eagerly sought, but sought in vain. In the theology of the Apologists, Christianity, as the religious enlightenment directly emanating from God himself, is most sharply contrasted with all polytheism, natural religion, and ceremonial. They proclaimed it in the most emphatic manner as the religion of the spirit, of freedom, and of absolute morality. Almost the whole positive material of Christianity is embodied in the story which relates its entrance into the world, its spread, and the proof of its truth. The religion itself, on the other hand, appears as the truth that is surely attested and accords with reason--a truth the content of which is not primarily dependent on historical facts and finally overthrows all polytheism.
