Is this simlar to Gregory of Nyssa?:
“Aion designates temporality, that which occurs within time.” (G. Florovsky, The Eastern Fathers of the Fourth Century [vol. 7 in Collected Works, Belmont, MA: Nordland Pub. Co., c1972–1987], pp. 209–210.)
Hmm. Not sure, as Philo seems to see various different meanings of aionios 
(aionios is the most controversial, as even BDAG sees aion being sometimes “age”)
It seems that he sees a difference between philosophical aion and biblical aion…
