Dear friends, why does the fact that God has taught us such a prayer as this astonish us? Did he not express all of our prayers in his own words of life? Indeed this was already foretold by Isaiah. Filled with the Holy Spirit, he spoke of the majesty and fidelity of God: The Lord will speak a final brief word of justice, a word throughout the world. Our Lord Jesus Christ came for all mankind. He gathered together male and female, the learned and the unlearned, the old and the young and taught them his saving doctrine. He did not want his disciples to be burdened by memorizing his teaching; he made a complete summary of his commands such as was necessary for a trusting faith, and could be quickly learned.
