Matthew 6:23

Having spoken of the bringing the understanding into captivity because it was not easy to be understood of many, He transfers it to a sensible instance, saying, "The light of thy body is thy eye." As though He had said, If you do not know what is meant by the loss of the understanding, learn a parable of the bodily members; for what the eye is to the body, that the understanding is to the soul. As by the loss of the eyes we lose much of the use of the other limbs, so when the understanding is corrupted, your life is filled with many evils.

That is an illustration drawn from the senses. As the whole body is in darkness, where the eye is not single, so if the soul has lost her original brightness, every sense, or that whole part of the soul to which sensation belongs, will abide in darkness. Wherefore He says, "If then the light which is in thee be darkness, how great is that darkness!" that is, if the senses which are the soul's light be darkened by vice, in how great darkness do you suppose the darkness itself will be wrapped?

It seems that He is not here speaking of the bodily eye, or of the outward body that is seen, or He would have said, If thine eye be sound, or weak; but He says, "single," and, "evil." But if one have a benign yet diseased eye, is his body therefore in light? Or if an evil yet a sound, is his body therefore in darkness?

Those who have thick eye-sight see the lights multiplied; but the single and clear eye sees them single and clear.

Or; The eye He speaks of is not the external but the internal eye. The light is the understanding, through which the soul sees God. He whose heart is turned to God, has an eye full of light; that is, his understanding is pure, not distorted by the influence of worldly lusts. The darkness in us is our bodily senses, which always desire the things that pertain to darkness. Whoso then has a pure eye, that is, a spiritual understanding, preserves his body in light, that is, without sin; for though the flesh desires evil, yet by the might of divine fear the soul resists it. But whoever has an eye, that is, an understanding, either darkened by the influence of the malignant passions, or fouled by evil lusts, possesses his body in darkness; he does not resist the flesh when it lusts after evil things, because he has no hope in Heaven, which hope alone gives us the strength to resist desire.

Otherwise; from the office of the light of the eye, He calls it the light of the heart; which if it continue single and brilliant, will confer on the body the brightness of the eternal light, and pour again into the corrupted flesh the splendor of its origin, that is, in the resurrection. But if it be obscured by sin, and evil in will, the bodily nature will yet abide subject to all the evils of the understanding.

Otherwise; by the eye here we may understand our purpose; if that be pure and right, all our works which we work according thereto are good. These He here calls the body, as the Apostle speaks of certain works as members; "Mortify your members, fornication and uncleanness." [Col 3:5] We should look then, not to what a person does, but with what mind he does it. For this is the light within us, because by this we see that we do with good intention what we do. "For all which doth make manifest is light." [Eph 5:13] But the deeds themselves, which go forth to men's society, have a result to us uncertain, and therefore He calls them darkness; as when I give money to one in need, I know not what he will do with it. If then the purport of your heart, which you can know, is defiled with the lust of temporal things, much more is the act itself, of which the issue is uncertain, defiled. For even though one should reap good of what you do with a purport not good, it will be imputed to you as you did it, not as it resulted to him. If however our works are done with a single purport, that is with the aim of charity, then are they pure and pleasing in God's sight.

But acts which are known to be in themselves sins, are not to be done as with a good purpose; but such works only as are either good or bad, according as the motives from which they are done are either good or bad, and are not in themselves sins; as to give food to the poor is good if it be done from merciful motives, but evil if it be done from ostentation. But such works as are in themselves sins, who will say that they are to be done with good motives, or that they are not sins? Who would say, Let us rob the rich, that we may have to give to the poor?

Otherwise; if the light that "is in thee," that is, if what we have begun to do well, we overcloud with evil purpose, when we do things which we know to be in themselves evil, "how great is the darkness!"

ap. Gloss. ord.: Otherwise; faith is likened to a light, because by it the goings of the inner man, that is, action, are lightened, that he should not stumble according to that, "Thy word is a light to my feet." [Ps 119:105] If that then be pure and single, the whole body is light; but if defiled, the whole body will be dark. Yet otherwise; by the light may be understood the ruler of the Church, who may be well called the eye, as he it is that ought to see that wholesome things be provided for the people under him, which are understood by the body. If then the ruler of the Church err, how much more will the people subject to him err?

As Celsus supposes that we uphold the doctrine of the resurrection in order that we may see and know God, he thus follows out his notions on the subject: “After they have been utterly refuted and vanquished, they still, as if regardless of all objections, come back again to the same question, ‘How then shall we see and know God? how shall we go to Him?’” Let any, however, who are disposed to hear us observe, that if we have need of a body for other purposes, as for occupying a material locality to which this body must be adapted, and if on that account the “tabernacle” is clothed in the way we have shown, we have no need of a body in order to know God. For that which sees God is not the eye of the body; it is the mind which is made in the image of the Creator, and which God has in His providence rendered capable of that knowledge. …

Do ye not shudder when ye hear all this? Let us see now, whether there be not things more grievous than these in the case of the covetous. For these too, in the first place, have a severer jailor, viz. avarice, and so much severer, as that besides their body he chains also their soul. And this darkness also is more awful than that. For it is not subject to sense, but they producing it within, whithersoever they go, carry it about with themselves. For the eye of their soul is put out: which is the reason why more than all Christ calls them wretched, saying, “But if the light that is in thee be darkness, how great is that darkness.” (S. Matt.vi. 23 .) And they for their part have at least a lamp shining, but these are deprived even of this beam of light; and therefore every day they fall into countless pitfalls. …

It was not then by his miracles that men were made believers; no, it was not the miracles that did this, nor was it upon the ground of these that he claimed his high pretension, but upon those other grounds. For a man must be alike irreproachable in conduct, prudent and discreet in his dealings with others, regardless of danger, and apt to teach. It was by these qualifications that the greater part of his success was achieved. Where there were these, there was no need of miracles. At least we see he was successful in numberless such cases, quite antecedently to the use of miracles. But, now-a-days, we without any of these would fain command all things. Yet if one of them be separated from the other, it henceforth becomes useless. What is the advantage of a man’s being ever so regardless of danger, if his life be open to censure. …

Why does he bring forward such an one? To stop the mouths of those heretics, who condemned marriage, showing that it is not an unholy thing in itself, but so far honorable, that a married man might ascend the holy throne; and at the same reproving the wanton, and not permitting their admission into this high office who contracted a second marriage. For he who retains no kind regard for her who is departed, how shall he be a good president? and what accusation would he not incur? For you all know, that though it is not forbidden by the laws to enter into a second marriage, yet it is a thing liable to many ill constructions. Wishing therefore a ruler to give no handle for reproach to those under his rule, he on this account says, “If any be blameless,” that is, if his life be free from reproach, if he has given occasion to no one to assail his character. …

5. L. Pray, have you not read what is said concerning the bishops,“Ye are the salt of the earth: but if the salt have lost its savour, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out and trodden under foot of man.” And then there is the fact that the priest intercedes with God for the sinful people, while there is no one to entreat for the priest. Now these two passages of Scripture tend to the same conclusion. For as salt seasons all food and nothing is so pleasant as to please the palate without it: so the bishop is the seasoning of the whole world and of his own Church, and if he lose his savour through the denial of truth, or through heresy, or lust, or, to comprehend all in one word, through sin of any kind, by what other can he be seasoned, when he was the seasoning of all? The priest, we know, offers his oblation for the layman, lays his hand u …

6. The questions for you to answer were arranged, as I shall presently show, under eight heads. You touch only three, and pass on. As regards the rest, you maintain a magnificent silence. If you had with perfect frankness replied to seven, I should still cling to the charge which remained; and what you said nothing about, that I should hold to be the truth. But as things are, you have caught the wolf by the ears; you can neither hold fast, nor dare let go. With a sort of careless security and an air of abstraction, you skim over and touch the surface of three in which there is nothing or but little of importance. And your procedure is so dark and close that you confess more by your silence than you rebut by your arguments. …
