Bede the Venerable
Catena Aurea · Lukasevangelium 22
And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me. Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Having finished the rites of the old Passover, He passes on to the new, which He desires the Church to celebrate in memory of His redemption, substituting for the flesh and blood of the lamb, the Sacrament of His own Flesh and Blood in the figure of the bread and wine, being made a Priest for ever after the order of Melchisedech. (Ps. 110:4.) Hence it is said, And he took bread, and gave thanks, (Heb. 7:21.) as also He had given thanks upon finishing the old feast, leaving us an example to glorify God at the beginning and end of every good work. It follows, And brake it. He Himself breaks the bread which He holds forth, to shew that the breaking of His Body, that is, His Passion, will not be without His will. And gave unto them, saying, This is my body which is given for you.
