Much of Christian theology seems to parallel Zoroastrian theology, and in some ways Jesus parallels the Saoshyant of that faith. The Zoroastrian faith holds that the Saoshyant will return to fight evil and initiate the Last Judgement. Arguably, the Zoroastrian thinking could be behind the thought that Jesus will return.

• Belief in both heaven and hell
• Belief in angels
• Belief in seven archangels, which parallel the Zoroastrian yazatas.
• Satan, who fills a unique role in the Abrahamic religions and in Zoroastrianism, where he is called Angra Mainyu or Ahriman
• Belief in the second coming of Jesus (Christianity) and the Saoshyant (Zoroastrianism), in both cases to defeat evil and herald the last days
• Belief in resurrection
• Individual judgement of souls, which in the Zoroastrian case is almost the same as the Islamic belief
• The Last Judgement

The virgin birth of Jesus might have been based on Zoroastrianism, but as it was a common motif in ancient times, it is equally possible to have had a different origin. Matthew's Gospel has the magi ('wise men') come from the east to worship Jesus. This was no doubt to show that even the priests of the great religion would want to worship Jesus, as well as linking the long-awaited birth of the Jewish Messiah to the long-awaited birth of the Zoroastrian Saoshyant, and the virgin birth of Jesus to the virgin birth of the Saoshyant.
