On Marriage and Concupiscence

Now observe what follows, as he goes on to say: “If, before sin, God created a source from which men should be born, but the devil a source from which parents were disturbed, then beyond a doubt holiness must be ascribed to those that are born, and guilt to those that produce. Since, however, this would be a most manifest condemnation of marriage; remove, I pray you, this view from the midst of the churches, and really believe that all things were made by Jesus Christ, and that without Him nothing was made.” He so speaks here, as if he would make us say, that there is a something in man's substance which was created by the devil. The devil persuaded evil as a sin; he did not create it as a nature. No doubt he persuaded nature for man is nature; and therefore by his persuasion he corrupted it. He who wounds a limb does not, of course, create it, but he injures it. Those wounds, indeed, which are inflicted on the body produce lameness in a limb, or difficulty of motion; but they do not affect the virtue whereby a man becomes righteous: that wound, however, which has the name of sin, wounds the very life, which was being righteously lived. This wound was at that fatal moment of the fall inflicted by the devil to a vastly wider and deeper extent than are the sins which are known among men. Whence it came to pass, that our nature having then and there been deteriorated by that great sin of the first man, not only was made a sinner, but also generates sinners; and yet the very weakness, under which the virtue of a holy life has drooped and died, is not really nature, but corruption; precisely as a bad state of health is not a bodily substance or nature, but disorder; very often, indeed, if not always, the ailing character of parents is in a certain way implanted, and reappears in the bodies of their children.
