"They say also," says he, "that sexual impulse and the intercourse of married people were devised by the devil, and that therefore those who are born innocent are guilty, and that it is the work of the devil, not of God, that they are born of this diabolical intercourse. And this, without any ambiguity, is Manicheism." Nay, as I say that marriage was appointed by God for the sake of the ordinance of the begetting of children, so I say that the propagation of children to be begotten could not have taken place without sexual impulse, and without intercourse of husband and wife, even in Paradise, if children were begotten there. But whether such impulse and intercourse would have existed, as is now the case with shameful lust, if no one had sinned, here is the question concerning which I shall argue hereafter, if God will.
