12. And he, therefore, that the younger should be avoided, because they are not able to fulfil the requirements of so high a degree of virtue. For youth is prone to fall because the heat of various desires is inflamed by the warmth of glowing youth, and it is the part of a good doctor to keep off the materials of sin. For the first exercise in training the soul is to turn away sin, the second to implant virtue. Yet, since the Apostle knew that Anna, the widow of fourscore years, from her youth was a herald of the works of the Lord, I do not think that he thought that the younger should be excluded from the devotion of widowhood, especially as he said: “It is better to marry than to burn.” For certainly he recommended marriage as a remedy, that she who would else perish might be saved; he did not prescribe the choice that one who could contain should not follow chastity, for it is one thing to succour one who is falling, another to persuade to virtue.
