Who represents the paschal lamb in Catholicism?
The title “Lamb of God” is not merely a metaphor, Our Lord really was a sacrificial victim and His death ended the Old Testament sacrifices; His own death permanently satisfied the debt of sin for which the lamb was annually offered. Even the process by which the lamb was prepared was reproduced in the death of Jesus Christ. The lamb had to be without blemish, was bound, brought to the temple, tied to a pillar, killed and drained of blood, was roasted on a spit in the shape of a cross with the forearms outstretched and it was consumed without a bone being broken. For an in-depth look into such details, St. Justin Martyr’s works are highly recommended.
