For as we say that there is one God, confessing the Father, and not denying the Son under the true Name of the Godhead; so, too, we exclude not the Holy Spirit from the Unity of the Godhead, and do not assert but deny that there are three Gods, because it is not unity but a division of power which makes plurality. For how can the Unity of the Godhead admit of plurality, seeing that plurality is of numbers, but the Divine Nature does not admit numbers?
