In the Old Covenant bread and wine were offered in a thanksgiving sacrifice as a sign of grateful acknowledgment to the Creator as the giver and sustainer of life. Melchizedek, who was both a priest and king (Genesis 14:18; Hebrews 7:1-4), offered a sacrifice of bread and wine. His offering prefigured the offering made by Jesus, our high priest and king (Hebrews 7:26; 9:11; 10:12). The remembrance of the manna in the wilderness recalled to the people of Israel that they live – not by earthly bread alone – but by the bread of the Word of God (Deuteronomy 8:3). The unleavened bread at Passover and the miraculous manna in the desert are the pledge of God’s faithfulness to his promises. Jesus gave a new and definitive meaning to the blessing of the bread and the cup when he instituted the “Lord’s Supper” or “Eucharist”. He speaks of the presence of his body and blood in this new meal. When at the Last Supper Jesus described his blood “poured out for many for the forgiveness of sins” (Matthew 26:28), he was explaining his coming crucifixion as a sacrifice for sins. His death on the cross fulfilled the sacrifice of the paschal lamb. That is why John the Baptist called him the “Lamb of God who takes away the sins of the world.”
