Matthew 26:17-18.
“Now the first day of the feast of unleavened bread the disciples came to Jesus, saying, Where will You that we prepare for You to eat the Passover? And He said, Go into the city to such a man, and say unto him, The Master says, My time is at hand; I will keep the Passover at your house with My disciples.”
By the first day of the feast of unleavened bread, he means the day before that feast; for they are accustomed always to reckon the day from the evening, and he makes mention of this in which in the evening the passover must be killed; for on the fifth day of the week they came unto Him. And this one calls the day before the feast of unleavened bread, speaking of the time when they came to Him, and another says on this wise, “Then came the day of unleavened bread, when the passover must be killed;” by the word “came,” meaning this, it was near, it was at the doors, making mention plainly of that evening. For they began with the evening, wherefore also each adds, when the passover was killed.
And they say, “Where will You that we prepare for You to eat the passover?” So even from this it is manifest, that He had no house, no place of sojourning; and I suppose neither had they. For surely they would have entreated him to come there. But neither had they any, having now parted with all things.
But wherefore did He keep the passover? To indicate by all things unto the last day, that He is not opposed to the law.
And for what possible reason does He send them to an unknown person? To show by this also that He might have avoided suffering. For He who prevailed over this man's mind, so that he received them, and that by words; what would He not have done with them that crucified Him, if it had been His will not to suffer? And what He did about the ass, this He did here also. For there too He says, “If any man say anything unto you, you shall say, that the Lord has need of them;” and so likewise here, “The Master says, I will keep the passover at your house.” But I marvel not at this only, that he received Him, being unknown, but that expecting to bring upon himself such enmity and implacable hostility, he despised the enmity of the multitude.
After this, because they knew him not, He gave them a sign, like as the prophet touching Saul, saying, “You shall find one going up and carrying a bottle;” and here, “carrying a pitcher.” And see again the display of his power. For He did not only say, “I will keep the passover,” but He adds another thing also, “My time is at hand.” And this He did, at once continually reminding His disciples of the passion, so that exercised by the frequency of the prediction, they should be prepared for what was to take place; and at the same time to show to themselves, and to him that was receiving Him, and to all the Jews, which I have often mentioned, that not involuntarily does He come to His passion. And He adds, “with my disciples,” in order that both the preparation should be sufficient, and that the man should not suppose that He was concealing Himself.
“Now when the evening had come, He sat down with the twelve disciples.” Oh the shamelessness of Judas! For he too was present there, and came to partake both of the mysteries, and of the meal, and is convicted at the very table, when although he had been a wild beast, he would have become tame.
For this cause the evangelist also signifies, that while they are eating, Christ speaks of His betrayal, that both by the time and by the table he might show the wickedness of the traitor.
For when the disciples had done, as Jesus had appointed them, “when the evening had come, He sat down with the twelve. And as they did eat, He said,” we are told, “Verily, I say unto you, that one of you shall betray me.” And before the supper, He had even washed his feet. And see how He spares the traitor. For He said not, such a one shall betray me; but, “one of you,” so as again to give him power of repentance by concealment. And He chooses to alarm all, for the sake of saving this man. Of you, the twelve, says He, that are everywhere present with me, whose feet I washed, to whom I promised so many things.
Intolerable sorrow thereupon seized that holy company. And John indeed says, they “were in doubt, and looked one upon another,” and each of them asked in fear concerning himself, although conscious to themselves of no such thing. But this evangelist says, that “being exceeding sorrowful, they began every one of them to say unto Him, Is it I, Lord? And He answered and said, He it is, to whom I shall give a sop, when I have dipped it.”
Mark at what time He discovered him. It was when it was His will to deliver the rest from this trouble, for they were even dead with the fear, wherefore also they were instant with their questions. But not only as desiring to deliver them from their distress He did this, but also as willing to amend the traitor. For since after having often heard it generally, he continued incorrigible, being past feeling, He being minded to make him feel more, takes off his mask.
For when being sorrowful they began to say, “Is it I, Lord? He answered and said, He that dips with me in the dish, the same shall betray me. The Son of Man goes, as it is written of Him, but woe to the man by whom the Son of Man is betrayed. It had been good for that man if he had not been born.”
Now some say that he was so bold as not to honor his Master, but to dip with Him: but to me Christ seems to have done this too, to shame him the more, and bring him over to a better disposition. For this act again has something more in it.
2. But these things we ought not to pass by at random, but they should be instilled in our minds, and wrath would find no place at any time.
For who, bearing in mind that supper, and the traitor sitting at meat with the Saviour of all, and Him who was to be betrayed thus meekly reasoning, would not put away all venom of wrath and anger? See at any rate how meekly He conducts Himself towards him, “The Son of Man goes, as it is written of Him.”
And these things again He said, both to restore the disciples, that they might not think the thing was a sign of weakness, and to amend the traitor.
“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.” See again in His rebukes His unspeakable meekness. For not even here with invective, but more in the way of compassion, does He apply what He says, but in a disguised way again; and yet not his former senselessness only, but his subsequent shamelessness was deserving of the utmost indignation. For after this conviction he says, “Is it I, Lord?” Oh insensibility! He inquires, when conscious to himself of such things. For the evangelist too, marvelling at his boldness, says this. What then says the most mild and gentle Jesus? “You say.” And yet He might have said, O thou unholy, thou all unholy one; accursed, and profane; so long a time in travail with mischief, who hast gone your way, and made satanical compacts, and hast agreed to receive money, and hast been convicted by me too, do you yet dare to ask? But none of these things did He say; but how? “You say?” fixing for us bounds and rules of long suffering.
But some one will say, Yet if it was written that He was to suffer these things, wherefore is Judas blamed, for he did the things that were written? But not with this intent, but from wickedness. For if you inquire not concerning the motive, you will deliver even the devil from the charges against him. But these things are not, they are not so. For both the one and the other are deserving of countless punishments, although the world was saved. For neither did the treason of Judas work out salvation for us, but the wisdom of Christ, and the good contrivance of His fair skill, using the wickednesses of others for our advantage.
