Aseitas, a Truly Awesome Word!

Aseitas

When God says that He is being and if what He says is to have any intelligible meaning to our minds, it can only mean this: that He is the pure act of existing.

…

Beyond all sensible images, and all conceptual determinations, God affirms Himself as the absolute act of being in its pure actuality. Our concept of God, a mere feeble analogue of a reality which overflows it in every direction, can be made explicit only in the judgement: Being is Being, an absolute positing of that which, lying beyond every object, contains in itself the sufficient reason of objects. And that is why we can rightly say that the very excess of positivity which hides the divine being from our eyes is nevertheless the light which lights up all the rest: ipsa caligo summa est mentis illuminatio.

When St. Jerome says that God is His own origin and the cause of His own substance, he does not mean, as Descartes does, that God in a certain way posits Himself in being by His almighty power as by a cause, but simply that we must not look outside of God for a cause of the existence of God.

"Merton on God"

The one big concept which I got out of its pages was something that was to revolutionize my whole life. It is all contained in one of those dry, outlandish technical compounds that the scholastic philosophers were so prone to use: the word aseitas. In this one word, which can be applied to God alone, and which expresses His most characteristic attribute, I discovered an entirely new concept of God—a concept which showed me at once the belief of Catholics was by no means the vague and rather superstitious hangover from an unscientific age that I had believed it to be. On the contrary, here was a notion of God that was at the same time deep, precise, simple, and accurate and, what is more, charged with implications which I could not even begin to appreciate, but which I could at least dimly estimate, even with my own lack of philosophical training.

Aseitas—the English equivalent is a transliteration: aseity—simply means the power of a being to exist absolutely in virtue of itself, not as caused by itself, but as requiring no cause, no other justification for its existence except that its very nature is to exist. There can be only one such Being: that is God. And to say that God exists a se, of and by and by reason of Himself, is merely to say that God is Being Itself. Ego sum qui sum. And this means that God must enjoy “complete independence not only as regards everything outside but also as regards everything within Himself.

What a relief it was for me, now, to discover not only that no idea of ours, let alone any image, could adequately represent God, but also that we should not allow ourselves to be satisfied with any such knowledge of Him.
