For that line also of which Seth is the father has the name "Dedication" in the seventh generation from Adam, counting Adam. For the seventh from him is Enoch, that is, Dedication. But this is that man who was translated because he pleased God, and who held in the order of the generations a remarkable place, being the seventh from Adam, a number signalized by the consecration of the Sabbath. But, counting from the diverging point of the two lines, or from Seth, he was the sixth. Now it was on the sixth day God made man, and consummated His works. But the translation of Enoch prefigured our deferred dedication; for though it is indeed already accomplished in Christ our Head, who so rose again that He shall die no more, and who was Himself also translated, yet there remains another dedication of the whole house, of which Christ Himself is the foundation, and this dedication is deferred till the end, when all shall rise again to die no more. And whether it is the house of God, or the temple of God, or the city of God, that is said to be dedicated, it is all the same, and equally in accordance with the usage of the Latin language. For Virgil himself calls the city of widest empire "the house of Assaracus,"190 meaning the Romans, who were descended through the Trojans from Assaracus. He also calls them the house of Æneas, because Rome was built by those Trojans who had come to Italy under Æneas.191 For that poet imitated the sacred writings, in which the Hebrew nation, though so numerous, is called the house of Jacob.
20. How it is that Cain's line terminates in the eighth generation, while Noah, though descended from the same father, Adam, is found to be the tenth from him.
Some one will say, If the writer of this history intended, in enumerating the generations from Adam through his son Seth, to descend through them to Noah, in whose time the deluge occurred, and from him again to trace the connected generations down to Abraham, with whom Matthew begins the pedigree of Christ the eternal King of the city of God, what did he intend by enumerating the generations from Cain, and to what terminus did he mean to trace them? We reply, To the deluge, by which the whole stock of the earthly city was destroyed, but repaired by the sons of Noah. For the earthly city and community of men who live after the flesh will never fail until the end of this world, of which our Lord says, "The children of this world generate, and are generated."192 But the city of God, which sojourns in this world, is conducted by regeneration to the world to come, of which the children neither generate nor are generated. In this world generation is common to both cities; though even now the city of God has many thousand citizens who abstain from the act of generation; yet the other city also has some citizens who imitate these, though erroneously. For to that city belong also those who have erred from the faith, and introduced divers heresies; for they live according to man, not according to God. And the Indian gymnosophists, who are said to philosophize in the solitudes of India in a state of nudity, are its citizens; and they abstain from marriage. For continence is not a good thing, except when it is practised in the faith of the highest good, that is, God. Yet no one is found to have practised it before the deluge; for indeed even Enoch himself, the seventh from Adam, who is said to have been translated without dying, begat sons and daughters before he was translated, and among these was Methuselah, by whom the succession of the recorded generations is maintained.
Why, then, is so small a number of Cain's generations registered, if it was proper to trace them to the deluge, and if there was no such delay of the date of puberty as to preclude the hope of offspring for a hundred or more years? For if the author of this book had not in view some one to whom he might rigidly trace the series of generations, as he designed in those which sprang from Seth's seed to descend to Noah, and thence to start again by a rigid order, what need was there of omitting the first-born sons for the sake of descending to Lamech, in whose sons that line terminates, – that is to say, in the eighth generation from Adam, or the seventh from Cain, – as if from this point he had wished to pass on to another series, by which he might reach either the Israelitish people, among whom the earthly Jerusalem presented a prophetic figure of the heavenly city, or to Jesus Christ, "according to the flesh, who is over all, God blessed for ever,"193 the Maker and Ruler of the heavenly city? What, I say, was the need of this, seeing that the whole of Cain's posterity were destroyed in the deluge? From this it is manifest that they are the first-born sons who are registered in this genealogy. Why, then, are there so few of them? Their numbers in the period before the deluge must have been greater, if the date of puberty bore no proportion to their longevity, and they had children before they were a hundred years old. For supposing they were on an average thirty years old when they began to beget children, then, as there are eight generations, including Adam and Lamech's children, 8 times 30 gives 240 years; did they then produce no more children in all the rest of the time before the deluge? With what intention, then, did he who wrote this record make no mention of subsequent generations? For from Adam to the deluge there are reckoned, according to our copies of Scripture, 2262 years,194 and according to the Hebrew text, 1656 years. Supposing, then, the smaller number to be the true one, and subtracting from 1656 years 240, is it credible that during the remaining 1400 and odd years until the deluge the posterity of Cain begat no children?
But let any one who is moved by this call to mind that when I discussed the question, how it is credible that those primitive men could abstain for so many years from begetting children, two modes of solution were found, – either a puberty late in proportion to their longevity, or that the sons registered in the genealogies were not the first-born, but those through whom the author of the book intended to reach the point aimed at, as he intended to reach Noah by the generations of Seth. So that, if in the generations of Cain there occurs no one whom the writer could make it his object to reach by omitting the first-borns and inserting those who would serve such a purpose, then we must have recourse to the supposition of late puberty, and say that only at some age beyond a hundred years they became capable of begetting children, so that the order of the generations ran through the first-borns, and filled up even the whole period before the deluge, long though it was. It is, however, possible that, for some more secret reason which escapes me, this city, which we say is earthly, is exhibited in all its generations down to Lamech and his sons, and that then the writer withholds from recording the rest which may have existed before the deluge. And without supposing so late a puberty in these men, there might be another reason for tracing the generations by sons who were not first-borns, viz. that the same city which Cain built, and named after his son Enoch, may have had a widely extended dominion and many kings, not reigning
