[Late Latin Agnus Deī : Latin agnus, lamb + Latin deī, genitive of deus, god.]
Fifth section of the Ordinary of the Mass in the Roman rite; the text is taken from John i.29 (‘Behold the lamb of God’). It was added in the late 7th century to accompany the breaking of the bread. Between the 10th and 12th centuries a threefold form evolved with a contrasting middle section. It is often used in the Anglican service of Holy Communion.
