A quote...
from Venerable John Henry Newman, C.O., dealing with part of today's Gospel reading:
"Judas, having once shown what he was, lost no time in carrying out his malice. He went to the Chief Priests, and bargained with them to betray his Lord for a price. Our Lord saw all that took place within him; He saw Satan knocking at his heart, and admitted there and made an honoured and beloved guest and an intimate. He saw him go to the Priests and heard the conversation between them. He had seen it by His foreknowledge all the time he had been about Him, and when He chose him. What we know feebly as to be, affects us far more vividly and very differently when it actually takes place. Our Lord had at length felt, and suffered Himself to feel, the cruelty of the ingratitude of which He was the sport and victim. He had treated Judas as one of His most familiar friends. He had shown marks of the closest intimacy; He had made him the purse-keeper of Himself and His followers. He had given him the power of working miracles. He had admitted him to a knowledge of the mysteries of the kingdom of heaven. He had sent him out to preach and made him one of His own special representatives, so that the Master was judged of by the conduct of His servant. A heathen, when smitten by a friend, said, "Et tu Brutë!" What desolation is in the sense of ingratitude! God who is met with ingratitude daily cannot from His Nature feel it. He took a human heart, that He might feel it in its fulness. And now, O my God, though in heaven, dost Thou not feel my ingratitude towards Thee? " - Meditations and Devotions
