Godhood = Dominion

As for all of the errors which the modern Christians have fallen into concerning the doctrine of the Trinity, they seem to be owing to one source in particular: their restricting the definition of God to mean the one self-existent Jehovah. In the Old and New Testaments, however, when polytheism was the reigning notion among mankind, the word God was much more “comprehensive.”1 Ancient Judaism was a popular religion, adapted to the common notions of the world at that time, and delivered in the common language, to men of no education; a mass of ignorant slaves, bred up to labour in the brick kiln. Nothing was known to these men of a Trinity in Unity, nor of a Hypostatic Union, nor any other scholastic term which men have since invented. But they understood the word God in the same plain sense in which it was understood by all the neighboring nations, and in the same plain and unscholastic sense in which it was understood by the most ancient fathers. It was understood by them to express relative dominion, as it is explained by Sir Isaac Newton:

This Being governs all things, not as the soul of the world, but as Lord over all: And on account of his dominion he is wont to be called Lord God παντοκρáτωρ or Universal Ruler. For God is a relative word, and has a respect to servants; and Deity is the dominion of God, not over his own body, as those imagine who fancy God to be the soul of the world, but over servants. The supreme God is a Being eternal, infinite, absolutely perfect; but a being, however perfect, without dominion, cannot be said to be Lord God; for we say, my God, your God, the God of Israel, the God of Gods, and Lord of Lords; but we do not say, my Eternal, your Eternal, the Eternal of Israel, the Eternal of Gods; we do not say, my Infinite, or my Perfect: These are titles which have no respect to servants. The word God usually signifies Lord; but every lord is not a God. It is the dominion of a spiritual being which constitutes a God; a true, supreme or imaginary dominion makes a true, supreme or imaginary God.” (Newton, General Scholium)
