The passages the Scriptorium holds on screen, word for word from a public-domain translation. Written in Koine Greek.
“For before the brightness, of course neither was there any glory, for concurrently with the existence of the glory there assuredly beams forth its brightness; and it is impossible in the nature of things that one should be severed from the other.”
Gregory of Nyssa, Against Eunomius 2 (trans. Moore & Wilson, NPNF² 5, public domain).
“…no interval intervening between the Father and Him Who is of the Father.”
Gregory of Nyssa, Against Eunomius 2 (trans. Moore & Wilson, NPNF² 5, public domain).
“Good, as long as it is incapable of its opposite, has no bounds to its goodness: its opposite alone can circumscribe it, as we may see by particular examples.”
Gregory of Nyssa, Against Eunomius 1.15 (trans. Moore & Wilson, NPNF² 5, public domain).
Notes
Basil’s younger brother, finishing the argument Basil died in the middle of. Eunomius had answered Basil’s book; Gregory answered Eunomius, at very great length.
Eunomius’ claim was not only that the Son was made. It was that the word “unbegotten” tells you what God actually is — that the divine essence is knowable, and he knew it.
So the brightness argument does double work. You cannot have the glory first and the shining afterwards; there is no moment of glory that is not already shining. No interval, therefore no “there was when he was not.”
And the second move is the one that costs Eunomius everything: no word reaches God’s nature at all. Not “unbegotten,” not any of them. If the nature has no bounds, no term can put a fence round it.
