Paul Tillich

Systematic Theology

"The being of God is being-itself. The being of God cannot be understood as the existence of a being alongside others or above others. If God is a being, he is subject to the categories of finitude, especially to space and substance. Even if he is called the "highest being" in the sense of the "most perfect" and the "most powerful" being, this situation is not changed. They place him on the level of other beings while elevating him above all of them...Many confusions in the doctrine of God and many apologetic weaknesses could be avoided if God were understood first of all as being-itself or as the ground of being."
