From Homily LVI: The Homilies of St. John Chrysostom on the Gospel According to St. Matthew
"This," it is said, "is My beloved Son" (Matthew 17:5). Now if He is beloved, fear not. For no one gives up one whom he loves. Be not thou therefore confounded; though thou lovest Him beyond measure, thou lovest Him not as much as He that begat Him.
"In whom I am well pleased." For not because He begat Him only, doth He love Him, but because He is also equal to Him in all respects, and of one mind with Him. So that the charm of love is twofold, or rather even threefold, because He is the Son, because He is beloved, because in Him He is well pleased.
But what means, "In whom I am well pleased?" As though He had said, "In whom I am refreshed, in whom I take delight;" because He is in all respects perfectly equal with Himself, and there is but one will in Him and in the Father, and though He continue a Son, He is in all respects one with the Father.
"Hear ye Him." So that although He choose to be crucified, you are not to oppose Him.
"And when they heard it, they fell on their face, and were sore afraid. And Jesus came and touched them, and said, Arise, and be not afraid. And when they lifted up their eyes, they saw no man, save Jesus only."
How was it that, when they heard these words, they were dismayed? And yet before this also a like voice was uttered at Jordan, and a multitude was present, and no one felt anything of the kind; and afterwards again, when also they said, "It thundered," yet neither at that time did they experience anything like this. How then did they fall down in the mount? Because there was solitude, and height. and great quietness, and a transfiguration full of awe, and a pure light, and a cloud stretched out; all which things put them in great alarm. And the amazement came thick on every side, and they fell down both in fear at once and in adoration.
But that the fear abiding so long might not drive out their recollection, presently He puts an end to their alarm, and is seen Himself alone, and commands them to tell no man this, until He is risen from the dead.
For "as they came down from the mount, He charged them to tell the vision to no man, until He were risen from the dead." For the greater the things spoken of Him, the harder to be received by the generality at that time; and the offense also from the cross was the more increased thereby.
Therefore He bids them hold their peace; and not merely so, but He again reminds them of the passion, and all but tells them also the cause, for which indeed He requires them to keep silence. For He did not, you see, command them never to tell any man, but "until He were risen from the dead." And saying nothing of the painful part, He expresses the good only.
What then? Would they not afterwards be offended? By no means. For the point required was the time before the crucifixion. Since afterwards they both had the spirit vouchsafed them, and the voice that proceeded from the miracles pleading with them, and whatsoever they said was thenceforth easy to be received, the course of events proclaiming His might more clearly than a trumpet, and no offense of that sort interrupting what they were about.
Nothing then is more blessed than the apostles, and especially the three, who even in the cloud were counted worthy to be under the same roof with the Lord.
But if we will, we also shall behold Christ, not as they then on the mount, but in far greater brightness. For not thus shall He come hereafter. For whereas then, to spare His disciples, He discovered so much only of His brightness as they were able to bear; hereafter He shall come in the very glory of the Father, not with Moses and Elias only, but with the infinite host of the angels, with the archangels, with the cherubim, with those infinite tribes, not having a cloud over His head, but even heaven itself being folded up.

Troparion of the holy Youths - Tone 4
O miracle of faith! The seven holy youths remained in a cave as though in a royal palace and died without corruption. After many years they rose up from sleep to convince all men of the Resurrection. Through their prayers, O Christ our God, have mercy on us all.
Kontakion of the holy Youths - Tone 4
They forsook the things of the world as corrupt; they received the gifts of incorruption and remained in death without corruption. They arose after many years having buried their enemies' unbelief. Today as we praise these seven holy youths let us give glory to Christ.
