This lesson examines the Eucharist as a sacrifice, and its foreshadowing in the Old Testament — especially as seen in the Passover. In the Old Covenant, God saved the physical lives of His people, the Israelites, through the blood of a lamb. In the New Covenant, Jesus saves the spiritual lives of His people through the shedding of His own Blood. It is this sacrifice of Jesus’ Body and Blood that we commemorate every time we celebrate the Eucharist at Holy Mass.
