First, God’s existence (act of being) and essence (quiddity) cannot be constituent components in Him, each supplying what the other lacks. Rather, God must be identical with His existence and essence, and they must be identical with each other. It is His essence to be. Strictly speaking, His act of existence is not what He has, but what He is. 10 Similarly, God does not merely instantiate divinity as a particular concrete instance of it. Rather, He is divinity itself. No man is humanity as such, but God is divinity as such. Many theologians even conclude that God’s essential identity with His own existence is the ontological foundation of His name “I AM” (Ex. 3: 14).
