3 But it is asked, If men are called gods to whom the word of the Lord came, are the Angels to be called gods, when the greatest reward which is promised to just and holy men is the being equal to Angels? In the Scriptures I know not whether it can, at least easily, be found, that the Angels are openly called gods; but when it had been said of the Lord God, “He is terrible, above all gods,” he adds, as by way of exposition why he says this, “for the gods of the heathen are devils,” that we might understand what had been expressed in the Hebrew, “the gods of the Gentiles are idols,” meaning rather the devils which dwell in the idols. For as regards images, which in Greek are called idols, a name we now use in Latin, they have eyes and see not, and all the other things which are said of them, because they are utterly without sense; wherefore they cannot be frightened, for nothing which has no sense can be frightened.
How then can it be said of the Lord, “He is terrible above all gods, because the gods of the Gentiles are idols,” if the devils which may be terrified are not understood to be in these images. Whence also the Apostle says, “We know that an idol is nothing.” This refers to its earthy senseless material. But that no one may think, that there is no living and sentient nature, which delights in the Gentile sacrifices, he adds, “But what the Gentiles sacrifice, they sacrifice to devils, and not to God: I would not have you partaken with devils.” If therefore we never find in the divine words that the holy Angels are called gods, I think the best reason is, that men may not be induced by the name to pay that ministry and service of religion (which in Greek is called λειτουργία or λατρία) to the holy Angels, which neither would they have paid by man at all, save to that God, who is the God of themselves and men. Hence they are much more correctly called Angels, which in Latin is Nuntii, that by the name of their function, not their substance, we may plainly understand that they would have us worship the God, whom they announce. The whole then of that question the Apostle has briefly expounded, when he says, “For though there be who are called gods, whether in heaven or in earth, as there are gods many and lords many; yet we have one God the Father, from whom are all, and we in Him; and one Lord Jesus Christ, by whom are all things, and we by Him.”
