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,"(4) 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 <greek>aUUels</greek>, 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 rumor, 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.(5) 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."(1) I think he rather speaks of these 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 man have been called angels; for of John it is written:
"Behold, I send my messenger (angel) before Thy face, who shall prepare Thy way."(2) And the prophet Malachi, by a peculiar grace specially communicated to him, was called an angel.(3)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 over-topped 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."(4) 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.
