The Mystical Theology

The Mystical Theology is the brief, seminal treatise of the anonymous author known as Pseudo-Dionysius, a Christian writer of around 500 working under the borrowed name of Saint Paul's Athenian convert. Its central claim is that the divine is approached not by affirmation but by negation, stripping away every concept and image until the mind passes beyond knowing itself into union with the ineffable.

The method is apophatic, or "negative," theology. On the model of Moses ascending into the cloud on Sinai, the soul rises through the quieting of intellect and sense into a "divine darkness" or "luminous darkness" that is not ignorance but a super-knowing union prior to all images, beyond both affirmation and denial.

Synthesising Neoplatonic philosophy, especially that of Proclus, with Christian theology, the work supplied a vocabulary of unknowing that became a cornerstone of Christian and later nondual mysticism. Its map of reality as a graded outflow from and return to the One, together with its account of contemplative silence, shaped a millennium of mystical thought.
