Matthew 27:3

Let the propounders of those fables concerning intrinsically evil naturesa answer me here, whence Judas came to the acknowledgment of his sin, I have sinned in that I have betrayed righteous blood, except through the good mind originally implanted in him, and that seed of virtue which is sown in every rational soul? But Judas did not cherish this, and so fell into this sin. But if ever any man was made of a nature that was to perish, Judas was yet more of such a nature. If indeed he had done this after Christ's resurrection, it might have been said, that the power of the resurrection brought him to repentance. But he repented when he saw Christ delivered up to Pilate, perhaps remembering the things Jesus had so often spoken of His resurrection. (John 13:27.) Or, perhaps Satan who had entered into him continued with him till Jesus was given up to Pilate, and then, having accomplished his purpose, departed from him; whereupon he repented. But how could Judas know that He was condemned, for He had not yet been examined by Pilate? One may perhaps say, that he foreboded the event in his own mind from the very first, when he saw Him delivered up. Another may explain the words, when he saw that he was condemned, of Judas himself, that he then perceived his evil case, and saw that he himself was condemned.

This was a charge both against him, and against these men; against him, not because he repented, but because he did so, late, and slowly, and became self-condemned (for that he delivered Him up, he himself confessed); and against them, for that having the power to reverse it, they repented not. But mark, when it is that he feels remorse. When his sin was completed, and had received an accomplishment. For the devil is like this; he suffers not those that are not watchful to see the evil before this, lest he whom he has taken, should repent. At least, when Jesus was saying so many things, he was not influenced, but when his offense was completed, then repentance came upon him; and not then profitably. For to condemn it, and to throw down the pieces of silver, and not to regard the Jewish people, were all acceptable things; but to hang himself, this again was unpardonable, and a work of an evil spirit. For the devil led him out of his repentance too soon, so that he should reap no fruit from thence; and carries him off, by a most disgraceful death, and one manifest to all, having persuaded him to destroy himself. But mark, I pray thee, the truth shining forth on every side, even by what the adversaries both do and suffer. For indeed even the very end of the traitor stops the mouths of them that had condemned Him, and suffers them not to have so much as any shadow of an excuse that is surely shameless. For what could they have to say, when the traitor is shown to pass such a sentence on himself. He brought again the thirty pieces of silver to the chief priests, and saith, I have sinned in that I have betrayed innocent blood. And they said, what is that to us? see thou to that. And he cast down the pieces of silver in the temple, and departed, and went and hanged himself. For neither could he bear his conscience scourging him. But mark, I pray thee, the Jews too suffering the same things. For these men also, when they ought to have been amended by what they suffered, do not stop, until they have completed their sin. For his sin had been completed, for it was a betrayal; but theirs not yet. But when they too had accomplished theirs, and had nailed Him to the cross then they also are troubled. Hear, ye covetous, consider what befell him; how he at the same time lost the money, and committed the sin, and destroyed his own soul. Such is the tyranny of covetousness. He enjoyed not the money, neither the present life, nor that to come, but lost all at once, and having got a bad character even with those very men, so hanged himself.

Observe that he repents only when his sin is finished and complete; for so the Devil suffers not those who are not watchful to see the evil before they bring it to an end.

Judas, when he saw that the Lord was condemned to death, returned the money to the Priests, as though it had been in his power to change the minds of His persecutors.

(Hil. Quæst. V. et N. Test. q. 94.) Since the Chief Priests were employed about the murder of the Lord from the morning to the ninth hour, how is this proved that before the crucifixion Judas returned them the money he had received, and said to them in the temple, I have sinned, in that I have betrayed innocent blood? Whereas it is manifest that the Chief Priests and Elders were never in the temple before the Lord's crucifixion, seeing that when He was hanging on the Cross they were there to insult Him. Nor indeed can this be proved hence, because it is related before the Lord's Passion, for many things which were manifestly done before, are related after, that, and the reverse. It might have been done after the ninth hour, when Judas, seeing the Saviour dead and the veil of the temple rent, the earthquake, the bursting of the rocks, and the elements terrified, was seized with fear and sorrow thereupon. But after the ninth hour the Chief Priests and Elders were occupied, as I suppose, in the celebration of the Passover; and on the Sabbath, the Law would not have allowed him to bring money. Therefore it is to me as yet unproved on what day or at what time Judas ended his life by hanging.
