St. Cyril of Jerusalem (313-386) wrote:
“For we do not explain what God is but candidly confess that we do not have exact knowledge concerning Him. For when speaking of the things concerning God, to confess our ignorance is the best knowledge.”
“But some one will say, if the Divine substance is incomprehensible, why do you speak of these things? Just because I cannot drink all the water in a river, am I not, in moderation, to take the amount that I need? Just because my eyes cannot take in all of the Sun, can I not see the little that I need? Or again, just because I have entered into a great garden, and cannot eat everything in it, would you have me go away altogether hungry?”
At least we can understand and enjoy some Divine Substance.
“If you had known me, you would have known my Father also. From now on you do know him and have seen him.” Jesus
