When, therefore, we look for the city of God in these seventy-two nations, we cannot affirm that while they had but one lip, that is, one language, the human race had departed from the worship of the true God, and that genuine godliness had survived only in those generations which descend from Shem through Arphaxad and reach to Abraham; but from the time when they proudly built a tower to heaven, a symbol of godless exaltation, the city or society of the wicked becomes apparent. Whether it was only disguised before, or non-existent; whether both cities remained after the flood,—the godly in the two sons of Noah who were blessed, and in their posterity, and the ungodly in the cursed son and his descendants, from whom sprang that mighty hunter against the Lord,—is not easily determined. For possibly—and certainly this is more credible—there were despisers of God among the descendants of the two sons, even before Babylon was founded, and worshippers of God among the descendants of Ham. Certainly neither race was ever obliterated from earth. For in both the Psalms in which it is said, "They are all gone aside, they are altogether become filthy; there is none that doeth good, no, not one," we read further, "Have all the workers of iniquity no knowledge? who eat up my people as they eat bread, and call not upon the Lord." There was then a people of God even at that time. And therefore the words, "There is none that doeth good, no, not one," were said of the sons of men, not of the sons of God. For it had been previously said, "God looked down from heaven upon the sons of men, to see if any understood and sought after God;" and then follow the words which demonstrate that all the sons of men, that is, all who belong to the city which lives according to man, not according to God, are reprobate.
