In Gnostic cosmology—particularly within the classic Sethian Gnostic texts like the Apocryphon of John—the Monad, Barbelo, and Christ form the supreme, primordial trinity. This divine triad represents the unfolding of ultimate reality from a single, unknowable source into a cosmic family that acts as the blueprint for spiritual liberation.
Unlike the orthodox Christian Trinity, the Gnostic triad functions as a cascading series of intellectual reflections and emanations within the Pleroma (the divine fullness).
