For every high priest is appointed to offer both gifts and sacrifices. Therefore it is necessary that this One also have something to offer (Hebrews 8:3).
The Catholic Faith is a ritualistic sacrificial cult where God is sacrificed back to God in the Mass. Other sacrificial cults, such as the death cult of Islam and pagan cults, offer God something that he never wanted. In the Catholic Mass, however, the ancient Jerusalem temple cult is fulfilled and continued. Jesus makes this explicit not only by describing himself as a sacrificial lamb, but also by describing his body as a Temple (John 2: 18-22). Sacrifices occur in temples, but this temple cult is wherever Jesus is present. He is physically present in the Eucharist, which is in every “temple” or Church where a Mass is offered. Lambs give us their living flesh to feed upon and nourish us. Even more remarkably, the helpless lambs have no way to defend themselves against a determined predator other than to come together in a flock as one body and allow one of them to be killed and eaten to satiate the predator in order to save the others.
This gruesome reality is fallen nature’s deformed version of God’s original plan. One day the natural order will revert to the way it was intended to be before sin wrecked the world:
The wolf shall live with the lamb, the leopard shall lie down with the kid, the calf and the lion and the fatling together, and a little child shall lead them (Isaiah 11:16).
The herding instinct of lambs is unbelievably strong. Those who work with them will attest that separating a lamb from the rest of the flock is not easy. The animals will squirm and resist. However, once two or three lambs have been separated, the remaining flock will reform and follow wherever they are led. Even in slaughterhouses after the first animals are led down the passage to the killbox, the remaining animals will bleat anxiously and do what they can to join their fellows. They do this willingly even though the smell of fear, blood, and death is already in the air.
