The sacred Scriptures teach us to think, in like manner, of the Lord of lords. For they say in one place, “Give thanks to the God of gods, for His mercy endures for ever. Give thanks to the Lord of lords, for His mercy endures for ever;” and in another, “God is King of kings, and Lord of lords.” For Scripture distinguishes between those gods which are such only in name and those which are truly gods, whether they are called by that name or not; and the same is true in regard to the use of the word “lords.”
To this effect Paul says, “For though there be that are called gods, whether in heaven or in earth, as there are gods many, and lords many.” But as the God of gods calls whom He pleases through Jesus to his inheritance, “from the east and from the west,” and the Christ of God thus shows His superiority to all rulers by entering into their several provinces, and summoning men out of them to be subject to Himself, Paul therefore, with this in view, goes on to say, “But to us there is but one God, the Father, of whom are all things, and one Lord Jesus Christ, by whom are all things, and we by Him;” adding, as if with a deep sense of the marvellous and mysterious nature of the doctrine, “Howbeit there is not in every man that knowledge.”
When he says, “To us there is but one God, the Father, of whom are all things; and one Lord Jesus Christ, by whom are all things,” by “us” he means himself and all those who have risen up to the supreme God of gods and to the supreme Lord of lords. Now he has risen to the supreme God who gives Him an entire and undivided worship through His Son— the word and wisdom of God made manifest in Jesus. For it is the Son alone who leads to God those who are striving, by the purity of their thoughts, words, and deeds, to come near to God the Creator of the universe.
I think, therefore, that the prince of this world, who “transforms himself into an angel of light,” was referring to this and such like statements in the words, “Him follows a host of gods and demons, arranged in eleven bands.” Speaking of himself and the philosophers, he says, “We are of the party of Jupiter; others belong to other demons.”
