Augustine of Hippo

The reason for this break in the narrative [in the description of the genealogies to the flood] was, I take it, that the writer, as though bidden by God, was unwilling to have the beginning of world chronology reckoned from the earthly city (that is, from the generation of Cain), and so he deliberately went back to Adam for a new beginning. If we ask why this return to recapitulate was made immediately after mentioning Seth's son, the man who hoped to call upon the name of the Lord God, the answer must be that this was the proper way to present the two cities. The one begins and ends with a murderer, for Lamech, too, as he admitted to his two wives, was a murderer. The other city begins with the man who hoped to call upon the name of the Lord God, for the invocation of God is the whole and the highest preoccupation of the city of God during its pilgrimage in this world. It is symbolized in the one "man" (Enosh) born of the "resurrection" (Seth) of the man who was slain (Abel). That one man in fact is a symbol of the unity of the whole heavenly city, which is not yet in the fullness that it is destined to reach and which is adumbrated in this prophetic figure.

In the third book of this work 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 makes His angels spirits," 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 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. 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." [2 Peter 2:4] 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 men have been called angels; for of John it is written: "Behold, I send my messenger (angel) before Your face, who shall prepare Your way." [Mark 1:2] And the prophet Malachi, by a peculiar grace specially communicated to him, was called an angel. [Malachi 2:7]

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." 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 begot 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, 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, You are gods, and all of you are children of the Most High." 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 their obscure origin was unknown to the fathers from whom the authority of the true Scriptures has been transmitted to us by a most certain and well-ascertained succession. For though there is some truth in these apocryphal writings, yet they contain so many false statements, that they have no canonical authority. We cannot deny that Enoch, the seventh from Adam, left some divine writings, for this is asserted by the Apostle Jude in his canonical epistle. But it is not without reason that these writings have no place in that canon of Scripture which was preserved in the temple of the Hebrew people by the diligence of successive priests; for their antiquity brought them under suspicion, and it was impossible to ascertain whether these were his genuine writings, and they were not brought forward as genuine by the persons who were found to have carefully preserved the canonical books by a successive transmission. So that the writings which are produced under his name, and which contain these fables about the giants, saying that their fathers were not men, are properly judged by prudent men to be not genuine; just as many writings are produced by heretics under the names both of other prophets, and more recently, under the names of the apostles, all of which, after careful examination, have been set apart from canonical authority under the title of Apocrypha. There is therefore no doubt that, according to the Hebrew and Christian canonical Scriptures, there were many giants before the deluge, and that these were citizens of the earthly society of men, and that the sons of God, who were according to the flesh the sons of Seth, sunk into this community when they forsook righteousness. Nor need we wonder that giants should be born even from these. For all of their children were not giants; but there were more then than in the remaining periods since the deluge. And it pleased the Creator to produce them, that it might thus be demonstrated that neither beauty, nor yet size and strength, are of much moment to the wise man, whose blessedness lies in spiritual and immortal blessings, in far better and more enduring gifts, in the good things that are the peculiar property of the good, and are not shared by good and bad alike. It is this which another prophet confirms when he says, "These were the giants, famous from the beginning, that were of so great stature, and so expert in war. Those did not the Lord choose, neither gave He the way of knowledge unto them; but they were destroyed because they had no wisdom, and perished through their own foolishness."

Undoubtedly the ark is a symbol of the city of God on its pilgrimage in history. It is a figure of the church that was saved by the wood on which there hung the “Mediator between God and men, himself man, Jesus Christ.” Even the very measurements of length, height and breadth of the ark are meant to point to the reality of the human body into which he came as it was foretold that he would come. It will be recalled that the length of a normal body from head to foot is six times the breadth from one side to the other and ten times the thickness from back to front. Measure a man who is lying on the ground, either prone or supine. He is six times as long from head to foot as he is wide from left to right or right to left, and he is ten times as long as he is high from the ground up. That is why the ark was made three hundred cubits in length, fifty in breadth and thirty in height. As for the door in the side, that surely, symbolizes the open wound made by the lance in the side of the Crucified—the door by which those who come to him enter in, in the sense that believers enter the church by means of the sacraments that issued from that wound. It was ordered that the ark be made out of squared timbers—a symbol of the foursquare stability of a holy life, which, like a cube, stands firm however it is turned. So it is with every other detail of the ark’s construction. They are all symbols of something in the church.
