No more remarkable controversy was ever held. It occupied sixty-eight sittings, and extended, with few interruptions, over a year and nine months (from February, 1413, until the 12th November, 1414). In the foreground stands a pope, abandoned by almost the whole of Christendom, and hunted from his seat, anxious for a favorable issue, not for the glorification of the faith, but for his own temporal advancement; by his side, a baptized Jew, combating Rabbinical Judaism with Rabbinical weapons; and in the background, a frenzied Dominican preacher with his escort of flagellants, promoting a persecution of the Jews to give force to the conversionist zeal of Tortosa. The helpless, bewildered Jews could only turn their eyes to heaven, for on earth they found themselves surrounded by bitter enemies. When, at their first audience with Pope Benedict (6th February, 1413), they were asked to give their names for registration, they were seized with terror; they imagined their lives in jeopardy. The pope quieted them with the explanation that it was only a customary formality. On the whole he treated them at first with kindness and affability, the usual attitude of princes of the church when they have an end to attain. He assured them that no harm would befall them; that he had summoned them merely to ascertain whether there was any truth in Geronimo's statement that the Talmud attested the Messianic character of Jesus, and he promised them the fullest freedom of speech. At the end of the first audience he dismissed them graciously, assigned quarters to each of the notables, and gave instructions that their comfort should be cared for. A few prophesied from this friendly reception a successful issue for themselves and their cause, but they knew little of Rome and the vicegerents of God.
A few days later the disputation began. When the Jewish notables entered the audience hall, they were awe-struck by the splendor of the scene: Pope Benedict, on an elevated throne, clad in his state robes; around him the cardinals and princes of the church, resplendent in jeweled vestments; beyond them nearly a thousand auditors of the highest ranks. The little knot of defenders of Judaism trembled before this imposing and confident array of the forces of Christianity. The pope himself presided, and opened the sitting with an address to the Jews. He informed them that the truth of neither Judaism nor Christianity was to be called into question, for the Christian faith was above discussion and indisputable, and Judaism had once been true, but had been abrogated by the later dispensation. The disputation would be confined to the single question, whether the Talmud recognized Jesus as the Messiah. The Jews were consequently limited to mere defense. At a sign from the pope, the convert Geronimo stood forth, and, after a salutation of the papal toe, delivered himself of a long-winded harangue, abounding in Christian, Jewish, and even scholastic subtleties, and full of praise of the magnanimity and graciousness of the pope in endeavoring to bring the Jews into the way of salvation. His text, applied to the Jews, was a verse from Isaiah: "If ye be willing and obedient, ye shall eat the good of the land; but if ye refuse and rebel, ye shall be devoured with the sword"--which disclosed the final argument of the church. In reply, Vidal Benveniste, who had been elected spokesman by the notables, delivered a speech in Latin, which evoked a compliment from the pope. Don Vidal exposed Geronimo's malignity in threatening the sword and other punishments before the arguments on either side were heard. The pope acknowledged the justice of the reproof, and said in extenuation that Geronimo had still the boorishness derived from his Jewish origin. The notables plucked up courage to petition the pope to release them from further controversy, giving as their reason that their opponent employed scholastic methods of reasoning, in which it was impossible for them to follow him, as their faith was founded not on syllogisms but on tradition. The pope naturally declined to accede to this request, but invited them to continue the discussion on the following day, and had them escorted to their quarters by officers of high rank.
