Pēgē gnōseōs

Pēgē gnōseōs, meaning "The Source of Knowledge," is the most significant written work by St. John of Damascus. This comprehensive synthesis of Christian philosophy and doctrine was highly influential in medieval Latin thought and became a foundational text for Greek Orthodox theology.1

The work is divided into three parts:
* Dialectica: A philosophical introduction drawing from Neoplatonist logic.2
* Historical: Transcribing sections on heresies from an earlier church historian.2
* Ekthesis tes Orthodoxou Pisteos (Exposition of the Orthodox Faith): A theological summary of the teachings of the 4th-century Cappadocian Fathers, presented using Aristotelian terminology.2

This theological segment explored the nature and existence of God, free will, and the human will's inclination toward good. The Exposition served as a model for later theological syntheses and provided key concepts for both Eastern and Western thinkers.2
