Agnus Dei (Latin) [from agnus lamb + deus god] Lamb of God; originating in the New Testament: "The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world" (John 1:29). It is applied to various emblems, cakes, anthems, etc., used in the services of the orthodox Christian churches. As a lamb was sacrificed and partaken of in the Jewish feast of the Passover, John said in effect: behold the true divine Paschal Lamb. However, the original idea that impurity is burnt out by the divine fire from the radiant source within each person was perverted, both in the case of agni and the Lamb of God, into the idea of vicarious atonement (cf SD 2:383).
