The ancient Greeks saw in Zoroastrianism the archetype of the dualistic view of the world and of human destiny. Zarathustra was supposed to have instructed Pythagoras in Babylon and to have inspired the Chaldean doctrines of astrology and magic. It is likely that Zoroastrianism influenced the development of Judaism and the birth of Christianity. The Christians, following a Jewish tradition, identified Zoroaster with Ezekiel, Nimrod, Seth, Balaam, and Baruch and even, through the latter, with Jesus Christ himself. On the other hand, as the presumed founder of astrology and magic, Zarathustra could be considered the arch-heretic. Though Zoroastrianism was never, even in the thinking of its founder, as insistently monotheistic as, for instance, Judaism or Islam, it does represent an original attempt at unifying under the worship of one supreme god a polytheistic religion comparable to those of the ancient Greeks, Latins, Indians, and other early peoples. Its other salient feature, namely dualism, was never understood in an absolute, rigorous fashion. Good and evil fight an unequal battle in which the former is assured of triumph. God’s omnipotence is thus only temporarily limited. In this struggle all human beings must enlist because of their capacity for free choice. They do so with soul and body, not against the body, for the opposition between good and evil is not the same as the one between spirit and matter. Contrary to the Christian or Manichaean (from Manichaeism—a Hellenistic, dualistic religion founded by the Iranian prophet Mani) attitude, fasting and celibacy are proscribed except as part of the purificatory ritual. The human struggle has a negative aspect, nonetheless, in that it must strive for purity and avoid defilement by the forces of death, contact with dead matter, etc. Thus, Zoroastrian ethics, though in itself lofty and rational, has a ritual aspect that is all-pervading. On the whole, Zoroastrianism is optimistic and has remained so even through the hardship and oppression of its believers (Source: Encyclopedia Britanica).
