21. (3) The Divine Esse is at once Esse [Being] in itself and Existere [Manifestation] in itself. Jehovah God is Esse in itself, because He is the I Am, the Only, and the First, from eternity to eternity, the source of everything that is, without whom it could not be. In this way and not otherwise He is the Beginning and the End, the First and the Last, the Alpha and Omega. It cannot be said that His Esse is from Itself, because the expression from itself implies something prior, and therefore time; and time is not applicable to the Infinite, which is called infinite from eternity; it also implies another God who is God in Himself, thus it implies God from God, or that God formed Himself; in which case He would neither be uncreate nor infinite, for He would thus have made Himself finite, either from Himself or from another. From the fact that God is Esse in itself it follows that He is Love in itself, Wisdom in itself, and Life in itself, and that He is the Itself, the source of all things, to which each thing must have relation in order to be anything. That God is God because He is Life in itself is evident from the Lord's words in John (5:26) and in Isaiah:
I am Jehovah that maketh all things; that spreadeth forth the heavens alone that stretcheth forth the earth by Myself (44:21) and that He alone is God, and beside Him there is no God (Isa. 45:14, 15, 21, 22; Hos. 13:4). God is not only Esse [Being] in itself, but also Existere [Manifestation] in itself, because Esse without Existere is nothing, equally so Existere unless it is from Esse; therefore where the one is the other must needs be. The same is true of substance and form. Unless a substance is also a form nothing can be predicated of it, and for the reason that having no quality it is in itself nothing. The terms esse and existere are here used, and not essence and existence, because a distinction must be made between esse and essence, and between existere and existence, like that between the prior and the posterior, the prior being more universal than the posterior. To the Divine Esse infinity and eternity are applicable; while to the Divine Essence and Existence, Divine love and wisdom are applicable, and through these two omnipotence and omnipresence, which will be considered in their order.
