St. Damasus was Supreme Pontiff from 366 to 384. He was a very learned man, well versed in the Scriptures. He commissioned St. Jerome to complete the translation of the Bible into the Latin language. Shortly after his reign the 72 books of the Bible, hitherto scattered in different parts of the Orient, were collected into one volume. He defended the rights of the Holy See, and beautified the Roman resting places of the Christian dead and of the saints. He also confirmed the practice of singing the Psalms day and night in the churches and adding a Glory Be at the end of each Psalm.
Grant, we pray, O Lord, that we may constantly exalt the merits of your Martyrs, whom Pope Saint Damasus so venerated and loved.
