This was prophetic of evil days in the future and the reign of Alfonso proved to be the culminating point of Jewish prosperity. The capital and commerce of the land were to a great extent in their hands; they managed its finances and collected its revenues. King, noble and prelate entrusted their affairs to Jews, whose influence consequently was felt everywhere. To precipitate them from this position to the servitude prescribed by the canons required a prolonged struggle and may be said to have taken its remote origin in an attempt at their conversion. In 1263 the Dominican Fray Pablo Christiá, a converted Jew, challenged the greatest rabbi of the day, Moseh aben Najman, to a disputation which was presided over by Jaime I in his Barcelona palace. Each champion of course boasted of victory; the king dismissed Nachmanides not only with honor but with the handsome reward of three hundred pieces of gold, but he ordered certain Jewish books to be burnt and blasphemous passages in the Talmud to be expunged.[270] He further issued a decree ordering all his faithful Jews to assemble and listen reverently to Fray Pablo whenever he desired to dispute with them, to furnish him with what books he desired, and to defray his expenses, which they could deduct from their tribute.[271] Two years later Fray Pablo challenged another prominent Hebrew, the Rabbi Ben-Astruch, chief of the synagogue of Gerona, who refused until he had the pledge of King Jaime, and of the great Dominican St. Ramon de Peñafort, that he should not be held accountable for what he might utter in debate, but when, at the request of the Bishop of Gerona, Ben-Astruch wrote out his argument, the frailes Pablo and Ramon accused him of blasphemy, for it was manifestly impossible that a Jew could defend his strict monotheism and Messianic belief without a course of reasoning that would appear blasphemous to susceptible theologians. The rabbi alleged the royal pledge; Jaime proposed that he should be banished for two years and his book be burnt, but this did not satisfy the Dominican frailes and he dismissed the matter, forbidding the prosecution of the rabbi except before himself. Appeal seems to have been made to Clement IV, who addressed King Jaime in wrathful mood, blaming him for the favor shown to Jews and ordering him to deprive them of office and to depress and trample on them; Ben-Astruch especially, he said, should be made an example without, however, mutilating or slaying him.[272] This explosion of papal indignation fell harmless, but the zeal of the Dominicans had been inflamed and in laboring for the conversion of the Jews they not unnaturally aroused antagonism toward those who refused to abandon their faith. So long before as 1242, Jaime had issued an edict, confirmed by Innocent IV in 1245, empowering the Mendicant friars to have free access to Juderías and Morerías, to assemble the inhabitants and compel them to listen to sermons intended for their conversion.[273] The Dominicans now availed themselves of this with such vigor and excited such hostility to the Jews that Jaime was obliged to step forward for their protection. He assured the aljamas that they were not accountable for what was contained in their books, unless it was to the dishonor of Christ, the Virgin and the saints, and all accusations must be submitted to him in person; their freedom of trade was not to be curtailed; meat slaughtered by them could be freely exposed for sale in the Juderías, but not elsewhere; dealing in skins was not to be interfered with; their synagogues and cemeteries were to be subject to their exclusive control; their right to receive interest on loans was not to be impaired nor their power to collect debts; they were not to be compelled to listen to the friars outside of their Juderías, because otherwise they were liable to insult and dishonor, nor were the frailes when preaching in the synagogues to be accompanied by disorderly mobs, but at most by ten discreet Christians; finally, no novel limitations were to be imposed on them except by royal command after hearing them in opposition.[274]
