(25) Why does he say, Sarah afflicted her? (#Ge 16:6). The literal meaning of the words is plain: but if we look to the inner sense of them, they contain a principle of this kind. It is not every affliction that is injurious, but there are even some occasions when they are salutary; and this is experienced by sick men at the hands of physicians, and by boys under their tutors, and by foolish people from those who correct them so as to bring them to wisdom. And this I can by no means consent to call affliction, but rather the salvation and benefit of both soul and body. Now a part of such benefit wisdom affords to the circle of encyclical knowledge; rightly admonishing the soul which is devoted to an abundance of discipline, and which is pregnant with sophism, not to rebel as if it had acquired some great and excellent good, but to acquiesce and venerate that superior and more excellent nature as its genuine mistress, in whose power is constancy itself, and authority over all things.
