Origen
Catena Aurea · Matthäusevangelium 26
Now when the even was come, he sat down with the twelve. And as they did eat, he said, Verily I say unto you, that one of yon shall betray me. And they were exceeding sorrowful, and began every one of them to say unto him, Lord, is it I? And he answered and said, He that dippeth his hand with me in the dish, the same shall betray me. The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born. Then Judas, which betrayed him, answered and said, Master, is it I? He said unto him, Thou hast said.
Such is the wont of men of exceeding wickedness, to plot against those of whose bread and salt they have partaken, and especially those who have no enmity against them. But if we take it of the spiritual table, and the spiritual food, we shall see the more abundant and overflowing measure of this man’s wickedness, who called to mind neither his Master’s love in providing carnal goods, nor His teaching in things spiritual. Such are all in the Church who lay snares for their brethren whom they continually meet at the same table of Christ’s Body.
