GOD - The Unity of God
The Father of all is far removed from the emotions and passions which are common to men. He is simple, uncompounded, without diversity of parts; wholly identical and consistent; since he is all understanding, all spirit, all thought, all hearing, all seeing, all light, and the whole source of all that is good.
It is best for us to begin with the first and greatest principle, that is with God the Creator … and to show that there is nothing above him or beyond him. It was of his own decision and free act that he made all things, not moved by anything; since he is the only God, the only Lord, the Only Creator, the only Father, the only Sovereign, and it is he who bestows existence on all things.
How could there be any other Totality beyond him: or another Principle or Power or another God? For God who is the totality of all these must needs include all things in his infinite being, while he himself cannot be included by any other thing. If there is anything outside him he is then not the totality of all things, nor does he contain all things.
~ St. Irenaeus of Lyons
