17 Petilianus said: "We must consider, I say, and declare how far the treacherous traditor is to be accounted dead while yet in life. Judas was an apostle when he betrayed Christ; and the same man was already dead, having spiritually lost the office of an apostle, being destined afterwards to die by hanging himself, as it is written: ‘I have sinned,' says he, ‘in that I have betrayed the innocent blood; and he departed, and went and hanged himself.' The traitor perished by the rope: he left the rope for others like himself, of whom the Lord Christ cried aloud to the Father, ‘Father, those that You gave me I have kept, and none of them is lost, but the son of perdition; that the Scripture might be fulfilled.' For David of old had passed this sentence on him who was to betray Christ to the unbelievers: ‘Let another take his office. Let his children be fatherless, and his wife a widow.' See how mighty is the spirit of the prophets, that it was able to see all future things as though they were present, so that a traitor who was to be born hereafter should be condemned many centuries before. Finally, that the said sentence should be completed, the holy Matthias received the bishopric of that lost apostle. Let no one be so dull, no one so faithless, as to dispute this: Matthias won for himself a victory, not a wrong, in that he carried off the spoils of the traitor from the victory of the Lord Christ. Why then, after this, do you claim to yourself a bishopric as the heir of a worse traitor? Judas betrayed Christ in the flesh to the unbelievers; you in the spirit madly betrayed the holy gospel to the flames of sacrilege. Judas betrayed the Lawgiver to the unbelievers; you, as it were, betraying all that he had left, gave up the law of God to be destroyed by men. Whilst, had you loved the law, like the youthful Maccabees, you would have welcomed death for the sake of the laws of God (if indeed that can be said to be death to men which makes them immortal because they died for the Lord); for of those brethren we learn that one replied to the sacrilegious tyrant with these words of faith: ‘Thou like a fury takest us out of this present life; but the King of the world (who reigns for ever, and of His kingdom there shall be no end) shall raise us up who have died for His laws, unto everlasting life.' If you were to burn with fire the testament of a dead man, would you not be punished as the falsifier of a will? What therefore is likely to become of you who have burned the most holy law of our God and Judge? Judas repented of his deed even in death; you not only do not repent, but stand forth as a persecutor and butcher of us who keep the law, while you are the most wicked of traditors."
18. Augustine answered: See what a difference there is between your calumnious words and our truthful assertions. Listen for a little while. See how you have exaggerated the sin of delivering up the sacred books, comparing us in most odious terms, like some sophistical inventor of charges, with the traitor Judas. But when I shall have answered you on this point with the utmost brevity—I did not do what you assert; I did not deliver up the sacred books; your charge is false; you will never be able to prove it—will not all that smoke of mighty words presently vanish away? Or will you perchance endeavor to prove the truth of what you say? This, then, you should do first; and then you might rise against us, as against men who were already convicted, with whatever mass of invective you might choose. Here is one absurdity: behold again a second.
19. You yourself, when speaking of the foretelling of the condemnation of Judas, used these expressions: "See how mighty is the spirit of the prophets, that it was able to see all future things as though they were present, so that a traitor who was to be born hereafter should be condemned many centuries before;" and yet you did not see that in the same sure prophecy, and certain and unshaken truth, in which it was foretold that one of the disciples should hereafter betray the Christ; it was also foretold that the whole world should hereafter believe in Christ. Why did you pay attention in the prophecy to the man who betrayed Christ, and in the same place give no heed to the world for which Christ was betrayed? Who betrayed Christ? Judas. To whom did he betray Him? To the Jews. What did the Jews do to Him? "They pierced my hands and my feet," says the Psalmist. "I may tell all my bones: they look and stare upon me. They part my garments among them, and cast lots upon my vesture." Of what importance, then, that is which is bought at such a price, I would have you read a little later in the psalm itself: "All the ends of the world shall remember and turn unto the Lord; and all the kindreds of the nations shall worship before You. For the kingdom is the Lord's; and He is the governor among the nations." But who is able to suffice for the quotation of all the other innumerable prophetic passages which bear witness to the world that is destined to believe? Yet you quote a prophecy because you see in it the man who sold Christ: you do not see in it the possession which Christ bought by being sold. Here is the second absurdity: behold again the third.
