The Jews slowly recovered themselves from the terrible shock; they emerged from their concealment and endeavored, with characteristic dauntless energy, to rebuild their shattered fortunes. Now, however, with diminished numbers and exhausted wealth, they had to face new enemies. Not only was Christian fanaticism inflamed and growing even stronger, but the wholesale baptisms had created the new class of Conversos, who were thenceforward to become the deadliest opponents of their former brethren. Many chiefs of the synagogue, learned rabbis and leaders of their people, had cowered before the storm and had embraced Christianity. Whether their conversion was sincere or not, they had broken with the past and, with the keen intelligence of their race, they could see that a new career was open to them in which energy and capacity could gratify ambition, unfettered by the limitations surrounding them in Judaism. That they should hate, with an exceeding hatred, those who had proved true to the faith amid tribulation was inevitable. The renegade is apt to be bitterer against those whom he has abandoned than is the opponent by birthright and, in such a case as this, consciousness of the contempt felt by the steadfast children of Israel for the weaklings and worldlings who had apostatized from the faith of their fathers gave a keener edge to enmity. From early times the hardest blows endured by Judaism had always been dealt by its apostate children, whose training had taught them the weakest points to assail and whose necessity of self-justification led them to attack these mercilessly. In 1085, Rabbi Samuel of Morocco came from Fez and was baptized at Toledo, when he wrote a tract[331] to justify himself which had great currency throughout the middle ages. Rabbi Moses, one of the most learned Jews of his time, who was converted in 1106, wrote a dissertation to prove that the Jews had abandoned the laws of Moses while the Christians were fulfilling them.[332] It was Nicholas de Rupella, a converted Jew, who started the long crusade against the Talmud by pointing out, in 1236, to Gregory IX the blasphemies which it contains against the Savior.[333] We have seen the troubles excited in Aragon by the disputatious Converso, Fray Pablo Christía, and he was followed by another Dominican convert, Ramon Martin, in his celebrated _Pugio Fidei_. In this work, which remained an authority for centuries, he piled up endless quotations from Jewish writers to prove that the race was properly reduced to servitude and he stimulated the bitterness of hatred by arguing that Jews esteemed it meritorious to slay and cheat and despoil Christians.[334] [Sidenote: _OPPRESSION OF THE JEWS_]
