leo1On Matthew 17:1-9 (the mystery of the Transfiguration)

A bright cloud overshadowed them, and behold a voice out of the cloud, saying, “This is My beloved Son, in whom I am well pleased; hear ye Him.”

[…]  “This is My Son,” Who sought not by grasping, and seized not in greediness, that equality with Me which He has, but remaining in the form of My glory, that He might carry out Our common plan for the restoration of mankind, He lowered the unchangeable Godhead even to the form of a slave.

“Hear ye Him,” therefore, unhesitatingly, in Whom I am throughout well pleased, and by Whose preaching I am manifested, by Whose humiliation I am glorified; because He is “the Truth and the Life,” He is My “Power and Wisdom.”

“Hear ye Him,” Whom the mysteries of the Law have foretold, Whom the mouths of prophets have sung.

“Hear ye Him,” Who redeems the world by His blood, Who binds the devil, and carries off his chattels, Who destroys the bond of sin, and the compact of the transgression.

Hear ye Him, Who opens the way to heaven, and by the punishment of the Cross prepares for you the steps of ascent to the Kingdom?

Why tremble ye at being redeemed? Why fear ye to be healed of your wounds?  Let that happen which Christ wills and I will.  Cast away all fleshly fear, and arm yourselves with faithful constancy; for it is unworthy that ye should fear in the Saviour’s Passion what by His good gift ye shall not have to fear even at your own end.

These things, dearly-beloved, were said not for their profit only, who heard them with their own ears, but in these three Apostles the whole Church has learnt all that their eyes saw and their ears heard.

Let all men’s faith then be established, according to the preaching of the most holy Gospel, and let no one be ashamed of Christ’s Cross, through which the world was redeemed.

And let not any one fear to suffer for righteousness’ sake, or doubt of the fulfilment of the promises, for this reason, that through toil we pass to rest and through death to life.

For all the weakness of our humility was assumed by Him, in Whom, if we abide in the acknowledgment and love of Him, we conquer as He conquered, and receive what he promised, because, whether to the performance of His commands or to the endurance of adversities, the Father’s fore-announcing voice should always be sounding in our ears, saying, “This is My beloved Son, in Whom I am well pleased; hear ye Him.”
