Twelver Shia IslamIslam

Shares Sunni tawhid and adds a line of divinely appointed Imams, a living scholarly authority one formally follows, and a devotional life built around lament and intercession. Authority sits markedly more centrally than in Sunni practice.

ZoroastrianismAbrahamic-adjacent

A wholly good creator, a real opposing principle, and a cosmos that will be made whole at the end — with human beings as free participants who decide the outcome by what they think, say and do. Matter is good, asceticism is rejected, and the elements are kept ritually pure.
