These may help with understanding and reflecting, while Scripture remains an “inexhaustible treasury”…
St. Leo The Great:
[quote]The Holy Fathers well knew all this by practical experience, and they never cease to extol the sacred Scripture and its fruits. In innumerable passages of their writings we find them applying to it such phrases as "an inexhaustible treasury of heavenly doctrine,’’ or "an overflowing fountain of salvation,’’

110. What is the meaning of the Transfiguration?
Above all the Transfiguration shows forth the Trinity: “the Father in the voice, the Son in the man Jesus, the Spirit in the shining cloud” (Saint Thomas Aquinas). Speaking with Moses and Elijah about his “departure” (Luke 9:31), Jesus reveals that his glory comes by way of the cross and he anticipates his resurrection and his glorious coming “which will change our lowly body to be like his glorious body” (Philippians 3:21).
*“You were transfigured on the mountain and your disciples, as much as they were capable of it, beheld your glory, O Christ our God, so that when they should see you crucified they would understand that your passion was voluntary, and proclaim to the world that you truly are the splendor of the Father.” *(Byzantine Liturgy)
From a homily by St. Leo The Great:
***[FONT=Arial]The Law Through Moses…***Grace &Truth Through Jesus Christ[/FONT]
[FONT=Arial]This is an excerpt from a homily by St. Leo the Great - Pope (Sermo 51, 3-4, 8: PL 54, 310-311, 313) explaining the meaning of the Transfiguration of the Lord Jesus Christ on Mount Tabor. Saint Leo contrasts the law, symbolized by Moses, with the grace of the gospel brought by Jesus Christ.
St. Leo the Great was pope during the middle of the fifth century, a troubled time when barbarian armies were ravaging the once mighty Roman empire. He is perhaps most famous for persuading Attila the Hun to abandon his plans to sack the city of Rome. Leo, one of the Early Church Fathers, was such an extraordinary teacher that he is one of the few Popes of history to have been dubbed “the Great.”
[FONT=Arial]The Lord reveals his glory in the presence of chosen witnesses. His body is like that of the rest of mankind, but he makes it shine with such splendor that his face becomes like the sun in glory, and his garments as white as snow.
The great reason for this transfiguration was to remove the scandal of the cross from the hearts of his disciples, and to prevent the humiliation of his voluntary suffering from disturbing the faith of those who had witnessed the surpassing glory that lay concealed.
With no less forethought he was also providing a firm foundation for the hope of holy Church. The whole body of Christ was to understand the kind of transformation that it would receive as his gift. the members of that body were to look forward to a share in that glory which first blazed out in Christ their head.
The Lord had himself spoken of this when he foretold the splendor of his coming: Then the just will shine like the sun in the kingdom of their Father. Saint Paul the apostle bore witness to this same truth when he said: I consider that the sufferings of the present time are not to be compared to the future glory that is to be revealed in us. In another place he says: You are dead, and your life is hidden with Christ in God. When Christ, your life, is revealed, then you also will be revealed with him in glory.
This marvel of the transfiguration contains another lesson for the apostles, to strengthen them and lead them into the fullness of knowledge. Moses and Elijah, the law and the prophets, appeared with the Lord in conversation with him. This was in order to fulfil exactly, through the presence of these five men, the text which says: Before two or three witnesses every word is ratified. What word could be more firmly established, more securely based, than the word which is proclaimed by the trumpets of both old and new testaments, sounding in harmony, and by the utterances of ancient prophecy and the teaching of the Gospel, in full agreement with each other?
