Zoroaster, Salem missionary descendant = Zarathustra, founder of Zoroastrianism

Somewhere in northeastern Iran, probably between 1500 and 1200 BCE though some scholars argue for as late as 600 BCE, a young priest of the old Iranian religion had a series of visions in which a god named Ahura Mazda, the Wise Lord, appeared to him and commissioned him as a prophet. The young priest's name was Zarathushtra in his native Avestan, Zoroaster in the later Greek transcription. He composed a body of hymns, the Gathas, in archaic Avestan meter, that survive as the only firmly attested compositions of the founder of Zoroastrianism. The Gathas are dense, theologically sophisticated, and often obscure to modern translators, but they make several things clear. There is one supreme God, Ahura Mazda, who is the creator and the source of righteousness. There are spirits of good and spirits of evil whose choice is contested in the human heart. There is a coming day of judgment when the cosmic balance will be set right. The teaching is recognizably monotheistic, ethically dualistic, and eschatologically oriented.

The Urantia Book at 95:6.1 records that from Palestine some of the Melchizedek missionaries passed on through Mesopotamia and to the great Iranian plateau, where for more than five hundred years the Salem teachers made headway, and the whole nation was swinging to the Melchizedek religion when a change of rulers precipitated a bitter persecution which practically ended the monotheistic teachings of the Salem cult. The doctrine of the Abrahamic covenant was virtually extinct in Persia when, in that great century of moral renaissance, the sixth before Christ, Zoroaster appeared to revive the smouldering embers of the Salem gospel. Paper 95:6.2 adds the specific historical detail: Zoroaster was a virile and adventurous youth who, on his first pilgrimage to Ur in Mesopotamia, learned of the traditions of the Caligastia and Lucifer rebellion along with many other traditions, all of which made a strong appeal to his religious nature. As the result of a dream while in Ur, he settled upon a program of returning to his northern home to undertake the remodeling of the religion of his people.

This is one of the most specific historical claims the UB makes about a major world religion. Zoroaster's monotheistic reform was not an independent innovation. It was the deliberate revival, by a man who had directly encountered Salem-derived material at Ur in Mesopotamia, of a Salem teaching that had been present in Iran for five centuries before being suppressed. The UB further records that he had imbibed the Hebraic idea of a God of justice, the Mosaic concept of divinity, and that the idea of a supreme God was clear in his mind. He set down all other gods as devils and consigned them to the ranks of the demons of which he had heard in Mesopotamia. He had learned of the story of the Seven Master Spirits as the tradition lingered in Ur and accordingly created a galaxy of seven supreme gods with Ahura-Mazda at its head.

Mary Boyce's three-volume A History of Zoroastrianism (1975-1991) is the foundational modern academic treatment. Boyce documents Zoroaster's radical monotheistic reform of Iranian polytheism, dating his activity to approximately 1500-1200 BCE on linguistic grounds (the Gathas are in archaic Avestan close to the Vedic Sanskrit of the Rig Veda). She presents the Gathas as a coherent ethical-monotheistic teaching that is unprecedented in its Iranian context. Peter Clark's 1998 Zoroastrianism notes that Zoroastrianism's ethical monotheism was without parallel in the surrounding ancient Near Eastern context, with its sophisticated articulation of the moral struggle, the active human role in choosing good, and the eschatological framework of final judgment.

The structural fit with the UB account is precise. A reformer who had encountered Salem-derived monotheism at Ur, the Salem missionary outpost the UB names as the historical Ur of the Chaldees that Abraham came from, would produce exactly what the historical Zarathushtra produced: a monotheistic reform of Iranian polytheism, with a single supreme God at the center, ethical dualism in the choice between good and evil, eschatological judgment as the final sorting of the cosmic struggle, and seven supreme spiritual beings as the structural memory of the Seven Master Spirits. Each of these elements aligns precisely with a Salem-derived theological inheritance, transmitted through the actual mechanism the UB names: a personal pilgrimage to Ur, encounter with the lingering tradition, a vocational dream of religious reform, and return to Iran to enact the reform.

The strongest counterargument is that Zoroastrianism is universally treated by academic scholarship as an independent Iranian innovation, with no need for external Salem influence to explain it. The reply is that the academic explanation, that the reform emerged from within the Iranian religious tradition, does not actually explain why the monotheistic reform appeared in Iran specifically rather than elsewhere, and why it appeared with this particular cluster of features (monotheism, ethical dualism, eschatological judgment, sevenfold supreme beings). The UB account explains the cluster by tracing it to a specific historical encounter with Salem-derived material, and the explanation has the merit of accounting for both the Iranian particularity and the cluster of distinctive features.

What the parallel implies is significant for the comparative history of religion. Zoroastrianism is the missing link between Salem-derived monotheism and the major Western monotheisms. Through its influence on post-exilic Judaism (heaven, hell, devils, angels, eschatology), Zoroastrianism transmitted the Salem theological cluster into the Hebrew Bible and from there into Christianity and Islam. The UB account makes this transmission lineage intelligible by identifying its actual historical origin: a Salem-derived teaching, suppressed in Iran but revived by Zarathushtra after his Ur pilgrimage, then transmitted through the Achaemenid empire's contact with the exiled Jews into the post-exilic Jewish theological synthesis.
