Why the New Covenant in my Blood? (BC 35; Luke 22:20)

Christ celebrates passover with his disciples. We would think that this is just a passover meal, but Christ provides a twist. He is the passover lamb, the sacrifice, the one who confirms the covenant, and the one who feasts with his people. Certainly, passover is part of the Lord's Supper, but passover is part of the Lord's Supper.
