Elucidating the nature of the relationship between epistemological "is-statements" and ethical "ought-statements" gains added complexity with the introduction of revelation. Despite scholarly emphasis on the unilateral influence of knowledge on ethics, a notable gap persists in understanding how, within Ayatollah Javadi Amoli’s intellectual framework, epistemology and revealed ethics establish a reciprocal and elevating relationship, and what mechanism underpins this interaction within the paradigm of "religious rationality." Accordingly, the primary objective is to formulate a model of this reciprocal interaction. Employing qualitative content analysis and logical reasoning, key works of Ayatollah Javadi Amoli were scrutinized to explicate the systematic interplay among core concepts such as "reason and revelation," "purification of the soul," and "intuitive knowledge" within his theory of religious rationality. Findings reveal this relationship as a "reciprocal, organic, and ascending cycle": 1. Initial knowledge (from reason, innate disposition, revelation) → action; 2. Action + piety → soul purification (barrier removal, necessary condition) + divine bestowal of discernment (intuitive insight, sufficient condition); 3. Elevated knowledge → superior action. Commitment to virtues and soul purification, as an epistemological prerequisite, eliminates perceptual obstacles (vices) and enhances the knowing agent's capacity for higher epistemic levels, such as "discernment" (furqān) and "intuitive knowledge." This elevated knowledge, in turn, yields superior ethical conduct. This dynamic cycle is embedded in the paradigm of religious rationality, wherein reason operates in alignment with revelation, while revelation serves as its expositor, complement, and overseer.
