To truly understand the significance of the Mass, we must understand the importance of blood sacrifice to Judaism in Jesus' time. On Yom Kippur, the high priest would enter the Holy of Holies and sacrifice a goat, upon which he would symbolically place the sins of the people, and a sheep. The blood would then be sprinkled around the sacred space and over the people. Jesus offering his body and blood at the Last Supper was a deliberate extension-fulfillment-of this offering. He was the sacrificial lamb, the scapegoat, upon which the temple is rebuilt-upon which reconciliation is offered.
