City of God, Book XVI
Chapter 25. Of Sarah’s Handmaid, Hagar, Whom She Herself Wished to Be Abraham’s Concubine
And here follow the times of Abraham’s sons, the one by Hagar the bond maid, the other by Sarah the free woman, about whom we have already spoken in the previous book. As regards this transaction, Abraham is in no way to be branded as guilty concerning this concubine, for he used her for the begetting of progeny, not for the gratification of lust; and not to insult, but rather to obey his wife, who supposed it would be solace of her barrenness if she could make use of the fruitful womb of her handmaid to supply the defect of her own nature, and by that law of which the apostle says, “Likewise also the husband hath not power of his own body, but the wife,” could, as a wife, make use of him for childbearing by another, when she could not do so in her own person. Here there is no wanton lust, no filthy lewdness. The handmaid is delivered to the husband by the wife for the sake of progeny, and is received by the husband for the sake of progeny, each seeking, not guilty excess, but natural fruit. And when the pregnant bond woman despised her barren mistress, and Sarah, with womanly jealousy, rather laid the blame of this on her husband, even then Abraham showed that he was not a slavish lover, but a free begetter of children, and that in using Hagar he had guarded the chastity of Sarah his wife, and had gratified her will and not his own,—had received her without seeking, had gone in to her without being attached, had impregnated without loving her,—for he says, “Behold thy maid is in thy hands: do to her as it pleaseth thee;” a man able to use women as a man should,—his wife temperately, his handmaid compliantly, neither intemperately!
Chapter 26.—Of God’s Attestation to Abraham, by Which He Assures Him, When Now Old, of a Son by the Barren Sarah, and Appoints Him the Father of the Nations, and Seals His Faith in the Promise by the Sacrament of Circumcision.
After these things Ishmael was born of Hagar; and Abraham might think that in him was fulfilled what God had promised him, saying, when he wished to adopt his home-born servant, “This shall not be thine heir; but he that shall come forth of thee, he shall be thine heir.” Therefore, lest he should think that what was promised was fulfilled in the handmaid’s son, “when Abram was ninety years old and nine, God appeared to him, and said unto him, I am God; be well-pleasing in my sight, and be without complaint, and I will make my covenant between me and thee, and will fill thee exceedingly.”
Here there are more distinct promises about the calling of the nations in Isaac, that is, in the son of the promise, by which grace is signified, and not nature; for the son is promised from an old man and a barren old woman. For although God effects even the natural course of procreation, yet where the agency of God is manifest, through the decay or failure of nature, grace is more plainly discerned. And because this was to be brought about, not by generation, but by regeneration, circumcision was enjoined now, when a son was promised of Sarah. And by ordering all, not only sons, but also home-born and purchased servants to be circumcised, he testifies that this grace pertains to all. For what else does circumcision signify than a nature renewed on the putting off of the old? And what else does the eighth day mean than Christ, who rose again when the week was completed, that is, after the Sabbath? The very names of the parents are changed: all things proclaim newness, and the new covenant is shadowed forth in the old. For what does the term old covenant imply but the concealing of the new? And what does the term new covenant imply but the revealing of the old? The laughter of Abraham is the exultation of one who rejoices, not the scornful laughter of one who mistrusts. And those words of his in his heart, “Shall a son be born to me that am an hundred years old? and shall Sarah, that is ninety years old, bear?” are not the words of doubt, but of wonder. And when it is said, “And I will give to thee, and to thy seed after thee, the land in which thou art a stranger, all the land of Canaan, for an everlasting possession,” if it troubles any one whether this is to be held as fulfilled, or whether its fulfilment may still be looked for, since no kind of earthly possession can be everlasting for any nation whatever, let him know that the word translated everlasting, by our writers is what the Greeks term αἰώνιον , which is derived from αἰὼ·ν , the Greek for sæculum, an age. But the Latins have not ventured to translate this by secular, lest they should change the meaning into something widely different. For many things are called secular which so happen in this world as to pass away even in a short time; but what is termed αἰώνιον either has no end, or lasts to the very end of this world.
Chapter 27.—Of the Male, Who Was to Lose His Soul If He Was Not Circumcised on the Eighth Day, Because He Had Broken God’s Covenant.
When it is said, “The male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people, because he hath broken my covenant,” some may be troubled how that ought to be understood, since it can be no fault of the infant whose life it is said must perish; nor has the covenant of God been broken by him, but by his parents, who have not taken care to circumcise him. But even the infants, not personally in their own life, but according to the common origin of the human race, have all broken God’s covenant in that one in whom all have sinned. Now there are many things called God’s covenants besides those two great ones, the old and the new, which any one who pleases may read and know. For the first covenant, which was made with the first man, is just this: “In the day ye eat thereof, ye shall surely die.” Whence it is written in the book called Ecclesiasticus, “All flesh waxeth old as doth a garment. For the covenant from the beginning is, Thou shall die the death.” Now, as the law was more plainly given afterward, and the apostle says, “Where no law is, there is no prevarication,” on what supposition is what is said in the psalm true, “I accounted all the sinners of the earth prevaricators,” except that all who are held liable for any sin are accused of dealing deceitfully (prevaricating) with some law? If on this account, then, even the infants are, according to the true belief, born in sin, not actual but original, so that we confess they have need of grace for the remission of sins, certainly it must be acknowledged that in the same sense in which they are sinners they are also prevaricators of that law which was given in Paradise, according to the truth of both scriptures, “I accounted all the sinners of the earth prevaricators,” and “Where no law is, there is no prevarication.”
And thus, because circumcision was the sign of regeneration, and the infant, on account of the original sin by which God’s covenant was first broken, was not undeservedly to lose his generation unless delivered by regeneration, these divine words are to be understood as if it had been said, Whoever is not born again, that soul shall perish from his people, because he hath broken my covenant, since he also has sinned in Adam with all others. For had He said, Because he hath broken this my covenant, He would have compelled us to understand by it only this of circumcision; but since He has not expressly said what covenant the infant has broken, we are free to understand Him as speaking of that covenant of which the breach can be ascribed to an infant. Yet if any one contends that it is said of nothing else than circumcision, that in it the infant has broken the covenant of God because he is not circumcised, he must seek some method of explanation by which it may be understood without absurdity (such as this) that he has broken the covenant, because it has been broken in him although not by him. Yet in this case also it is to be observed that the soul of the infant, being guilty of no sin of neglect against itself, would perish unjustly, unless original sin rendered it obnoxious to punishment.
