Christianity & Zoroastrianism
Good and Evil: The Cosmic Struggle and the Cross
At the heart of Zoroastrian faith is a great moral drama: from the beginning, two spirits, one choosing truth (asha) and the other the lie (druj), stand opposed, and all creation and every human life are caught up in the struggle between good and evil. Each person must choose a side, and history moves toward the final victory of good. Christianity shares this deep moral seriousness, the conviction that good and evil are really at war and that our choices matter eternally. But it tells the story differently: evil is not a second power coeternal with God, but the corruption of a good creation by rebellion, and it is defeated not by an even contest but by God himself entering the battle and winning through the Cross. A cosmic struggle between two spirits, and a good creation rescued by the Cross, is the difference we hold with respect.
What Zoroastrianism teaches
The Gathas set out the primal choice between two spirits, the good and the evil, in thought, word, and deed:
Every soul, like the spirits, must choose between asha (truth, right order) and druj (the lie); the good spirit is allied with Ahura Mazda, and the hostile spirit (later named Angra Mainyu) with the lie. History is the working-out of this conflict toward the triumph of good.
What Christians believe
Christians take the war of good and evil with equal seriousness, but hold that evil is not a rival god; it is a corruption of what God made good, and it is undone at the Cross.
Where they meet
Both refuse to be naive about evil: it is real, it is at war with good, and no one is a mere bystander. Both call each person to choose truth over the lie, light over darkness, and both believe good will finally triumph, not by chance but toward a purposed end.
Where they differ
Zoroastrianism frames reality as a struggle between two opposed spirits, good and evil confronting each other from the start. Christianity confesses one good God whose creation was wholly good, into which evil came as corruption and rebellion, not as an equal and eternal power. And it holds that evil is defeated not by a balanced war but by God himself, who bears its worst at the Cross and breaks it. A contest of two spirits, or a good creation rescued by the Cross, is the honest difference here.
Zoroastrian sources: the Gathas of Zarathushtra and the wider Avesta; Gathic renderings follow widely published translations (L. H. Mills, Sacred Books of the East vol. 31, public domain, and later scholars such as Mary Boyce), which vary, compare others. Bible: King James Version.

The word itself
Asha and Druj (asha, druj) → truth and the lie → right order versus falsehood
In Zoroastrianism asha is truth, right order, and righteousness, while druj is the lie, disorder, and falsehood; the moral life is the choice of asha over druj, echoing the cosmic struggle of the good and evil spirits. Christianity shares the seriousness of good against evil, but holds evil to be a corruption of a good creation, defeated by God at the Cross (1 John 3:8).
Frequently asked questions
- Is Zoroastrianism dualistic?
- It sees reality shaped by a struggle between two primal spirits, good and evil, truth (asha) and the lie (druj), and calls each person to choose the good. In the Gathas the two spirits are twins in conflict, the better and the bad in thought, word, and deed (Yasna 30.3). Yet Ahura Mazda, the good Wise Lord, is supreme, and good is destined to win.
- How do Christians understand evil differently?
- Christians hold that God's creation was wholly good (Genesis 1:31) and that evil is not a second eternal power but a corruption and rebellion within that good creation, defeated not by an even contest but by God himself at the Cross (1 John 3:8). A struggle of two coeternal spirits, or a good creation rescued by God, is the difference.
Come and see
Zoroastrianism awaits a savior yet to come and calls you to choose truth over the lie; the Gospel tells of the Savior who has already come, and of wise men from the East who came seeking him. The most direct way to know Jesus is to read his words for yourself. There is no pressure here.
