But that the woman was made for him out of his own side—here too it was sufficiently signified how dear the union of husband and wife ought to be. These works of God are, to be sure, unusual precisely because they were the first. But those who do not believe these things ought to believe that no marvels have ever been wrought; for these very things, if they were begotten by the accustomed course of nature, would not be called marvels. Yet what is begotten to no purpose under so great a governance of divine providence, even though its cause lies hidden? A certain sacred psalm says: Come and see the works of the Lord, what marvels He has set upon the earth. Why, then, the woman was made out of the man's side, and what this—in a certain way the first marvel—prefigured, will be told in another place, so far as God shall help me.
Now, since this book must be closed, let us hold that in this first man, who was made at the beginning, there had arisen in the human race—not yet indeed according to open manifestation, but already according to God's foreknowledge—two societies, as it were, two cities. For from him were to come men, some to be joined with the evil angels in punishment, others with the good in reward, by God's hidden but nevertheless just judgment. For since it is written: All the ways of the Lord are mercy and truth, neither can His grace be unjust, nor His justice cruel.
