What are the similarities between Zoroastrianism and Christianity, and how do the two

Just curious as to your take on the comparison of these two religions.

Peace and Knowledge!

well Zoroastrianism was the first monotheistic religion and it influenced Christianity on the idea of hell . but those guys went crazy and came up with this dogma stuff that scared the living hell (not intentional joke) out of people.

Similar, from what I understand. Christianity more "well-developed." In my heart I feel that Z is Christianity that got corrupted over time from lack of fellowship.

The Bah??? Faith teaches that both Zartosht (Zoroaster) and ??s? (Jesus) were Manifestations of God: a Manifestation of God (Mizar-i-il?h?) is like a mirror who reflects the Sun but is not himself the Sun; he is united to a physical body endowed with a rational soul, but his divine nature renders him distinct.

The similarities between Zoroastrianism and Christianity are too numerous to enumerate here, but a great book to reference would be "Zoroastrianism: An Introduction to an Ancient Faith" by Peter Clark.

"Zarathustra was thus the first to teach the Doctrines of an individual Judgment, Heaven and Hell, the future Resurrection of the Body, the general Last Judgement, and Life everlasting for the reunited Soul and Body.These Doctrines were to become familiar Articles of Faith to much of Mankind, through borrowings by Judaism, Christianity and Islam; yet it is in Zoroastrianism itself that they have their fullest logical Coherence..."
-Mary Boyce, Op. Cit. p. 29

How do they relate? Well, Zoroastrianism had a huge impact on the developments of Christianity.
In fact, Jesus was very much so a Savior (Saoshyant), in the Zoroastrian sense.

What are Saoshyants? Saoshyant is a Gathic Avestan Term for someone who will bring progress to mankind.

Yes the similarity is that both are based on a foundation of Love & Righteous actions. Their differences however are huge.
The Zarathushti faith advises a pathway to heaven (utopia) based on acts of selflessness throughout ones' life. One cannot take credit for another persons' sacrifices.
Christianity insists that one goes to heaven ONLY if one believes in Jesus Christ.
Also while Jesus is also God; In the Zarathushti scheme of things, a mortal can merge into divinity but not become the exclusive divinity, much like a drop of water cannot fill a bucket by itself.
