The Transfiguration of our Lord
‘And there appeared to them Moses and Elijah talking with him’. And the words that they said to him were such as these: they were thanking him that their words and those of all their fellow Prophets had been fulfilled by his coming. They offered him worship for the salvation which he had wrought for the human race; and that he had fulfilled in reality the mystery they had only sketched. There was joy for the Prophets and the Apostles by this ascent of the mountain. The Prophets rejoiced when they saw his humanity, which they had not known. The Apostles also rejoiced when they saw the glory of his divinity, which they had not known, and heard the voice of the Father bearing witness to his Son; and through this they recognized his incarnation, which was concealed from them. And the witness of the three was sealed by the Father’s voice and by Moses and Elijah, who stood by him like servants, and they looked to one another: the Prophets to the Apostles and the Apostles to the Prophets. There the authors of the old covenant saw the authors of the new. Holy Moses saw Simon the sanctified; the steward of the Father saw the administrator of the Son. The former divided the sea for the people to walk in the middle of the waves; the latter raised a tent for the building of the Church. The virgin of the old covenant saw the virgin of the new: Elijah and John; the one who mounted on the chariot of fire and the one who leaned on the breast of the flame. And the mountain became a type of the Church, and on it Jesus united the two covenants, which the Church received, and made known to us that he is the giver of the two. The one received his mysteries; the other revealed the glory of his works."
