Luke 22:3

Having already said that the Chief Priests sought means how they might slay Jesus without incurring any danger, he next goes on to relate the means which occurred to them, as it is said, Then entered Satan into Judas.

Satan entered into Judas not by force, but finding the door open. For forgetful of all that he had seen, Judas now turned his thoughts solely to covetousness.

St. Luke gives his surname, because there was another Judas.

And he adds, one of the twelve, since he made up the number, though he did not truly discharge the Apostolic office. Or the Evangelist adds this, as it were for contrast sake. As if he said, “He was of the first band of those who were especially chosen.”

There is nothing contrary to this in what John says, that after the sop Satan entered into Judas; seeing he now entered into him as a stranger, but then as his own, whom he might lead after him to do whatsoever he willed.

, Observe the exceeding iniquity of Judas, that he both sets out by himself, and that he does this for gain. It follows, And he went his way, and communed with the chief priests and captains.

The magistrates here mentioned were those appointed to take care of the buildings of the temple, or it may be those whom the Romans had set over the people to keep them from breaking forth into tumult; for they were seditious.

By covetousness then Judas became what he was, for it follows, And they covenanted to give him money. Such are the evil passions which covetousness engenders, it makes men irreligious, and compels them to lose all knowledge of God, though they have received a thousand benefits from Him, nay, even to injure Him, as it follows, And he contracted with them.

That is, he bargained and promised. And sought opportunity to betray him to them, without the crowds, that is, when he saw Him standing by Himself apart, in the absence of the multitude.

Now many shudder at the wickedness of Judas, yet do not guard against it. For whosoever despises the laws of truth and love, betrays Christ who is truth and love. Above all, when he sins not from infirmity or ignorance but after the likeness of Judas seeks opportunity, when no one is present, to change truth for a lie, virtue for crime.

In the Creator, however, the two courses were perfectly compatible, both the predestination before the ages and the revelation at the end thereof, because that which He both fore-ordained and revealed He also in the intermediate space of time announced by the pre-ministration of figures, and symbols, and allegories. But because (the apostle) subjoins, on the subject of our glory, that “none of the princes of this world knew it, for had they known it they would not have crucified the Lord of glory,” the heretic argues that the princes of this world crucified the Lord (that is, the Christ of the rival god) in order that this blow might even recoil on the Creator Himself. …

157. Matthew proceeds thus: “Then one of the twelve, who is called Judas [of] Scarioth, went unto the chief priests, and said unto them, What will ye give me, and I will deliver Him unto you? And they covenanted with him for thirty pieces of silver;” and so on down to the words, “And the disciples did as Jesus had appointed them, and they made ready the passover.” Nothing in this section can be supposed to stand in any contradiction with the versions of Mark and Luke, who record this same passage in a similar manner. …

2. It was after this bread, then, that Satan entered into the Lord’s betrayer, that, as now given over to his power, he might take full possession of one into whom before this he had only entered in order to lead him into error. For we are not to suppose that he was not in him when he went to the Jews and bargained about the price of betraying the Lord; for the evangelist Luke very plainly attests this when he says: “Then entered Satan into Judas, who was surnamed Iscariot, being one of the twelve; and he went his way, and communed with the chief priests.” Here, you see, it is shown that Satan had already entered into Judas. His first entrance, therefore, was when he implanted in his heart the thought of betraying Christ; for in such a spirit had he already come to the supper. …

Ah ! how great is the blindness of the traitor! Even partaking of the mysteries, he remained the same; and admitted to the most holytable, he changed not. And this Luke shows by saying, that after this Satan enteredinto him, not as despising the Lord’s body, but thenceforth laughing to scorn the traitor’s shamelessness. For indeed his sin became greater from both causes, as well in that he came to the mysteries with such a disposition, as that having approached them, he did not become better, either from fear, or from the benefit, or from the honor. But Christ forbad him not, although He knew all things, that thou mightest learn that He omits none of the things that pertain to correction. Wherefore both before this, and after this, He continually admonished him, and checked him, both by deeds, and by words; both by fear, and by kindness; both by threatening, and by honor. …
