Holy God, we praise Thy Name; Lord of all, we bow before Thee! All on earth Thy scepter claim, All in Heaven above adore Thee; Infinite Thy vast domain, Everlasting is Thy reign. Hark! the loud celestial hymn Angel choirs above are raising, Cherubim and seraphim, In unceasing chorus praising; Fill the heavens with sweet accord: Holy, holy, holy, Lord. Lo! the apostolic train Join the sacred Name to hallow; Prophets swell the loud refrain, And the white robed martyrs follow; And from morn to set of sun, Through the Church the song goes on. Holy Father, Holy Son, Holy Spirit, Three we name Thee; While in essence only One, Undivided God we claim Thee; And adoring bend the knee, While we own the mystery.
