IX. The Prophetical Documents and the Origin of Christianity

For the ancient Persian civilization, the external, physical reality exists as a sphere of activity. It was looked upon as the expression of a hostile Deity, but the hope arose that with the aid of the God of Light this substantial field of reality might be penetrated, that it might be changed into something permeated by spiritual powers and good divinities. Thus the adherents of the Persian civilization already sensed somewhat the reality of the physical world. It is true they still considered it the realm of the God of Darkness, but for all that, they always hoped that they might be able to incorporate within it the forces of the good gods.
