108. Moses, therefore, concludes that, because the sons of God had forsaken the worship and Word of God and departed from the precepts of their parents, thereupon to fall into sensuality and lust, and to take to wife whom they pleased, they also became violent and appropriated the goods of others. The world cannot do otherwise. When it has forsaken God, it worships the devil; when it has despised the Word and fallen into idolatry, it rushes forth into all sins of passion, in which fierceness of anger and fierceness of desire by turns are aroused, and thus all the appetites are thrown into a state of the greatest disorder. When the righteous reprove this, the result is resentment and violence against them.
109. The sin of the flood, then, embraces everything that may be called sin, by the first as well as the second table. Wicked men first depart from God through unbelief; then they disregard obedience to parents, and finally become murderers, adulterers, etc.
110. I mention this to the end that no one may believe that sex or the marriage estate in themselves are to blame. It is chiefly transgression of God's commandments and disobedience to parents which are condemned. Owing to absence of fellowship between the Cainites and the true Church, pious parents desired also social separation from the Cainites, for fear they might be perverted by the manners of ungodly wives. But God's command being neglected, and the authority of parents despised, the younger generation lapsed into the passions of concupiscence and vehemence. In this way the honor of sex and the dignity of matrimony are conserved: accusation is brought solely against the unrighteousness which first departs from God and then manifests itself in injuring the saints.
111. This is the teaching of the words: "The sons of God saw the daughters of men that they were fair." Why did they not see the daughters of God and desire those in the Church and possess the promise of the seed? Are they not convicted of contempt for the sisters of their own generation, that is the true Church, and of mingling with the carnal and impious generation of Cain? They despise the simplicity and reserve of their sisters and prefer the smiles, the dress, the wiles of the daughters of Cain; the latter they crave and cultivate, the former they treat either with neglect or dishonor.
112. With such eyes as Eve viewed the apples when she fell into sin, the sons of God viewed the daughters of men. Eve had seen the forbidden tree before that, but with eyes of faith looking back to God's commandment; for that reason she did not crave, but rather she fled from the same. When, however, the eyes of faith were dimmed and she beheld the tree solely with carnal eyes, she stretched out her hand with desire and invited also Adam, her husband.
