Thought this was an interesting article which I discovered as I was studying a bit on the nature of God in Gregory’s writings.
‘Apophaticism consists in negating that which God is not; one eliminates firstly all creation, even the cosmic glory of the starry heavens and the intelligible light of the angels in the sky. Then one excludes the most lofty attributes, goodness, love, wisdom. One finally excludes being itself. God is none of all this; in His own nature He is the unknowable. He „is not.” But here is the Christian paradox; He is the God to whom I say „Thou,” Who calls me , Who reveals Himself as personal, as living.’
Anyway, read the rest if you want.
