Anyway, it is the idea of creation that the Zoroastrians believe in that caught me. Ahura (the Wise Lord) created the entire world. He believed in the power of truth. (The Zoroastrians equate truth with goodness) However, he also created Ahriman (the Devil) and Ahriman chose the lie. Ahriman exists so that we may have choice, or free will.
Zoroastrianism was also among the first religions to have a concept of an eternal reward or punishment. (However, once in hell, redemption was possible). In the end, it was said by Zoroaster, that Ahura would conquer the lie and humanity would live in supreme happiness for the rest of eternity. (This was supposed to happen around 2600 ad)
It gets even more interesting. Here is a direct quote from one of my sources.
This dualistic idea sounded very familiar to me, and only today did I realize that the relationship between Ahura and Ahriman sounds very much like the relationship between the Creator and Lord Foul.This dualist view eventually became the orthodox position. Its development may have owed much to the Magi, a hereditary priestly caste, although their role is unclear. From them, however, the Greco Roman world learned much of what it knew of the religion. An important reform movement, however, arose within Zoroastrianism - the movement around Zurvan. The Zurvanites posited a supreme god, Zurvan (Infinite Time), who had sacrificed for 1,000 years in order to gain offspring. At the end of that time he experienced momentary doubt, and from that doubt arose Ahriman; at the same time, Ormazd came into being because of the efficacy of the sacrifices. At the end of 3,000 years Ahriman crossed the void that separated them and attacked Ormazd. The two made a pact to limit the struggle, and Ahriman fell back into the abyss, where he lay for 3,000 years.
During that period Ormazd created the material and spiritual world; in retaliation, Ahriman called into being six demons and an opposing material world. In the next 3,000 year period Ahriman attempted to corrupt the creation of Ormazd; he was successful but was trapped in the world of light. The final period of 3,000 years was ushered in by the birth of Zoroaster, who revealed this struggle to man; the prophet is to be followed by three saviors, appearing at intervals of 1,000 years. At the appearance of the last, a day of judgment will occur, the drink of immortality will be offered to those who have fought against Ahriman, and a new creation will be established.
I further discovered that the vast majority of modern Zoroastrians live in India, where Donaldson grew up. Do you suppose that the theology of the land is in any way influenced by this Theology?
