Written by Before the Hebrew prophet named Cyrus, Zarathustra had already asked who was the first Father of Aša.
Not merely the father of honest speech.
The source of cosmic Truth-Order.
The rightly ordered reality against which the Lie stands condemned.
And the name at the center of that older Iranian religious framework was Ahura Mazda.
Then came the Persian Empire.
Babylon fell in 539 BCE.
The Babylonian royal account credited Marduk with choosing Cyrus.
The Hebrew prophet credited Yahweh with choosing Cyrus.
Yet the Hebrew text itself acknowledged something extraordinary:
Cyrus did not know the God who was claiming him.
Then Darius came to power.
Within approximately nineteen years of Babylon’s conquest, the cliffs of Behistun were being inscribed with a royal account invoking Ahura Mazda and denouncing the Lie.
Not in a modern reconstruction.
Not in a theological commentary.
In the imperial record itself.
The historical sequence now stands before us.
The older Gathic question: Who is the Father of Aša?
The Hebrew declaration: I alone created light and darkness.
The Persian inscription: Ahura Mazda granted the kingdom, and the Lie deceived the people.
The resemblance between the Gathic creation questions and Second Isaiah has been recognized by established scholars.
Yet Isaiah does something different.
He places the entire declaration under Yahweh’s exclusive name.
The God whose scriptural name is Jealous now claims sole cosmic sovereignty.
And that claim enters the surviving record during the very historical transformation brought about by Persian power.
Is the original source of cosmic Truth-Order identified by a jealous demand for exclusive recognition?
Or by the divine relationship to Aša itself?
That is the question the Mazda/Father investigation brings to the evidence.
The text of Isaiah demands that no other deity receive the glory.
The historical investigator is under no obligation to accept that demand as proof.
A divine claim does not authenticate itself.
A royal inscription does not authenticate itself.
Truth must be tested against Truth.
And when we finally reach John 8, where Jesus distinguishes his testimony of truth from the father of the lie, the question of divine identity becomes more than a contest of inherited names.
The older Father-of-Aša tradition is now part of the comparison.
So examine the chronology.
Examine the claims.
Examine the character.
Then ask which divine identity best fits the ultimate source of cosmic Truth-Order.
Jealous demands recognition.
Ahura Mazda is named in the older inquiry into the source of Aša.
One is a declaration of exclusivity.
The other is a profound theological account of cosmic reality.
And when an exclusive claim meets a competing historical record, its name cannot exempt it from examination.
Aša knows Aša.
And Truth does not need jealousy to establish its authority.
