3 Having first elevated their souls, and made them of a higher character, and having rendered them such as sorrow could not subdue, then He reproves their request.
But what can be this present saying? For indeed there are two points that are subjects of inquiry to many: one, if it be prepared for any to sit on His right hand; and then, if the Lord of all has not power to bestow it on them for whom it is prepared.
What then is the saying? If we solve the former point, then the second also will be clear to the inquirers. What then is this? No one shall sit on His right hand nor on His left. For that throne is inaccessible to all, I do not say to men only, and saints, and apostles, but even to angels, and archangels, and to all the powers that are on high.
At least Paul puts it as a peculiar privilege of the Only-Begotten, saying, “To which of the angels said He at any time, Sit on my right hand? And of the angels He says, who makes His angels spirits; but unto the Son, 'Your throne, O God.'”
How then says He, “To sit on my right hand and on my left is not mine to give,” as though there are some that should sit there? Not as though there are; far from it; but He makes answer to the thoughts of them who ask the favor, condescending to their understanding. For neither did they know that lofty throne, and His sitting at the right hand of the Father; how should they, when even the things that were much lower than these, and were daily instilled into them, they understood not? But they sought one thing only, to enjoy the first honors, and to stand before the rest, and that no one should stand before them with Him; even as I have already said before, that, since they heard of twelve thrones, in ignorance what the saying could mean, they asked for the first place.
What therefore Christ says is this: “You shall die indeed for me, and shall be slain for the sake of the gospel, and shall be partakers with me, as far as regards the passion: but this is not sufficient to secure you the enjoyment of the first seat, and to cause that you should occupy the first place. For if any one else should come, together with the martyrdom, possessed of all the other parts of virtue far more fully than you, not because I love you now, and prefer you to the rest, therefore shall I set aside him that is distinguished by his good works, and give the first honors to you.”
But thus indeed He did not say it, so as not to pain them, but darkly He intimates the self-same thing, saying, “You shall drink indeed of my cup, and you shall be baptized with the baptism that I am baptized with; but to sit on my right hand and on my left, this is not mine to give, but it shall be given to those for whom it is prepared.”
But for whom is it prepared? For them who could become distinguished by their works. Therefore He said not, It is not mine to give, but my Father's, lest any should say that He was too weak, or wanting in vigor for their recompense; but how? It is not mine, but of those for whom it is prepared.
And in order that what I say may be more plain, let us work it on an illustration, and let us suppose there was some master of the games, then that many excellent combatants went down to the contest, and that some two of the combatants that were most nearly connected with the master of the games were to come to him and say, “Cause us to be crowned and proclaimed,” confiding in their good-will and friendship with him; and that he were to say to them, “This is not mine to give, but it shall be given to them for whom it is prepared, by their labors, and their toils;” should we indeed condemn him as powerless? By no means, but we should approve him for his justice, and for having no respect of persons. Like then as we should not say that he did not give the crown from want of vigor, but as not wishing to corrupt the law of the games, nor to disturb the order of justice; in like manner now should I say Christ said this, from every motive to compel them, after the grace of God, to set their hopes of salvation and approval on the proof of their own good works.
Therefore He says, “For whom it is prepared.” For what, says He, if others should appear better than you? What, if they should do greater things? For shall you, because you have become my disciples, therefore enjoy the first honors, if you yourselves should not appear worthy of the choice?
For that He Himself has power over the whole, is manifest from His having the entire judgment. For to Peter too He speaks thus, “I will give you the keys of the Heavens.” And Paul also makes this clear where he says, “Henceforth is laid up for me the crown of righteousness, which the Lord, the righteous judge, will give me in that day; and not to me only, but unto all them also which have loved His appearing.” But the appearing was of Christ. But that no one will stand before Paul, is surely clear to every one.
And if He has expressed these things somewhat obscurely, marvel not. For to lead them on by hidden instruction, not to be rudely pressing Him without object or cause for the first honors (for from a human passion they felt this), and not wishing to give them pain, by the obscurity He effects both these objects.
“Then were the ten moved with indignation with respect to the two.” Then. When.? When He had reproved them. So long as the judgment was Christ's, they were not moved with indignation; but seeing them preferred, they were contented, and held their peace, out of reverence and honor to their Master.
And if they were vexed in mind, yet they dared not utter this. And when they had some feeling of human weakness towards Peter, at the time that He gave the didrachmas, they did not give way to anger, but asked only, “Who then is greatest?” But since here the request was the disciples', they are moved with indignation. And not even here are they straightway moved with indignation, when they asked, but when Christ had reproved them, and had said they should not enjoy the first honors, unless they showed themselves worthy of these.
