Agnus Dei is the Latin name under which the "Lamb of God" is honoured within Christian liturgies descending from the historic Latin liturgical tradition, including those of Roman Catholicism, Lutheranism and Anglicanism. It is the name given to a specific prayer that occurs in these liturgies, and is the name given to the music pieces that accompany the text of this prayer. The use of the title "Lamb of God" in liturgy is based on John 1:29, in which St. John the Baptist, upon seeing Jesus, proclaims "Behold, the Lamb of God, who takes away the sin of the world!" Liturgical usage.
