But he who says that there should have been neither copulation nor generation but for sin, virtually says that man's sin was necessary to complete the number of the saints. For if these two by not sinning should have continued to live alone, because, as is supposed, they could not have begotten children had they not sinned, then certainly sin was necessary in order that there might be not only two but many righteous men. And if this cannot be maintained without absurdity, we must rather believe that the number of the saints fit to complete this most blessed city would have been as great though no one had sinned, as it is now that the grace of God gathers its citizens out of the multitude of sinners, so long as the children of this world generate and are generated.[118] And therefore that marriage, worthy of the happiness of Paradise, should have had desirable fruit without the shame of lust, had there been no sin. But how that could be, there is now no example to teach us. Nevertheless, it ought not to seem incredible that one member might serve the will without lust then, since so many serve it now. Do we now move our feet and hands when we will to do the things we would by means of these members? do we meet with no resistance in them, but perceive that they are ready servants of the will, both in our own case and in that of others, and especially of artisans employed in mechanical operations, by which the weakness and clumsiness of nature become, through industrious exercise, wonderfully dexterous? and shall we not believe that, like as all those members obediently serve the will, so also should the members have discharged the function of generation, though lust, the award of disobedience, had been awanting? Did not Cicero, in discussing the difference of governments in his _De Republica_, adopt a simile from human nature, and say that we command our bodily members as children, they are so obedient; but that the vicious parts of the soul must be treated as slaves, and be coerced with a more stringent authority? And no doubt, in the order of nature, the soul is more excellent than the body; and yet the soul commands the body more easily than itself. Nevertheless this lust, of which we at present speak, is the more shameful on this account, because the soul is therein neither master of itself, so as not to lust at all, nor of the body, so as to keep the members under the control of the will; for if they were thus ruled, there should be no shame. But now the soul is ashamed that the body, which by nature is inferior and subject to it, should resist its authority. For in the resistance experienced by the soul in the other emotions there is less shame, because the resistance is from itself, and thus, when it is conquered by itself, itself is the conqueror, although the conquest is inordinate and vicious, because accomplished by those parts of the soul which ought to be subject to reason, yet, being accomplished
