Bede the Venerable ca. 673-735
They were not forbidden to listen to Moses and Elias, that is, the Law and the Prophets, but listening to the Son was to take precedence, since He came to fulfill the Law and the Prophets. It is impressed upon them that the light of Gospel truth was to be put before all the types and obscure signs of the Old Testament. (Homily 1.24, 242)
