Born at a time when the peoples of the Iranian plateau were evolving a settled agriculture, Zoroaster broke with the traditional Aryan religions of the region which closely mirrored those of India, and espoused the idea of a one good God – Ahura Mazda. What became known eventually in the west as Zoroastrianism was also the first to link religious belief with profound attachment to personal morality. In Zoroastrian eschatology there is much which has become familiar from reading the Jewish and Christian testaments: heaven, hell, redemption, the promise of a Sashoyant (Messiah), the existence of an evil spirit Ahriman and – most striking of all – the prospect of a final battle for the salvation of man at “the end of time” between Ahura Mazda and Ahriman leading to the latter’s final defeat.
The main contact between westerners and Zoroastrians came in India where they were known as Parsees (Persians), descendants of those who took part in a large scale migration from Persia after the Muslim conquest of that country. Zoroastrians were held (quite wrongly) to worship fire because they kept a permanent flame in their temples. Some even questioned whether they were monotheists at all because Ahriman was referred to as an evil “god”. But all the Abrahamic religions have also struggled to explain “evil” in the world which is why they gave Satan an important role.
Those who might doubt how Persian imperial policy so decisively shaped what we know as Judaism should reflect on the remarkable and first ever declaration of belief in one, universal God by the biblical writer known as “Second Isaiah” during this period. Indeed Isaiah describes King Cyrus as a “Messiah” and the chosen instrument of Yahweh. Interestingly there is evidence that the Persian imperial policy towards the religion of their subject peoples – to allow the traditional name of their gods to be retained but to revise the religions themselves in the image of Zoroastrianism – was also applied in Babylon and Egypt as well as Palestine.
Some claim that a belief in monotheism in Judea developed a little before the Babylonian conquest and exile. But although there is evidence for a centralisation of the different Canaanite-style cults into the worship of Yahweh in the capital – Jerusalem – over this period the most which can be said was that a form of monolatry, a belief in one God for a particular people had emerged.
The Persian influence on Judaism was powerful and long lasting. Certainly the profound belief in the end of days exhibited by the Dead Sea Scroll communities in the immediately pre-Christian era and indeed the images employed by the Christian evangelist, John, in his Apocalypse, display a clear continuity of influence.
What – at the very least – were the deep affinities between Zoroastrianism and Judaism goes a long way to explain what over the centuries were the close and friendly relations between Persians and Jews. The influence of 20th century religious-political ideologies have poisoned that relationship. Perhaps a greater acknowledgement by Jews, Christians and Muslims of their Persian Zoroastrian inheritance would be a step to improving those relationships.
