From St Dionysios' Mystical Theology

We therefore maintain that the universal and transcendent Cause of all things is neither without being nor without life, nor without reason or intelligence; nor is it a body, nor has it form or shape, quality, quantity or weight; nor has it any localized, visible or tangible existence; it is not sensible or perceptible; nor is it subject to any disorder or inordination nor influenced by any earthly passion; neither is it rendered impotent through the effects of material causes and events; it needs no light; it suffers no change, corruption, division, privation or flux; none of these things can either be identified with or attributed unto it.
