Why Did Moses and Elijah Appear on the Mountain? - Teaching and Messages
2 While they watched, Jesus' appearance was changed; his face became bright like the sun, and his clothes became white as light. 3 Then Moses and Elijah. It goes like this: Moses and Elijah came close to seeing God's face in their own day (close encounters with the divine Holiness), but could not. Apostle Luke says that Moses and Elijah appeared along with Jesus Christ “with “For the living know that they will die, but the dead know nothing at all, nor do.
Why Did Moses and Elijah Appear on the Mountain?
One was the great representative of the Law, which was a "school master" or "servant-tutor" see Note on Galatians 3: Of one it had been said that a "Prophet like unto him" should come in the latter days Deuteronomy The close of the ministry of each was not after the "common death of all men.
Both were associated in men's minds with the glory of the kingdom of the Christ.
Another Jewish tradition predicts his appearance with that of Elijah. Their presence now was an attestation that their work was over, and that the Christ had come. It is significant that the word for "decease" exodos reappears in this sense once only in the New Testament, and then in close connection with a reference to the Transfiguration 2Peter 1: Pulpit Commentary Verse 3.

The exclamation, thrice repeated ver. They who now appeared were no delusive, imaginary figures, but real personages, objectively presented to the spectators, in such bodies as appertained to their condition.
Luke adds, "who appeared in glory," radiant with the light which always accompanies heavenly visitors. Why these two saints were chosen to be present on this momentous occasion may be explained by various considerations. Both these worthies experienced something unparalleled in their departure from this life. Elijah was taken up to heaven without dying; Moses died, indeed, but he was buried by God in an unknown grave, and his body was under the especial care of Michael the archangel see Jude 1: From the unseen world these were brought to do homage to the Messiah - Moses, a type of those blessed spirits who in Paradise await the final consummation, Elijah, a type of the saints who, after the resurrection, perfect in soul and body, shall enter into glory.
Here were the representatives of the Law and the prophets, the principal supporters of the old covenant, honouring him who was introducing the new covenant, which was to fulfil and supersede the previous one.
Spurious, degraded Judaism rejected Christ's claims; real, orthodox Judaism acknowledged him and reverenced him as the Christ foretold and fort, shadowed, "of whom Moses and the prophets did write" John 1: Now, too, it was made manifest that Jesus was not Elias or one of the prophets, as some erroneously had supposed, but different from and superior to all; that he had power over life and death, and could bring whom he would from the unseen World; that the cross and Passion were not degrading, or proofs of weakness, but glorious and triumphant accomplishments of the will or God.
Transfiguration of Jesus
The question is asked - How did Peter and the rest recognize the two heavenly visitants? There may have been something conventional in their garb or appearance, which at once identified them; or the apostles may have known them by spiritual intuition or special revelation; or they may have gathered their knowledge from the conversation which they overheard.
Anyhow, it was necessary that the two should be recognized, otherwise their appearance would have lost its significance, and the confirmation which they were intended to afford would fail to be given.
Is there here an intimation that in heaven the blessed will know each other, though they never met in the flesh - shall know even as they have been known? Although Moses had died and Elijah had been taken up to heaven centuries before as in 2 Kings 2: In the 2nd century, Saint Irenaeus was fascinated by the Transfiguration and wrote: In the same vein, building on 2 Corinthians 3: Unlike Catholic saints such as Padre Pio or Francis who considered stigmata a sign of the imitation of Christ Eastern Orthodox saints have never reported stigmatabut saints such as Seraphim and Silouan have reported being transfigured by an inward light of grace.
Between the 6th and 9th centuries the iconography of the transfiguration in the East influenced the iconography of the resurrection, at times depicting various figures standing next to a glorified Christ. Origen was the first to comment that the presence of Moses and Elijah represented the "Law and the Prophets", referring to the Torah also called the Pentateuch and the rest of the Hebrew Bible.God talk to Moses
Several commentators have noted that Jesus describes the transfiguration using the Greek word orama Matthew Mount Tabor is traditionally identified as the Mount of Transfiguration.

See  citing Origen 's reference to Ps France notes that Mount Hermon is closest to Caesarea Philippimentioned in the previous chapter of Matthew.
