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.
(Mor. ii. 37) When His Passion was approaching, He is said to have taken bread and given thanks. He therefore gave thanks, who took upon Him the stripes of other men’s wickedness; He who did nothing worthy of smiting, humbly gives a blessing in His Passion, to shew us, what each should do when beaten for his own sins, since He Himself bore calmly the stripes due to the sin of others; furthermore to shew us, what we who are the subjects of the Father should do under correction, when He who is His equal gave thanks under the lash.
