Homilies on the Gospel of St. Matthew

³ On this account then He adds another argument, which I have already mentioned, saying,

“Where the man's treasure is, there is his heart also.”

For though none of these things should come to pass, says He, you will undergo no small harm, in being nailed to the things below, and in becoming a slave instead of a freeman, and casting yourself out of the heavenly things, and having no power to think on anything that is high, but all about money, usuries and loans, and gains, and ignoble traffickings. Than this what could be more wretched? For in truth such an one will be worse off than any slave, bringing upon himself a most grievous tyranny, and giving up the chiefest thing of all, even the nobleness and the liberty of man. For how much soever any one may discourse unto you, you will not be able to hear any of those things which concern you, while your mind is nailed down to money; but bound like a dog to a tomb, by the tyranny of riches, more grievously than by any chain, barking at all that come near you, you have this one employment continually, to keep for others what you have laid up. Than this what can be more wretched?

However, forasmuch as this was too high for the mind of His hearers, and neither was the mischief within easy view of the generality, nor the gain evident, but there was need of a spirit of more self-command to perceive either of these; first, He has put it after those other topics, which are obvious, saying, “Where the man's treasure is, there is his heart also;” and next He makes it clear again, by withdrawing His discourse from the intellectual to the sensible, and saying,

“The light of the body is the eye.”

What He says is like this: Bury not gold in the earth, nor do any other such thing, for thou dost but gather it for the moth, and the rust, and the thieves. And even if you should entirely escape these evils, yet the enslaving of your heart, the nailing it to all that is below, you will not escape: “For wheresoever your treasure may be, there is your heart also.” As then, laying up stores in heaven, you will reap not this fruit only, the attainment of the rewards for these things, but from this world you already receive your recompence, in getting into harbor there, in setting your affections on the things that are there, and caring for what is there (for where you have laid up your treasures, it is most clear you transfer your mind also); so if you do this upon earth, you will experience the contrary.

But if the saying be obscure to you, hear what comes next in order. “The light of the body is the eye; if therefore your eye be single, your whole body shall be full of light. But if your eye be evil, your whole body shall be full of darkness. But if the light that is in you be darkness, how great is the darkness!”

He leads His discourse to the things which are more within the reach of our senses. I mean, forasmuch as He had spoken of the mind as enslaved and brought into captivity, and there were not many who could easily discern this, He transfers the lesson to things outward, and lying before men's eyes, that by these the others also might reach their understanding. Thus, “If you know not,” says He, “what a thing it is to be injured in mind, learn it from the things of the body; for just what the eye is to the body, the same is the mind to the soul.” As therefore you would not choose to wear gold, and to be clad in silken garments, your eyes withal being put out, but accountest their sound health more desirable than all such superfluity (for, should you lose this health or waste it, all your life besides will do you no good): for just as when the eyes are blinded, most of the energy of the other members is gone, their light being quenched; so also when the mind is depraved, your life will be filled with countless evils: — as therefore in the body this is our aim, namely, to keep the eye sound, so also the mind in the soul. But if we mutilate this, which ought to give light to the rest, by what means are we to see clearly any more? For as he that destroys the fountain, dries up also the river, so he who has quenched the understanding has confounded all his doings in this life. Wherefore He says, “If the light that is in you be darkness, how great is the darkness?”

For when the pilot is drowned, and the candle is put out, and the general is taken prisoner; what sort of hope will there be, after that, for those that are under command?

Thus then, omitting now to speak of the plots to which wealth gives occasion, the strifes, the suits (these indeed He had signified above, when He said, “The adversary shall deliver you to the judge, and the judge to the officer”); and setting down what is more grievous than all these, as sure to occur, He so withdraws us from the wicked desire. For to inhabit the prison is not nearly so grievous, as for the mind to be enslaved by this disease; and the former is not sure to happen, but the other is connected as an immediate consequent with the desire of riches. And this is why He puts it after the first, as being a more grievous thing, and sure to happen.

For God, He says, gave us understanding, that we might chase away all ignorance, and have the right judgment of things, and that using this as a kind of weapon and light against all that is grievous or hurtful, we might remain in safety. But we betray the gift for the sake of things superfluous and useless.

For what is the use of soldiers arrayed in gold, when the general is dragged along a captive? What the profit of a ship beautifully equipped, when the pilot is sunk beneath the waves? What the advantage of a well-proportioned body, when the sight of the eyes is stricken out? As therefore, should any one cast into sickness the physician (who should be in good health, that he may end our diseases), and then bid him lie on a silver couch, and in a chamber of gold, this will nothing avail the sick persons; even so, if you corrupt the mind (which has power to put down our passions), although thou set it by a treasure, so far from doing it any good, you have inflicted the very greatest loss, and hast harmed your whole soul.
