The one, or naked and empty unity, even in the Unitarian mind is not the equivalent of God. When he says one, he still asks, one what? The answer is, one God, which implies even with him something more than unity. It implies unity and its real and necessary contents as living or actual being. Unity is an abstract conception formed by the mind operating on the intuition of the concrete, and as abstract, has no existence out of the mind conceiving. Like all abstractions, it is in itself dead, unreal, null. God is not an abstraction, not a mere generalization, a creature, or a theorem of the human mind, but one living and true God, existing from and in himself, _ad se et se_. He is real being, being in its plenitude, eternal, independent, self-living, and complete in himself. To live is to act. To be eternally and infinitely living is to be eternally and infinitely acting, is to be all act; and hence philosophers and theologians term God, in scholastic language, most pure act, _actus purissimus_. But act, all act demands, as its essential conditions, principle, medium, and end. Unity, then, to be actual being, to be eternally and purely act in itself, must have in itself the three relations of principle, medium, and end, precisely the three relations termed in Christian theology Father, Son, and Holy Ghost--the Father as principle, the Son as medium, and the Holy Ghost as end or consummation of the divine life. These three interior relations are essential to the conception of unity as one living and true God. Hence the radical conception of God as triune is essential to the conception of God as one God, or real, self-living, self-sufficing unity. There is nothing in this view of the Trinity that asserts that one is three, or that three are one; nor is there anything that breaks the divine unity, for the triplicity asserted is not three Gods, or three divine beings, but a threefold interior relation in the interior essence of the one God, by virtue of which he is one actual, living God. The relations are in the essence of the one God, and are so to speak the living contents of his unity, without which he would be an empty, unreal abstraction; one--nothing.
