11 For what harm was done to this hero by his bodily infirmity? Or by the absence of protectors? Or by the coming of the dogs? Or the evil proximity of the rich man? Or by the great luxury, haughtiness and arrogance of the latter? Did it enervate him for the contest on behalf of virtue? Did it ruin his fortitude? Nowhere was he harmed at all, but that multitude of sufferings, and the cruelty of the rich man, rather increased his strength, and became the pledge for him of infinite crowns of victory, a means of adding to his rewards, an augmentation of his recompense, and a promise of an increased requital. For he was crowned not merely on account of his poverty, or of his hunger or of his sores, or of the dogs licking them: but because, having such a neighbour as the rich man, and being seen by him every day, and perpetually overlooked he endured this trial bravely and with much fortitude, a trial which added no small flame but in fact a very strong one to the fire of poverty, and infirmity and loneliness.
And, tell me, what was the case of the blessed Paul? For there is nothing to prevent my making mention of him again. Did he not experience innumerable storms of trial? And in what respect was he injured by them? Was he not crowned with victory all the more in consequence—because he suffered hunger, because he was consumed with cold and nakedness, because he was often tortured with the scourge, because he was stoned, because he was cast into the sea? But then some one says he was Paul, and called by Christ. Yet Judas also was one of the twelve, and he too was called of Christ; but neither his being of the twelve nor his call profited him, because he had not a mind disposed to virtue. But Paul although struggling with hunger, and at a loss to procure necessary food, and daily undergoing such great sufferings, pursued with great zeal the road which leads to heaven: whereas Judas although he had been called before him, and enjoyed the same advantages as he did, and was initiated in the highest form of Christian life, and partook of the holy table and that most awful of sacred feasts, and received such grace as to be able to raise the dead, and cleanse the lepers, and cast out devils, and often heard discourses concerning poverty, and spent so long a time in the company of Christ Himself, and was entrusted with the money of the poor, so that his passion might be soothed thereby (for he was a thief) even then did not become any better, although he had been favoured with such great condescension. For since Christ knew that he was covetous, and destined to perish on account of his love of money he not only did not demand punishment of him for this at that time, but with a view to softening down his passion he was entrusted with the money of the poor, that having some means of appeasing his greed he might be saved from falling into that appalling gulf of sin, checking the greater evil beforehand by a lesser one.
