But it is not complete. Jesus performed the ritual up to the point where the Sacrificial Lamb needs to be eaten. What is finished is His part in the sacrifice. To show that Jesus is the Lamb of God, key text need to be understood through typology. As I mentioned the hyssop branch, in Exodus 12:22, a hyssop branch is used to spread the blood of the lamb on the doorposts. It is also instructed by God that the lamb shall be unblemished with no broken bones in Exodus 12:46, and John will point out that the soldiers did not break Jesus’s legs in John 19:32-33. I would go on, but the point is that Jesus had done painstaking work to fulfill the passover meal as Himself being both the sacrificial priest and sacrificial lamb to fulfill the covenant.
Lastly, to fulfill the promise to Abraham, in Genesis 22, Isaac asked where is the lamb. Abraham said the Lord will provide. As Isaac brought the wood for his sacrifice, Jesus would bring the wood for His. As Isaac was a willing victim of the sacrifice, because he could have revolted against his father at anytime, so too was Jesus a willing victim. At the last moment, God stopped Abraham from sacrificing his son, but our Father would not spare his own Son’s life, Jesus’s life. Abraham saw a ram, though not a lamb, with its head stuck in thorns and sacrificed it, but who else’s head was stuck in thorns? Alluding to Jesus’s crown of thorns, another element that Jesus, as man, could not have controlled, so much of the prophecy is fulfilled.
In order to fulfill the new covenant with God, as the Israelites needed to eat the flesh of the Lamb, we too, must eat the flesh of the lamb through the Eucharist. Jesus is eternally sacrificed for us at every Mass as revealed in Revelations 5:6 “And between the throne and the four living creatures and among the elders, I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes”. A lamb that looks like it has been slain, but alive. Jesus finished His part on the cross and left the eating of the lamb for us to complete the Sacrifice at every Mass.
