What if Christ was actually brought up in the Persian faith?

To the teachings of Zarasthustra. Ancient Palestine was an important part of the Persian Empire and Zoroastrianism was the dominant religion in the region for centuries afterwards,possibly up to Christ's time. It would explain a great deal: why Christianity is dualistic,which Judaism is not; why the three Magi - Zoroastrian clergy - would have been the first to be informed by God of His impending manifestation on earth as an infant; why Christ would have told the rabbis that His Father was not their father; why even the writings of the Jewish convert Saul/Paul reflect Zoroastrianism more than Judaism; the striking similarities between Mithraism and Christianity,Mithraism being a European offshoot of Zoroastrianism. Why the teaching of Zoroaster are so similar to Christ's in their emphasis on love,while the Judaic teachings are vengeful and glorify genocide. Serious opinions only,please.
