Luke 9:33

The dispensation was still at its beginning and not yet fulfilled. How would it have been fitting for Christ to abandon his love for the world and depart from his purpose of suffering on its behalf? By undergoing death in the flesh and by abolishing death by the resurrection from the dead, he redeemed all under heaven. Peter therefore knew not what he said.

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. 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?

(non occ.) 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.

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 labour; for it follows, Let us make three tabernacles, one for thee, &c.

And it came to pass, as they were departing. After the beginning of contemplation, he adds the progress of contemplation: in which two things are most especially required, namely surpassing joy over the gift bestowed and surpassing desire for its continuation, according to that passage …

And it happened, while they were departing from Him, that Peter said to Jesus: Master, it is good for us to be here, and let us make three tents, one for You, one for Moses, and one for Elijah, not knowing what he said. Oh, …

(Orat. de Trans. fig.) It were not good for thee, Peter, that Christ should abide there, for if He had remained, the promise made to thee would never receive its accomplishment. For neither wouldest thou 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 thou shalt enjoy the sight without ceasing, and dwell together with Him who is light and life. (ubi sup.) But the Lord ordained thee not the builder of tabernacles, but of the universal Church. Thy words have been brought to pass by thy disciples, by thy 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. (ubi sup.) 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.

And it came to pass, as they departed from him,....

The event described in these verses, commonly called "the transfiguration" — is one of the most remarkable events in the history of our Lord's earthly ministry. It is one of those passages which we should always read with particular thankfulness. It lifts a corner of the veil which hangs over the world to come — and throws light on some of the deepest truths of our religion. In the first place — this passage shows us something of the glory which Christ will have at His second coming.

The event described in these verses, commonly called "the transfiguration" — is one of the most remarkable events in the history of our Lord's earthly ministry. It is one of those passages which we should always read with particular thankfulness. It lifts a corner of the veil which hangs over the world to come — and throws light on some of the deepest truths of our religion. In the first place — this passage shows us something of the glory which Christ will have at His second coming. We read that, "As he was praying, the appearance of his face was altered, and his clothing became dazzling white!" — and that the disciples who were with Him "saw His glory." We need not doubt that this marvelous vision was meant to encourage and strengthen our Lord's disciples. They had just been hearing of His cross and death — and the self-denial and sufferings to which they must submit themselves, if they would be saved. They were now cheered by a glimpse of the "glory that would follow," and the reward which all faithful servants of their Master would one day receive. They had seen their Master's day of weakness. They now saw, for a few minutes — a pattern and specimen of His future power and glory. Let us take comfort in the thought, that there are good things laid up in store for all true Christians — which shall make ample amends for the afflictions of this present time. Now is the season for carrying the cross, and sharing in our Savior's humiliation. The crown, the kingdom, the glory — are all yet to come! Christ and His people are now, like David in the cave of Adullam — despised, and lightly esteemed by the world. There seems no form or loveliness in Him, or in His service. But the hour is coming, and will soon be here — when Christ shall take to Himself His great power and reign, and put down every enemy under His feet!

It is good for us to be here - Some MSS. add παντοτε, It is good for us to be Always here.
