“Behold the lamb of God, who takes away the sin of the world” John 1:29, 36
The Lamb is an important symbol in early Christianity. It has roots in the Old Testament, where the Lamb represents sacrifice, as when Isaac asks his father, “The fire and the wood are here, but where is the lamb for a burnt offering?” When Abraham answers, “My son, God will provide for himself a lamb for a burnt offering,” Isaac understands that he, himself, is to be offered (Gen. 22:7-8).
This story is seen as an allegory for the Crucifixion; Isaac bears the wood for his own sacrifice, just as Jesus later bears His Cross. In Exod. 12: 3-5, 21, Moses teaches the Children of Israel how to prepare the Paschal lamb, and its blood brings them salvation.
The symbol of Christ the Lamb was influenced in large part by the divine revelation of John the Baptist, (Rev. 1,2:4, 4-10, 5,2 and 6). In his prophecy, angels and Elders gather to worship a lamb standing upon the throne (“To him who sits on the throne and to the Lamb be praise and honor and glory and power, for ever and ever!” Rev. 5: 6-14).
References to Christ The Lamb can be found in Isa. 53:7; Jer. 11:19; John 1:29, 36; and Apoc. 5:6, 12; 12:11; 22:1. In these passages, the blood of the Lamb washes away the sins of the people. Sometimes the lamb is used as a symbol for God’s love, as in representations of the Good Shepherd, who saves the lost lamb by taking it under His gentle protection.
