But so long as the will retains under its authority the other members, without which the members excited by lust to resist the will cannot accomplish what they seek, chastity is preserved, and the delight of sin foregone. And certainly, had not culpable disobedience been visited with penal disobedience, the marriage of Paradise should have been ignorant of this struggle and rebellion, this quarrel between will and lust, that the will may be satisfied and lust restrained, but those members, like all the rest, should have obeyed the will. The field of generation[119] should have been sown by the organ created for this purpose, as the earth is sown by the hand. And whereas now, as we essay to investigate this subject more exactly, modesty hinders us, and compels us to ask pardon of chaste ears, there would have been no cause to do so, but we could have discoursed freely, and without fear of seeming obscene, upon all those points which occur to one who meditates on the subject. There would not have been even words which could be called obscene, but all that might be said of these members would have been as pure as what is said of the other parts of the body. Whoever, then, comes to the perusal of these pages with unchaste mind, let him blame his disposition, not his nature; let him brand the actings of his own impurity, not the words which necessity forces us to use, and for which every pure and pious reader or hearer will very readily pardon me, while I expose the folly of that scepticism which argues solely on the ground of its own experience, and has no faith in anything beyond. He who is not scandalized at the apostle's censure of the horrible wickedness of the women who "changed the natural use into that which is against nature,"[120] will read all this without being shocked, especially as we are not, like Paul, citing and censuring a damnable uncleanness, but are explaining, so far as we can, human generation, while with Paul we avoid all obscenity of language.

24. _That if men had remained innocent and obedient in Paradise, the generative organs should have been in subjection to the will as the other members are._

The City of God, Volume II — Part 29

The man, then, would have sown the seed, and the woman received it, as need required, the generative organs being moved by the will, not excited by lust. For we move at will not only those members which are furnished with joints of solid bone, as the hands, feet, and fingers, but we move also at will those which are composed of slack and soft nerves: we can put them in motion, or stretch them out, or bend and twist them, or contract and stiffen them, as we do with the muscles of the mouth and face. The lungs, which are the very tenderest of the viscera except the brain, and are therefore carefully sheltered in the cavity of the chest, yet for all purposes of inhaling and exhaling the breath, and of uttering and modulating the voice, are obedient to the will when we breathe, exhale, speak, shout, or sing, just as the bellows obey the smith or the organist. I will not press the fact that some animals have a natural power to move a single spot of the skin with which their whole body is covered, if they have felt on it anything they wish to drive off,--a power so great, that by this shivering tremor of the skin they can not only shake off flies that have settled on them, but even spears that have fixed in their flesh. Man, it is true, has not this power; but is this any reason for supposing that God could not give it to such creatures as He wished to possess it? And therefore man himself also might very well have enjoyed absolute power over his members had he not forfeited it by his disobedience; for it was not difficult for God to form him so that what is now moved in his body only by lust should have been moved only at will.
