Nor do we, in saying these things, account wedlock as sin. But, since even the lawful intercourse of the wedded cannot take place without pleasure of the flesh, entrance into a sacred place should be abstained from, because the pleasure itself can by no means be without sin. For he had not been born of adultery or fornication, but of lawful wedlock, who said, Behold I was conceived in iniquities, and in sin my mother brought me forth. For, knowing himself to have been conceived in iniquities, he groaned for having been born in sin, because the tree bears in its branch the vicious humour which it has drawn from its root. Yet in these words he does not call the intercourse of the wedded iniquity in itself, but in truth only the pleasure of the intercourse. For there are many things which are allowed and legitimate, and yet we are to some extent defiled in the doing of them; as often we attack faults with anger, and disturb the tranquillity of our own mind. And, though what is done is right, yet it is not to be approved that the mind is therein disturbed. For instance, he had been angry against the vices of transgressors who said, Mine eye is disturbed because of anger. For, since the mind cannot, unless it be tranquil, lift itself up to the light of contemplation, he grieved that his eye was disturbed in anger, because, though assailing evil doings from above, he still could not help being confused and disturbed from contemplation of the highest things. And therefore his anger against vice is laudable, and yet it troubles him, because he felt that he had incurred some guilt in being disturbed. Lawful copulation of the flesh ought therefore to be for the purpose of offspring, not of pleasure; and intercourse of the flesh should be for the sake of producing children, and not a satisfaction of frailties. If, then, any one makes use of his wife not as seized by the desire of pleasure, but only for the sake of producing children, he certainly, with regard to entering the church or taking the mystery of the body and blood of the Lord, is to be left to his own judgment, since by us he ought not to be prohibited from receiving it who knows no burning though in the midst of fire. But, when not the love of producing offspring but pleasure dominates in the act of intercourse, married persons have something to mourn over in their intercourse. For holy preaching concedes them this, and yet in the very concession shakes the mind with fear. For, when the Apostle Paul said, Who cannot contain let him have his own wife, he straightway took care to add, But I speak this by way of indulgence, not by way of command. For what is just and right is not indulged: what he spoke of as indulged he shewed to be a fault.
