Saint Augustine (354-430)

Of Marriage and Concupiscence

Translated by Peter Holmes

Book I

Chapter 23

Now this concupiscence, this law of sin which dwells in our members, to which the law of righteousness forbids allegiance, saying in the words of the apostle, “Let not sin, therefore, reign in your mortal body, that ye should obey it in the lusts thereof; neither yield ye your members as instruments of unrighteousness unto sin”:—this concupiscence, I say, which is cleansed only by the sacrament of regeneration, does undoubtedly, by means of natural birth, pass on the bond of sin to a man’s posterity, unless they are themselves loosed from it by regeneration. In the case, however, of the regenerate, concupiscence is not itself sin any longer, whenever they do not consent to it for illicit works, and when the members are not applied by the presiding mind to perpetrate such deeds. So that, if what is enjoined in one passage, “Thou shalt not covet,” is not kept, that at any rate is observed which is commanded in another place, “Thou shalt not go after thy concupiscences.” Inasmuch, however, as by a certain manner of speech it is called sin, since it arose from sin, and, when it has the upper hand, produces sin, the guilt of it prevails in the natural man; but this guilt, by Christ’s grace through the remission of all sins, is not suffered to prevail in the regenerate man, if he does not yield obedience to it whenever it urges him to the commission of evil. As arising from sin, it is, I say, called sin, although in the regenerate it is not actually sin; and it has this designation applied to it, just as speech which the tongue produces is itself called “tongue”; and just as the word “hand” is used in the sense of writing, which the hand produces. In the same way concupiscence is called sin, as producing sin when it conquers the will: so to cold and frost the epithet “sluggish” is given; not as arising from, but as productive of, sluggishness; benumbing us, in fact.

This wound which the devil has inflicted on the human race compels everything which has its birth in consequence of it to be under the devil’s power, as if he were rightly plucking fruit off his own tree. Not as if man’s nature, which is only of God, came from him, but sin alone, which is not of God. For it is not on its own account that man’s nature is under condemnation, because it is the work of God, and therefore laudable; but on account of that condemnable corruption by which it has been vitiated. Now it is by reason of this condemnation that it is in subjection to the devil, who is also in the same damnable state. For the devil is himself an unclean spirit: good, indeed, so far as he is a spirit, but evil as being unclean; for by nature he is a spirit, by the corruption thereof an unclean one. Of these two, the one is of God, the other of himself. His hold over men, therefore, whether of an advanced age or in infancy, is not because they are human, but because they are polluted. He, then, who feels surprise that God’s creature is a subject of the devil, should cease from such feeling. For one creature of God is in subjection to another creature of God, the less to the greater, a human being to an angelic one; and this is not owing to nature, but to a corruption of nature: polluted is the sovereign, polluted also the subject. All this is the fruit of that ancient stock of pollution which he has planted in man; himself being destined to suffer a heavier punishment at the last judgment, as being the more polluted; but at the same time even they who will have to bear a less heavy burden in that condemnation are subjects of him as the prince and author of sin, for there will be no other cause of condemnation than sin.
