Te Deum Laudamus (with lyrics and translation)

This is the Catholic Church's most famous hymn of thanksgiving. It is similar in meaning to the Gloria in Excelsis Deo, only it is much more elaborate and solemn.

Authorship of the hymn is traditionally ascribed to Saint Ambrose (died 397) or Saint Augustine (died 430). In 19th-century scholarship, Saint Hilary of Poitiers (died 367) and Saint Nicetas of Remesiana (died 414) were proposed as possible authors.

The petitions at the end of the hymn (beginning Salvum fac populum tuum) are a selection of verses from the book of Psalms, appended subsequently to the original hymn.

The hymn follows the outline of the Apostles' Creed, mixing a poetic vision of the heavenly liturgy with its declaration of faith. Calling on the name of God immediately, the hymn proceeds to name all those who praise and venerate God, from the hierarchy of heavenly creatures to those Christian faithful already in heaven to the Church spread throughout the world.

The hymn then returns to its credal formula, naming Christ and recalling his birth, suffering and death, his resurrection and glorification. At this point the hymn turns to the subjects declaiming the praise, both the universal Church and the singer in particular, asking for mercy on past sins, protection from future sin, and the hoped-for reunification with the elect
