In which case my Chicago friend would have asked, "If you destroy a belief in Ormuzd, and that he gave the only supernatural moral law to Zoroaster, how will children ever be taught what is right and what is wrong, and how can they ever know that it is not right to lie and kill and steal?"
"Their creed is of the simplest kind; it is to fear God, to live a life of pure thoughts, pure words, pure deeds, and to die in the hope of a world to come. _It is the creed of those who have lived nearest to God and served him faithfullest in every age_, and wherever they dwell who accept it and practice it, they bear witness to that which makes them children of God and brethren of the prophets, among whom Zoroaster was not the least. The Jews were carried away as captives to Babylon some 600 years before Christ, and during the seventy years of their exile there, they came into contact with the Persian religion _and derived from it ideas about the immortality of the soul, which their own religion did not contain. They also borrowed from it their belief in a multitude of angels, and in Satan as the ruler over evil spirits_." [So you see that even our devil is a borrowed one, and it now seems to be about time to return him with thanks. ] "The ease with which man believes in unearthly powers working for his hurt prepares a people to admit into its creed the doctrine of evil spirits, and although it is certain that the Jews had no belief in such spirits before their captivity in Babylon, they spoke of Satan (which means _an adversary_) as a messenger sent from God to watch the deeds of men and accuse them to Him for their wrong-doing. Satan thus becoming by degrees an object of dread, upon whom all the evil which befell man was charged, the minds of the Jews were ripe for accepting the Persian doctrine of Ahriman with his legions of devils. Ahriman became the Jewish Satan, _a belief in whom formed part of early Christian doctrine, and is now but slowly dying out. What fearful ills it has caused, history has many a page to tell_. The doctrine that Satan, once an angel of light, had been cast from heaven for rebellion against God, and had ever since played havoc among mankind, gave rise to the belief that he and his demons could possess the souls of men and animals at pleasure. Hence grew the belief in wizards and witches, under which millions of creatures, both young and old, were cruelly tortured and put to death. We turn over the smeared pages of this history in haste, thankful that from such a nightmare the world has wakened."
