Êxodo 34

Êxodo 34:28

The forty-day fast of Lent draws its authority from the Old Testament, from the fasts of Moses and Elijah, and from the gospel, because the Lord fasted that many days, showing that the gospel is not at variance with the Law and the Prophets. The Law is personified by Moses, the Prophets by Elijah, between whom the Lord appeared transfigured on the mountain. — LETTER 55
