Bede the Venerable
Catena Aurea · Markusevangelium 14
And as they did eat, Jesus took bread, and blessed, and brake it, and gave to them, and said, Take, eat: this is my body. And he took the cup, and when he had given thanks, he gave it to them: and they all drank of it. And he said unto them, This is my blood of the new testament, which is shed for many. Verily I say unto you, I will drink no more of the fruit of the vine, until that day that I drink it new in the kingdom of God.
(ubi sup.) This refers to the different circumstances of the Old Testament, which was consecrated by the blood of calves and of goats; and the lawgiver said in sprinkling it, This is the blood of the Testament which God hath injoined unto you. (Heb. 9:20. vide Ex. 24:8) It goes on: Which is shed for many.
