And there appeared unto them Elijah with Moses: and they were talking with Jesus.
Read Chapter 9
Bede
AD 735
Moses and Elijah, who talked with the Lord on the mountain, and spoke about his passion and resurrection, represent the oracles of the law and prophets which were fulfilled in the Lord…. The figures of Moses and Elijah embrace all who are finally to reign with the Lord. By Moses, who died and was buried, we can understand those who at the judgment are going to be raised up from death. By Elijah, on the other hand, who has not yet paid the debt of death, we understand those who are going to be found alive in the flesh at the judge’s coming.
For both the one and the other had courageously withstood a tyrant: one the Egyptian, the other Ahab; and this on behalf of a people who were both ungrateful and disobedient…. And both were simple unlearned men. One was slow of speech and weak of voice. The other a rough countryman. And both were men who had despised the riches of this world. For Moses possessed nothing. And Elijah had nothing but his sheepskin. Gospel of St. Matthew, Homily
Since, therefore, He reserves to some future time His presence and speech face to face with Moses-a promise which was afterwards fulfilled in the retirement of the mount (of transfiguration), when as we read in the Gospel "Moses appeared talking with Jesus"
