Moral Treatises of St. Augustin: Section 9

9. It is indeed a greater fight of patience, when it is not a visible enemy that by persecution and rage would urge us into crime which enemy may openly and in broad day be by not consenting overcome; but the devil himself, (he who doth likewise by means of the children of infidelity, as by his vessels, persecute the children of light) doth by himself hiddenly attack us, by his rage putting us on to do or say something against God. As such had holy Job experience of him, by both temptations vexed, but in both through steadfast strength of patience and arms of piety unconquered. For first, his body being left unhurt, he lost all that he had, in order that the mind, before excruciation of the flesh, might through withdrawal of the things which men are wont to prize highly, be broken, and he might say something against God upon loss of the things for the sake of which he was thought to worship Him. He was smitten also with sudden bereavement of all his sons so that whom he had begotten one by one he should lose all at once, as though their numerousness had been not for the adorning of his felicity, but for the increasing of his calamity. But where, having endured these things, he remained immovable in his God, he cleaved to His will, Whom it was not possible to lose but by his own will; and in place of the things he had lost he held Him who took them away, in Whom he should find what should never be lost. For He that took them away was not that enemy who had will of hurting, but He who had given to that enemy the power of hurting. The enemy next attacked also the body, and now not those things which were in the man from without, but the man himself, in whatever part he could, he smote. From the head to the feet were burning pains, were crawling worms, were running sores; still in the rotting body the mind remained entire, and horrid as were the tortures of the consuming flesh, with inviolate piety and uncorrupted patience it endured them all. There stood the wife, and instead of giving her husband any help, was suggesting blasphemy against God. For we are not to think that the devil, in leaving her when he took away the sons, went to work as one unskilled in mischief: rather, how necessary she was to the tempter, he had already learned in Eve. But now he had not found a second Adam whom he might take by means of a woman. More cautious was Job in his hours of sadness, than Adam in his bowers of gladness, the one was overcome in the midst of pleasant things, the other overcame in the midst of pains; the one consented to that which seemed delightsome, this other quailed not in torments most affrightsome. There stood his friends too, not to console him in his evils, but to suspect evil in him. For while he suffered so great sorrows, they believed him not innocent, nor did their tongue forbear to say that which his conscience had not to say; that so amid ruthless tortures of the body, his mind also might be beaten with truthless reproaches. But he, bearing in his flesh his own pains, in his heart others’ errors, reproved his wife for her folly, taught his friends wisdom, preserved patience in each and all.
