Thou then likewise, if you be willing to perform these things exactly, shall laugh all ills to scorn. Yea, for if you be but strengthened with such philosophy as is in these admonitions, nothing shall be able to hurt you. Since in what is he to harm you, who is minded to lay plots? Will he take away your money? Well, but before their threatening you were commanded to despise it, and to abstain from it so exceedingly, as not so much as even to ask any such thing of your Lord. But does he cast you into prison? Why, before your prison, you were enjoined so to live, as to be crucified even to all the world. But does he speak evil? Nay, from this pain also Christ has delivered you, by promising you without toil a great reward for the endurance of evil, and making you so clear from the anger and vexation hence arising, as even to command you to pray for them. But does he banish you and involve you in innumerable ills? Well, he is making the crown more glorious for you. But does he destroy and murder you? Even hereby he profits you very greatly, procuring for you the rewards of the martyrs, and conducting you more quickly into the untroubled haven, and affording you matter for a more abundant recompence, and contriving for you to make a gain of the universal penalty. Which thing indeed is most marvellous of all, that the plotters, so far from injuring at all, do rather make the objects of their despite more approved. To this what can be comparable? I mean, to the choice of such a mode of life as this, and no other, is.
Thus whereas He had called the way strait and narrow; to soothe our labors on this side also, He signifies the security thereof to be great, and great the pleasure; even as of the opposite course great is the unsoundness, and the detriment. For as virtue even from things here was signified by Him to have her rewards, so vice also her penalties. For what I am ever saying, that I will say now also: that in both ways He is everywhere bringing about the salvation of His hearers on the one hand by zeal for virtue, on the other by hatred of vice. Thus, because there would be some to admire what He said, while they yield no proof of it by their works, He by anticipation awakens their fears, saying, Though the things spoken be good, hearing is not sufficient for security, but there is need also of obedience in actions, and the whole lies chiefly in this. And here He ends His discourse, leaving the fear at its height in them.
For as with regard to virtue, not only from the things to come did He urge them (speaking of a kingdom, and of Heaven, and an unspeakable reward, and comfort, and the unnumbered good things): but also from the things present, indicating the firm and immoveable quality of the Rock; so also with respect to wickedness, not from the expected things only does He excite their fears (as from the tree that is cut down, and the unquenchable fire, and the not entering into the kingdom, and from His saying, “I know you not”): but also from the things present, the downfall, I mean, in what is said of the house.
4. Wherefore also He made His argument more expressive, by trying its force in a parable; for it was not the same thing to say, “The virtuous man shall be impregnable, but the wicked easily subdued,” as to suppose a rock, and a house, and rivers, and rain, and wind, and the like.
“And every one,” says He, “that hears these sayings of mine, and does them not, shall be likened to a foolish man, which built his house upon the sand.”
And well did He call this man “foolish”: for what can be more senseless than one building a house on the sand, and while he submits to the labor, depriving himself of the fruit and refreshment, and instead thereof undergoing punishment? For that they too, who follow after wickedness, do labor, is surely manifest to every one: since both the extortioner, and the adulterer, and the false accuser, toil and weary themselves much to bring their wickedness to effect; but so far from reaping any profit from these their labors, they rather undergo great loss. For Paul too intimated this when he said, “He that sows to his flesh, shall of his flesh reap corruption.” To this man are they like also, who build on the sand; as those that are given up to fornication, to wantonness, to drunkenness, to anger, to all the other things.
Such an one was Ahab, but not such Elijah (since when we have put virtue and vice along side of one another, we shall know more accurately the difference): for the one had built upon the rock, the other on the sand; wherefore though he were a king, he feared and trembled at the prophet, at him that had only his sheepskin. Such were the Jews but not the apostles; and so though they were few and in bonds, they exhibited the steadfastness of the rock; but those, many as they were, and in armor, the weakness of the sand. For so they said, “What shall we do to these men?” Do you see those in perplexity, not who are in the hands of others, and bound, but who are active in holding down and binding? And what can be more strange than this? Have you hold of the other, and art yet in utter perplexity? Yes, and very naturally. For inasmuch as they had built all on the sand, therefore also were they weaker than all. For this cause also they said again, “What do ye, seeking to bring this man's blood upon us?” What says he? Do you scourge, and are you in fear? Do you entreat despitefully, and art in dismay? Do you judge, and yet tremble? So feeble is wickedness.
But the Apostles not so, but how? “We cannot but speak the things which we have seen and heard.” Do you see a noble spirit? Do you see a rock laughing waves to scorn? Do you see a house unshaken? And what is yet more marvellous; so far from turning cowards themselves at the plots formed against them, they even took more courage, and cast the others into greater anxiety. For so he that smites adamant, is himself the one smitten; and he that kicks against the pricks, is himself the one pricked, the one on whom the severe wounds fall: and he who is forming plots against the virtuous, is himself the one in jeopardy. For wickedness becomes so much the weaker, the more it sets itself in array against virtue. And as he who wraps up fire in a garment, extinguishes not the flame, but consumes the garment; so he that is doing despite to virtuous men, and oppressing them, and binding them, makes them more glorious, but destroys himself. For the more ills you suffer, living righteously, the stronger are you become; since the more we honor self-restraint, the less we need anything; and the less we need anything, the stronger we grow, and the more above all. Such a one was John; wherefore him no man pained, but he caused pain to Herod; so he that had nothing prevailed against him that ruled; and he that wore a diadem, and purple, and endless pomp, trembles, and is in fear of him that is stripped of all, and not even when beheaded could he without fear see his head. For that even after his death he had the terror of him in full strength, hear what He says, “This is John, whom I slew.” Now the expression, “I slew,” is that of one not exulting, but soothing his own terror, and persuading his troubled soul to call to mind, that he himself slew him. So great is the force of virtue, that even after death it is more powerful than the living. For this same cause again, when he was living, they that possessed much wealth came unto him, and said, “What shall we do?” Is so much yours, and are you minded to learn the way of your prosperity from him that has nothing? The rich from the poor? The soldiers from him that has not even a house?
Such an one was Elias too: wherefore also with the same freedom did he discourse to the people. For as the former said, “You generation of vipers;” so this latter, “How long will you halt upon both your hips?” And the one said, “Have you killed, and inherited?” the other, “It is not lawful for you to have your brother Philip's wife.”
