Theological Dissertation on the Theologoumena of Macarius Magnes

That is, "God, however, alone having rule and Monarchy, not being begotten, presides over those who are generated; being uncreated and lacking a beginning, he holds the creatures in his power, and, providing, he rules not the similar, but the dissimilar." Wherefore, also, with respect to the Polytheism of the Gentiles, he calls the same "the only true ruler God," which phrase and idea of the Supreme Divinity he repeated from D. Paul himself, 1 Tim. VI, 15-16, where God is called "the blessed and only Potentate," with which words the Holy Apostle supplies an argument for true Deity, omnipotence, and divine Monarchy. And this is the very thing that our Macarius, along with other Fathers of the primitive Church, calls the Monarchy of God, namely the unity and headship of the true and essential God, in opposition to polytheism multitude of gods or the multitude of false gods among the Gentiles.

1) Concerning which PETRONIUS says in the Satyricon, p. 62: "Our region is so full of present Divinities that you could more easily find a God than a man."
2) Compare IO. GEORG. DORSCHEUS, Pentad of Theological Dissertations, in his preliminary dissertation or Consideration of the titles by which God is distinguished in 1 Tim. VI, 15-16; and also IO. ESBERG'S dissertation on Divine Monarchy, held at Uppsala, 1708.
3) Conveniently, indeed, ANT. AUGUST. TOUTTÉE, a Benedictine, observes in his Preface to the Sixth Catechesis of Cyril of Jerusalem, p. 85: "By the name of the Monarchy of God, our ancient writers understand the one headship of the unique God over all things, of which he is the one origin and author. For the word arche beginning/principle/rule, embracing a double understanding, sounds both as headship and as origin. Both, however, fit God for one and the same reason, since the rationale of headship and domination belongs to him from the creation and the origin placed into things."
