Leo the Great
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.
(Serm. 58.3.) He shews that the conscience of His betrayer was known to Him, not meeting his wickedness with a harsh and open rebuke, that penitence might find a readier way to one who had not been disgraced by public dismissal.
