We read that this Lenten fast was formerly observed by Moses and Elijah, and by it is shown that the Gospel does not differ from the Law and the Prophets. Moreover, by this fast we are instructed that after Baptism we ought throughout the whole time of this present world to live soberly, fasting from vices and from friendship with the world. Furthermore, the Lord’s fast before His Passion signifies in Himself our
labor, while His refreshment after His Resurrection signifies in us consolation. Mystically, the Lord’s hunger signifies His desire for our salvation.
Just as the body lives by earthly food, so the soul lives by the word of God which proceeds from His mouth, when He wills to reveal to our frailty the counsel of His will through the sacred Scriptures. That he answered the devil by sentences of Scripture gave us an example of humility, so that whenever we suffer anything from wicked men we may be stirred more to instruction than to vengeance.
