Again, if purity is properly opposed to concupiscence, it signifies purity of heart, i.e., mortified concupiscence, because the Law does not prohibit marriage, but concupiscence, adultery, fornication. Therefore celibacy is not purity. For there may be greater purity of heart in a married man, as in Abraham or Jacob, than in most of those who are even truly continent [who even, according to bodily purity, really maintain their chastity]. Lastly, if they understand that celibacy is purity in the sense that it merits justification more than does marriage, we most emphatically contradict it. For we are justified neither on account of virginity nor on account of marriage, but freely for Christ's sake, when we believe that for His sake God is propitious to us. Here perhaps they will exclaim that, according to the manner of Jovinian, marriage is made equal to virginity. But, on account of such clamors we shall not reject the truth concerning the righteousness of faith, which we have explained above. Nevertheless we do not make virginity and marriage equal. For just as one gift surpasses another, as prophecy surpasses eloquence, the science of military affairs surpasses agriculture, and eloquence surpasses architecture, so virginity is a more excellent gift than marriage. And nevertheless, just as an orator is not more righteous before God because of his eloquence than an architect because of his skill in architecture, so a virgin does not merit justification by virginity more than a married person merits it by conjugal duties but each one ought faithfully to serve in his own gift, and to believe that for Christ's sake he receives the remission of sins and by faith is accounted righteous before God. Neither does Christ or Paul praise virginity because it justifies, but because it is freer and less distracted with domestic occupations, in praying, teaching, [writing,] serving. For this reason Paul says, 1 Cor. 7, 32: He that is unmarried careth for the things which belong to the Lord. Virginity, therefore, is praised on account of meditation and study. Thus Christ does not simply praise those who make themselves eunuchs, but adds, for the kingdom of heaven's sake, i.e., that they may have leisure to learn or teach the Gospel; for He does not say that virginity merits the remission of sins or salvation.
