XXXI. (175) Thus, therefore, there is a certain description of affliction which is profitable, so that its very most humiliating form, even slavery, is accounted a great good. And there is a father who is recorded in the sacred writings as having prayed for this, for his son, namely, the most excellent Isaac for the foolish Esau; (176) for he says somewhere, "By thy sword shalt thou live, and thou shalt serve thy Brother."[Ge 27:40.] Judging that destiny to be the most advantageous one for a man who had chosen war rather than peace, and who was as it were constantly armed and engaged in battle, by reason of the sedition and disorder constantly existing in his soul, the destiny namely of being a subject and a servant, and of obeying all the commands which the lover of temperance should lay upon him. (177) And it is from this consideration, as it appears to me that one of the disciples of Moses, by name the peaceful, who in his native language is called Solomon, says, "My son, neglect not the instruction of God, and be not grieved when thou art reproved by him; for whom the Lord loveth he chasteneth; and scourgeth every son whom he Received."[Pr 3:11.] Thus, then, scourging and reproof are looked upon as good, so that by means of it agreement and relationship with God arise. For what can be more nearly related than a son is to his father, and a father to his son? (178) But that we may not seem to be too prolix connecting one argument with another, we will, besides what we have already said, just add one most evident proof that a certain description of affliction is the work of virtue. For there is such a law a this, "Thou shalt not afflict any widow or orphan, but if thou dost afflict them with wickedness." ... What does this mean? Is it then possible to be afflicted by something else? For if afflictions were the work of wickedness alone, then it would be superfluous to add what would be admitted by all, and which would be understood without any such addition. (179) But, you will most certainly say, I know that men are reproved by virtue, and instructed by wisdom; on which account I do not blame every kind of affliction, but I very greatly admire that which is the work of justice and of the law; for that corrects by means of punishment, but that which proceeds from folly and wickedness and is pernicious, I do, as becomes me, detest, and pronounce real evil. (180) When, therefore, you hear that Hagar was afflicted by Sarah, you must not suppose that any of those things befell her, which arise from rivalry and quarrels among women; for the question is not here about woman, but about minds; the one being practised in the branches of elementary instruction, and the other being devoted to the labours of virtue.
