While the logic of divine simplicity may be compelling—God is most absolute in existence and so cannot depend upon that which is not God for any actuality of His being—the doctrine carries with it some deeply counterintuitive and, to some, even strange implications. Chiefly, it means that all that is in God is God. There is no distinction in Him between His act of existence and essence, between His substance and attributes, or between His nature and His intrinsic activity. All these things are nothing but God and do not exist in Him as principles or determinations of His being. From this follow some curious implications for our language about God. It means that our ordinary creaturely patterns of speech (e.g., subject + predicate) do not quite fit God in the way that they fit creatures.
