But if the Creator is truly loved, that is, if He Himself is loved and not another thing in His stead, He cannot be evilly loved; for love itself is to be ordinately loved, because we do well to love that which, when we love it, makes us live well and virtuously. So that it seems to me that it is a brief but true definition of virtue to say, it is the order of love; and on this account, in the Canticles, the bride of Christ, the city of God, sings, "Order love within me."203 It was the order of this love, then, this charity or attachment, which the sons of God disturbed when they forsook God, and were enamoured of the daughters of men.204 And by these two names (sons of God and daughters of men) the two cities are sufficiently distinguished. For though the former were by nature children of men, they had come into possession of another name by grace. For in the same Scripture in which the sons of God are said to have loved the daughters of men, they are also called angels of God; whence many suppose that they were not men but angels.
23. Whether we are to believe that angels, who are of a spiritual substance, fell in love with the beauty of women, and sought them in marriage, and that from this connection giants were born.
In the third book of this work (c. 5) we made a passing reference to this question, but did not decide whether angels, inasmuch as they are spirits, could have bodily intercourse with women. For it is written, "Who maketh His angels spirits,"205 that is, He makes those who are by nature spirits His angels by appointing them to the duty of bearing His messages. For the Greek word ἄγγελος, which in Latin appears as "angelus," means a messenger. But whether the Psalmist speaks of their bodies when he adds, "and His ministers a flaming fire," or means that God's ministers ought to blaze with love as with a spiritual fire, is doubtful. However, the same trustworthy Scripture testifies that angels have appeared to men in such bodies as could not only be seen, but also touched. There is, too, a very general rumour, which many have verified by their own experience, or which trustworthy persons who have heard the experience of others corroborate, that sylvans and fauns, who are commonly called "incubi," had often made wicked assaults upon women, and satisfied their lust upon them; and that certain devils, called Duses by the Gauls, are constantly attempting and effecting this impurity is so generally affirmed, that it were impudent to deny it.206 From these assertions, indeed, I dare not determine whether there be some spirits embodied in an aerial substance (for this element, even when agitated by a fan, is sensibly felt by the body), and who are capable of lust and of mingling sensibly with women; but certainly I could by no means believe that God's holy angels could at that time have so fallen, nor can I think that it is of them the Apostle Peter said, "For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment."207 I think he rather speaks of those who first apostatized from God, along with their chief the devil, who enviously deceived the first man under the form of a serpent. But the same holy Scripture affords the most ample testimony that even godly men have been called angels; for of John it is written: "Behold, I send my messenger (angel) before Thy face, who shall prepare Thy way."208 And the prophet Malachi, by a peculiar grace specially communicated to him, was called an angel.209
But some are moved by the fact that we have read that the fruit of the connection between those who are called angels of God and the women they loved were not men like our own breed, but giants; just as if there were not born even in our own time (as I have mentioned above) men of much greater size than the ordinary stature. Was there not at Rome a few years ago, when the destruction of the city now accomplished by the Goths was drawing near, a woman, with her father and mother, who by her gigantic size overtopped all others? Surprising crowds from all quarters came to see her, and that which struck them most was the circumstance that neither of her parents were quite up to the tallest ordinary stature. Giants therefore might well be born, even before the sons of God, who are also called angels of God, formed a connection with the daughters of men, or of those living according to men, that is to say, before the sons of Seth formed a connection with the daughters of Cain. For thus speaks even the canonical Scripture itself in the book in which we read of this; its words are: "And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, that the sons of God saw the daughters of men that they were fair [good]; and they took them wives of all which they chose. And the Lord God said, My Spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years. There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became the giants, men of renown."210 These words of the divine book sufficiently indicate that already there were giants in the earth in those days, in which the sons of God took wives of the children of men, when they loved them because they were good, that is, fair. For it is the custom of this Scripture to call those who are beautiful in appearance "good." But after this connection had been formed, then too were giants born. For the words are: "There were giants in the earth in those days, and also after that, when the sons of God came in unto the daughters of men." Therefore there were giants both before, "in those days," and "also after that." And the words, "they bare children to them," show plainly enough that before the sons of God fell in this fashion they begat children to God, not to themselves, – that is to say, not moved by the lust of sexual intercourse, but discharging the duty of propagation, intending to produce not a family to gratify their own pride, but citizens to people the city of God; and to these they as God's angels would bear the message, that they should place their hope in God, like him who was born of Seth the son of resurrection, and who hoped to call on the name of the Lord God, in which hope they and their offspring would be co-heirs of eternal blessings, and brethren in the family of which God is the Father.
But that those angels were not angels in the sense of not being men, as some suppose, Scripture itself decides, which unambiguously declares that they were men. For when it had first been stated that "the angels of God saw the daughters of men that they were fair, and they took them wives of all which they chose," it was immediately added, "And the Lord God said, My Spirit shall not always strive with these men, for that they also are flesh." For by the Spirit of God they had been made angels of God, and sons of God; but declining towards lower things, they are called men, a name of nature, not of grace; and they are called flesh, as deserters of the Spirit, and by their desertion deserted [by Him]. The Septuagint indeed calls them both angels of God and sons of God, though all the copies do not show this, some having only the name "sons of God." And Aquila, whom the Jews prefer to the other interpreters,211 has translated neither angels of God nor sons of God, but sons of gods. But both are correct. For they were both sons of God, and thus brothers of their own fathers, who were children of the same God; and they were sons of gods, because begotten by gods, together with whom they themselves also were gods, according to that expression of the psalm: "I have said, Ye are gods, and all of you are children of the Most High."212 For the Septuagint translators are justly believed to have received the Spirit of prophecy; so that, if they made any alterations under His authority, and did not adhere to a strict translation, we could not doubt that this was divinely dictated. However, the Hebrew word may be said to be ambiguous, and to be susceptible of either translation, "sons of God," or "sons of gods."
Let us omit, then, the fables of those scriptures which are called apocryphal, because
