2. That they were fair. Moses does not deem it worthy of condemnation that regard was had to beauty, in the choice of wives; but that mere lust reigned. For marriage is a thing too sacred to allow that men should be induced to it by the lust of the eyes. (259) For this union is inseparable comprising all the parts of life; as we have before seen, that the woman was created to be a helper of the man. Therefore our appetite becomes brutal, when we are so ravished with the charms of beauty, that those things which are chief are not taken into the account. Moses more clearly describes the violent impetuosity of their lust, when he says, that they took wives of all that they chose; by which he signifies, that the sons of God did not make their choice from those possessed of necessary endowments, but wandered without discrimination, rushing onward according to their lust. We are taught, however, in these words, that temperance is to be used in holy wedlock, and that its profanation is no light crime before God. For it is not fornication which is here condemned in the sons of the saints, but the too great indulgence of license in choosing themselves wives. And truly, it is impossible but that, in the succession of time, the sons of God should degenerate when they thus bound themselves in the same yoke with unbelievers. And this was the extreme policy of Balaam; that, when the power of cursing was taken from him, he commanded women to be privily sent by the Midianites, who might seduce the people of God to impious defection. Thus, as in the sons of the patriarchs, of whom Moses now treats, the forgetfulness of that grace which had been divinely imparted to them was, in itself, a grievous evil, inasmuch as they formed illicit marriages after their own host; a still worse addition was made, when, by mingling themselves with the wicked, they profaned the worship of God, and fell away from the faith; a corruption which is almost always wont to follow the former.
(259) “ Est autem res sanctior conjugium quam ut oculis ferri homines debeant ad vluptatem coitus.”
