O Peter, Shepherd good, our voices sing of thee; Thy very word had might from chains of sin to free; To thee, by power divine, the mystic keys were given, Which ope the skies to men, or close the gates of heaven. All honor, might, and power, and hymns of joy we bring, While to the Trinity eternal praise we sing: He rules the universe in wondrous Unity, And shall, throughout the days of all eternity.
