Agnus Dei



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, in which St. John the Baptist, upon seeing Jesus, proclaims "Behold, the Lamb of God, who takes away the sin of the world!"



Latin Catholic
The Syrian custom of a chant addressed to the Lamb of God was introduced into the Roman Rite Mass by Pope Sergius I (687–701) in the context of his rejection of the Council of Trullo of 692 (which was well received in the Byzantine East), whose canons had forbidden the iconographic depiction of Christ as a lamb instead of a man.

The verse used in the first and second invocations may be repeated as many times as necessary whilst the celebrant prepares the host and wine for communion.

In a Tridentine Requiem Mass, the words "miserere nobis" are replaced by "dona eis requiem" (grant them rest), while "dona nobis pacem" is replaced by "dona eis requiem sempiternam" (grant them eternal rest). Virtually every Mass setting includes an Agnus Dei

The priest uses the phrase "Lamb of God" again, later in the Mass. While displaying the Eucharistic species to the people before giving them Holy Communion, he says: "Ecce Agnus Dei, ecce qui tollit peccata mundi. Beati qui ad cenam Agni vocati sunt." ("Behold the Lamb of God, behold Him who takes away the sins of the world. Blessed are those called to the supper of the Lamb.")
