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."[193] 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.
