Agnus Dei (liturgy) The Agnus Dei is part of nearly all settings by composers of sung masses. The priest again uses the phrase "Lamb of God", in a more complete quotation from , when displaying the consecrated Host (or the Host and Chalice) 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). Agnus Dei (liturgy) In the Mass of the Roman Rite
Agnus Dei (liturgy) the Roman Missal, § 83, states: "The supplication "Agnus Dei", is, as a rule, sung by the choir or cantor with the congregation responding; or it is, at least, recited aloud. This invocation accompanies the fraction and, for this reason, may be repeated as many times as necessary until the rite has reached its conclusion, the last time ending with the words "dona nobis pacem" ('grant us peace')." In Tridentine Requiem Masses, the first two invocations ended with "dona eis requiem" (give them rest) instead of "miserere nobis", and the last with "dona eis requiem sempiternam" (give them rest eternal).
