On the Divine Names

Now, since we are speaking of these things, come then, and let us praise the Good, as veritably Being, and giving essence to all things.that be. He, Who is, is superessential, sustaining Cause of the whole potential Being, and Creator of being, existence, subsistence, essence, nature; Source and Measure of ages, and Framer of times, and Age of things that be, Time of things coming into being, Being of things howsoever being, Birth of things howsoever born. From Him, Who is, is age, and essence, and being, and time, and birth, and thing born; the realities in things that be, and things howsoever existing and subsisting. For Almighty God is not relatively a Being, but absolutely and unboundedly, having comprehended and anticipated the whole Being in Himself. Wherefore. He is also called King of the ages, since the whole being both is, and is sustained, in Him and around Him. And He neither was, nor will be, nor became, nor becomes, nor will become — yea rather, neither is. But He is the Being to things that be, and not things that be only, but the very being of things that be, absolutely from before the ages. For He is the Age of ages — the Existing before the ages.
