Luke 6:42

The Lord added to what had gone before a very necessary parable, as it is said, And he spoke a parable to them, for His disciples were the future teachers of the world, and it therefore became them to know the way of a virtuous life, having their minds illuminated as it were by a divine brightness, that they should not be blind leaders of the blind. And then he adds, Can the blind lead the blind? But if any should chance to attain to an equal degree of virtue with their teachers, let them stand in the measure of their teachers, and follow their footsteps. Hence it follows, The disciple is not above his master. Hence also Paul says, Be you also followers of me, as I am of Christ. Since Christ therefore judged not, why judge you? for He came not to judge the world, but to show mercy.

Or else, If you judge another, and in the very same way sin yourself, are not you like to the blind leading the blind? For how can you lead him to good when you also yourself commit sin? For the disciple is not above his master. If therefore you sin, who think yourself a master and guide, where will he be who is taught and led by you? For he will be the perfect disciple who is as his master.

Or the sense of this sentence depends upon the former, in which we are enjoined to give alms, and forgive injuries. If, says He, anger has blinded you against the violent, and avarice against the grasping, how can you with your corrupt heart cure his corruption? If even your Master Christ, who as God might revenge His injuries, chose rather by patience to render His persecutors more merciful, it is surely binding on His disciples, who are but men, to follow the same rule of perfection.

Or, He has added the words, Can the blind, lead the blind, in order that they, might not expect to receive from the Levites that measure of which He says, They shall give into your bosom, because they gave tithes to them. And these He calls blind, because they received not the Gospel, that the people might the rather now begin to hope for that reward through the disciples of the Lord, whom wishing to point out as His imitators, He added, The disciple is not above his master.

But the Lord introduces another parable taken from the same figure, as follows, but why see you the mote (that is, the slight fault) which is in your brother’s eye, but the beam which is in your own eye (that is, your great sin) you regard not?

Now this has reference to the previous parable, in which He forewarned them that the blind cannot be led by the blind, that is, the sinner corrected by the sinner. Hence it is said, Or, how can you say to your brother, Brother let me cast out the mote that is in your eye, if you see not the beam that is in your own eye?

As if He said, How can he who is guilty of grievous sins, (which He calls the beam,) condemn him who has sinned only slightly, or even in some cases not at all? For this the mote signifies.

But these words are applicable to all, and especially to teachers, who while they punish the least sins of those who are put under them, leave their own unpunished. Wherefore the Lord calls them hypocrites, because to this end judge they the sins of others, that they themselves might seem just. Hence it follows, You hypocrite, first cast the beam out of your own eye, &c.

That is to say, first show yourself clean from great sins, and then afterwards shall you give counsel to your neighbor, who is guilty only of slight sins.

In truth, self knowledge seems the most important of all. For not only the eye, looking at outward things, fails to exercise its sight upon itself, but our understanding also, though very quick in apprehending the sin of another, is slow to perceive its own defects.

7. But since we quoted the language of Paul regarding Christ, where He says of Him that He is “the brightness of the glory of God, and the express figure of His person,” let us see what idea we are to form of this. According to John, “God is light.” The only-begotten Son, therefore, is the glory of this light, proceeding inseparably from (God) Himself, as brightness does from light, and illuminating the whole of creation. For, agreeably to what we have already explained as to the manner in which He is the Way, and conducts to the Father; and in which He is the Word, interpreting the secrets of wisdom, and the mysteries of knowledge, making them known to the rational creation; and is also the Truth, and the Life, and the Resurrection, in the same way ought we to understand also the meaning of His being the brightness: for it is by its splendour that we understand and feel what light itsel …

Since the great body of (the heretics) do not employ the counsel of the Lord, by having the beam in the eye, and announce that they see when in reality labouring under blindness, it seems to us expedient in no wise to be silent concerning the tenets of these. Our object is, that by the refutation accomplished by us, the (heretics), being of themselves ashamed, may be brought to know how the Saviour has advised (men) first to take away the beam, then to behold clearly the mote that is in thy brother’s eye. Having therefore adequately and sufficiently explained the doctrines of the majority (of the heretics) in the seven books before this, we shall not now be silent as regards the (heterodox) opinions that follow (from these). …

2. That I may not make myself tedious or exceed the due limits of a letter by repeating old stories, I will briefly relate to you an incident which happened in my childhood. The saintly Athanasius bishop of Alexandria had summoned the blessed Antony to that city to confute the heretics there. Hereupon Didymus, a man of great learning who had lost his eyes, came to visit the hermit and, the conversation turning upon the holy scriptures, Antony could not help admiring his ability and eulogizing his insight. At last he said: You do not regret, do you, the loss of your eyes? At first Didymus was ashamed to answer, but when the question had been repeated a second time and a third, he frankly confessed that his blindness was a great grief to him. …
