Pseudo-Jerome
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.
But we must consider that here the Lord changes the sacrifice without changing the time; so that we never celebrate the Cæna Domini before the fourteenth moon. He who celebrates the resurrection on the fourteenth moon, will celebrate the Cæna Domini on the eleventh moon, which was never done in either Old or New Testament.
