I have met a couple of California Zoros. One of their beliefs is that the Magi mentioned in the Gospel account were Zoroastrians.
"the Magi mentioned in the Gospel account were Zoroastrians."
The Magi = Zoroastrian Priests, originally Medes in ancient Iran, adopted Zoroastrianism when the faith spread throughout Iran (Persia). They were also known as early Astrologers/Astronomers. Apparently, they predicted the birth of Christ before it happened.
They were the 3 wise men who travelled to Bethleham for the birth of Jesus Christ.
Typo correction:
Bethleham = Bethlehem
