Theology is commonly understood as the systematic study of the divine and the exploration of religious truths. Hermeneutics in its more narrow sense refers to theories of textual interpretation, i.e., theories of how we read, understand, and interpret texts. This chapter presents a topical survey of “Classical” Zoroastrian theological discourse and hermeneutics as found in just such a body of literature, the Pahlavi texts from about the 3rd to the 12th century CE. In terms of Zoroastrian textuality, the Pahlavi corpus represents the crucial intellectual pivot between an ancient oral society reflected in the extant Avestan texts and the fully literate Islamic era in the Iranian world from the mid‐7th century onwards. It bears stating that while the Pahlavi corpus is not the earliest or largest body of Zoroastrian literature, it is nonetheless the first one where we find religious discourse gaining a reflective dimension.
