Luke 9:36

While Christ is engaged in prayer, Peter is heavy with sleep, for he was weak, and did what was natural to man; as it is said, But Peter and they that were with him were heavy with sleep. But when they awake, they behold His glory, and the two men with Him; as it follows, And when they were awake, they saw his glory, and the two men that stood with him.

Or, by the word sleep, he means that strange maze that fell upon them by reason of the vision. For it was not night time, but the exceeding brightness of the light weighed down their weak eyes.

For the incomprehensible brightness of the Divine nature oppresses our bodily senses. For if the sight of the body is unable to contain the sun’s ray when opposite to the eyes which behold it, how can the corruption of our fleshly members endure the glory of God? And perhaps they were oppressed with sleep, that after their rest they might behold the sight of the resurrection. Therefore when they were awake they saw His glory. For no one, except he is watching, sees the glory of Christ. Peter was delighted, and as the allurements of this world enticed him not, was carried away by the glory of the resurrection. Hence it follows, And it came to pass as they departed, &c.

For perhaps holy Peter imagined that the kingdom of heaven was at hand, and therefore it seemed good to him to abide on the mount. DAMAS. It were not good for you, Peter, that Christ should abide there, for if He had remained, the promise made to you would never receive its accomplishment. For neither would you have obtained the keys of the kingdom, nor the tyranny of death been abolished. Seek not bliss before its time, as Adam did to be made a God. The time shall come when you shall enjoy the sight without ceasing, and dwell together with Him who is light and life.

But Peter distinguished not only by earnest feeling, but also by devout deeds, wishing like a zealous workman to build three tabernacles, offers the service of their united labor; for it follows, let us make three tabernacles, one for you, &c. DAMAS. But the Lord ordained you not the builder of tabernacles, but of the universal Church. Your words have been brought to pass by your disciples, by your sheep, in building a tabernacle, not only for Christ, but also for His servants. But Peter said not this deliberately, but through the inspiration of the Spirit revealing things to come, as it follows, not knowing what he said.

He knew not what he said, for neither was the time come for the end of the world, or for the Saints’ enjoyment of their promised hope. And when the dispensation was now commencing, how was it fitting that Christ should abandon His love of the world, Who was willing to suffer for it? DAMAS. It behoved Him also not to confine the fruit of His incarnation to the service of those only who were on the mount, but to extend it to all believers, which was to be accomplished by His cross and passion.

Peter also was ignorant what he said, seeing that it was not proper to make three tabernacles for the three. For the servants are not received with their Lord, the creature is not placed beside the Creator.

Nor does the condition of man in this corruptible body allow of making a tabernacle to God, whether in the soul or in the body, or in any other place; and although he knew not what he said, yet a service was offered which not by any deliberate forwardness, but its premature devotion, receives in abundance the fruits of piety. For his ignorance was part of his condition, his offer of devotion.

Or else Peter heard that it was necessary Christ must die, and on the third day rise again, but he saw around him a very remote and solitary place; he supposed therefore that the place had some great protection. For this reason he said, It is good for us to be here. Moses a too was present, who entered into the cloud. Elias, who on the mount brought down fire from heaven. The Evangelist then, to indicate the confusion of mind in which he utters this, added, Not knowing what he said.

Now in what Luke here says of Moses and Elias, And it came to pass as they departed from him, Peter said to Jesus, Master, it is good for us to be here, he must not be thought contrary to Matthew and Mark, who have so connected Peter’s suggestion of this, as if Moses and Elias were still speaking with our Lord. For they did not expressly state that Peter said it then, but rather were silent about what Luke added, that as they departed, Peter suggested this to our Lord.

But while Peter spoke, our Lord builds a tabernacle not made with hands, and enters into it with the Prophets. Hence it is added, While he thus spoke there came a cloud and overshadowed them, to show that He was not inferior to the Father. For as in the Old Testament it was said, the Lord dwelt in the cloud, so now also a cloud received our Lord, not a dark cloud, but bright and shining.

For the obscurity of the Law had passed away; for as smoke is caused by the fire, so the cloud by light; but because a cloud is the sign of calmness, the rest of the future state is signified by the covering of a cloud.

For it is the overshadowing of the divine Spirit which does not darken, but reveals secret things to the hearts of men.

Now His disciples being unable to bear this, fell down, humbled under the mighty hand of God, greatly tom afraid since they knew what was said to Moses, No man shall see my face, and live. Hence it follows, And they feared as they entered into the cloud.

Now observe, that the cloud was not black from the darkness of condensed air, and such as to overcast the sky with a horrible gloom, but a shining cloud, from which we were not moistened with rain, but as the voice of Almighty God came forth the dew of faith was shed upon the hearts of men. For it follows, And there came a voice out of the cloud, saying, This is my beloved Son: hear you him. Elias was not His Son. Moses was not. But this is the Son whom you see alone.

How then should men suppose Him who is really the Son to be made or created, when God the Father thundered c. from above, This is my beloved Son! as if He said, Not one of My sons, but He who is truly and by nature My Son, according to whose example the others are adopted. He ordered them then to obey Him, when He added, Hear you him. And to obey Him more than Moses and Elias, for Christ is the end of the Law and the Prophets. Hence the Evangelist adds significantly, And when the voice was past, Jesus was found alone.

Lest in truth any one should suppose that these words, This is my beloved Son, were uttered about Moses or Elias.

They then departed, when our Lord’s manifestation had begun. There are three seen at the beginning, one at the end; for faith being made perfect, they are one. Therefore are they also received into the body of Christ, because we also shall be one in Christ Jesus; or perhaps, because the Law and the Prophets came out from the Word.

Now those things which began from the Word, end in the Word. For by this he implies that up to a certain time the Law and the Prophets appear, as here Moses and Elias; but afterwards, at their departure, Jesus is alone. For now abides the Gospel, legal things having passed away.

And mark, that as when our Lord was baptized in Jordan, so also when He was glorified on the Mount, the mystery of the whole Trinity is declared, for His glory which we confess at baptism, we shall see at the resurrection. Nor in vain does the Holy Spirit appear here in the cloud, there in the form of a dove, seeing that he who now preserves with a simple heart the faith which he receives, shall then in the light of open vision look upon those things which he believed.

Now Jesus wishes not those things which relate to His glory to be spoken of before His passion. Hence it follows, And they kept it close. For men would have been offended, especially the multitude, if they saw Him crucified Who had been so glorified. DAMAS. This also our Lord commands, since He knew His disciples to be imperfect, seeing that they had not yet received the full measure of the Spirit, lest the hearts of others who had not seen should be prostrated by sorrow, and lest the traitor should be stirred up to a frantic hatred.

You ought to be very much ashamed of yourself on this account too, for permitting him to appear on the retired mountain in the company of Moses and Elias, whom he had come to destroy. This, to be sure, was what he wished to be understood as the meaning of that voice from heaven: “This is my beloved Son, hear Him”, Him , that is, not Moses or Elias any longer. The voice alone, therefore, was enough, without the display of Moses and Elias; for, by expressly mentioning whom they were to hear, he must have forbidden all others from being heard. …

Turning now to the law, which is properly ours, that is, to the Gospel, by what kind of examples are we met, until we come to definite dogmas? Behold, there immediately present themselves to us, on the threshold as it were, the two priestesses of Christian sanctity, Monogamy and Continence: one modest, in Zechariah the priest; one absolute, in John the forerunner: one appeasing God; one preaching Christ: one proclaiming a perfect priest; one exhibiting “more than a prophet,”, him, namely, who has not only preached or personally pointed out, but even baptized Christ. …

On the other hand, he whose “heart” was habitually found “lifted up” rather than fattened up, who in forty days and as many nights maintained a fast above the power of human nature, while spiritual faith subministered strength (to his body), both saw with his eyes God’s glory, and heard with his ears God’s voice, and understood with his heart God’s law: while He taught him even then (by experience) that man liveth not upon bread alone, but upon every word of God; in that the People, though fatter than he, could not constantly contemplate even Moses himself, fed as he had been upon God, nor his leanness, sated as it had been with His glory! Deservedly, therefore, even while in the flesh, did the Lord show Himself to him, the colleague of His own fasts, no less than to Elijah. …
