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.

—Te Deum, c. 4th century.
