Against Eunomius
Gregory of Nyssa · c. 335 – c. 395
A vast reply to the claim that unbegottenness names God's essence. Gregory argues that names are human tools invented for human use, that God's essence is infinite and therefore unbounded by any concept, and that the soul's approach to God is a journey with no arrival — always further in, never at the end.
