Te Deum

The Te Deum (also known as Ambrosian Hymn or A Song of the Church) is an early Christian hymn of praise. The title is taken from its opening Latin words, Te Deum laudamus, rendered as "Thee, O God, we praise".

The hymn remains in regular use in the Catholic Church in the Office of Readings found in the Liturgy of the Hours, and in thanksgiving to God for a special blessing such as the election of a pope, the consecration of a bishop, the canonization of a saint, a religious profession, the publication of a treaty of peace, a royal coronation, etc. It is sung either after Mass or the Divine Office or as a separate religious ceremony. The hymn also remains in use in the Anglican Communion and some Lutheran Churches in similar settings.
