The Sentencia-Estatuto threatened to introduce a new principle into public and canon law, both of which had always upheld the brotherhood of Christians and had encouraged conversions by prescribing the utmost favor for converts. Nicholas V was appealed to and responded, September 24, 1449, with a bull declaring that all the faithful are one; that the laws of Alfonso X and his successors, admitting converts to all the privileges of Christians, were to be enforced and he commissioned the Archbishops of Toledo and Seville, the Bishops of Palencia, Avila and Córdova, and the Abbot of San Fagun to excommunicate all who sought to invalidate them.[370] More than this seems to have been needed and, in 1450, he formally excommunicated Pedro Sarmiento and his accomplices as the authors of the Sentencia-Estatuto and again, in 1451, he repeated his bull of 1449. Finally, in the same year the synods of Vitoria and Alcalá condemned it and Alfonso de Montalvo, the foremost jurist of the time, pronounced it to be illegal.[371] It never, in fact, was of binding force, but the effort made to set it aside shows how dangerous a menace it was and how it expressed a widespread public opinion. It was the first fitful gust of the tornado. Toledo remained the hot-bed of disturbance. In 1461 the martial Archbishop, Alonso Carrillo commissioned the learned Alonso de Oropesa, General of the Geronimites to investigate the cause of dissension. He did so and reported that there were faults on both sides and, at the request of the archbishop, he proceeded to write his _Lumen ad Revelationem Gentium_ to prove the unity of the faithful, but, while he was engaged in this pious labor the inextinguishable feud broke out afresh.[372] Any chance disturbance might bring this about and the opportunity was furnished in 1467, when the canons, who enjoyed a revenue based on the bread of the town of Maqueda, farmed it out to a Jew. Alvaro Gómez, an alcalde mayor, was lord of Maqueda; his alcaide beat the Jew and seized the bread for the use of the castle; the canons promptly imprisoned the alcaide and summoned Gómez to answer. When he came the quarrel grew bitterer; the Count of Cifuentes, leader of one of the factions of the city and protector of the Conversos, espoused the cause of Gómez, while Fernando de la Torre, a leader of the Conversos, hoping to revenge the defeat of 1449, boasted that he had at command four thousand well-armed fighting men, being six times more than the Old Christians could muster. Matters were ripe for an explosion and, on July 21st, at a conference held in the cathedral, the followers of the two parties taunted each other beyond endurance; swords were drawn and blood polluted the sanctuary, though only one man was slain. The canons proceeded to fortify and garrison the cathedral, which was attacked the next day. The clergy, galled by the fire of the assailants, to create a diversion, started a conflagration in the calle de la Chapineria, which
