Patristic Wisdom: Looking to the Transfiguration

Now it came to pass, about eight days after these sayings, that He took Peter, John, and James and went up on the mountain to pray. As He prayed, the appearance of His face was altered, and His robe became white and glistening. And behold, two men talked with Him, who were Moses and Elijah, who appeared in glory and spoke of His decease which He was about to accomplish at Jerusalem. But Peter and those with him were heavy with sleep; and when they were fully awake, they saw His glory and the two men who stood with Him. Then it happened, as they were parting from Him, that Peter said to Jesus, “Master, it is good for us to be here; and let us make three tabernacles: one for You, one for Moses, and one for Elijah”—not knowing what he said. While he was saying this, a cloud came and overshadowed them; and they were fearful as they entered the cloud. And a voice came out of the cloud, saying, “This is My beloved Son. Hear Him!” When the voice had ceased, Jesus was found alone. But they kept quiet, and told no one in those days any of the things they had seen. (Luke 9:28–36)

The standing, therefore, of Moses and Elijah before Him, and their talking with one another, was a sort of representation, excellently displaying our Lord Jesus Christ, as having the law and the prophets for His body guard, as being the Lord of the law and the prophets, and as foreshown in them by those things which in mutual agreement they before proclaimed. For the words of the prophets are not at variance with the teachings of the law. And this I imagine was what Moses the most priestly and Elijah the most distinguished of the prophets were talking of with one another.…

Besides the wonderful and ineffable sight of Christ’s glory, something else was done, useful and necessary for the confirmation of their faith in Him: and not for the disciples only, but even for us too. For a voice was given forth from the cloud above, as from God the Father, saying: “This is My beloved Son, hear Him. And when there was the voice,” it says, “Jesus was found alone.” What then will he who is disputatious and disobedient, and whose heart is incurable, say to these things? Lo! Moses is there, and does the Father command the holy apostles to hear him? Had it been His will that they should follow the commandments of Moses, He would have said, I suppose, Obey Moses; keep the law. But this was not what God the Father here said, but in the presence of Moses and the prophets, He commands them rather to hear Him. And that the truth might not be subverted by any, affirming that the Father rather bade them hear Moses, and not Christ the Savior of us all, the Evangelist has clearly marked it, saying, “When there was the voice, Jesus was found alone.” When therefore God the Father, from the cloud overhead, commanded the holy apostles, saying, “Hear Him,” Moses was far away, and Elijah too was no longer near; but Christ was there alone. Him therefore He commanded them to obey.
