Another measure of the Spanish court, calculated to deprive the accused of the last hope of acquittal, was approved by the pope. Baptized Jews, or new-Christians descended from them, frequently held bishoprics, and were naturally favorably inclined to their unfortunate and persecuted brethren in race. At the request of the Spanish court, the pope issued a bull decreeing that no bishop, vicar, or member of the upper clergy descended from a Jewish family, whether paternally or maternally, should sit as a judge in any court for the trial of heretics. From this prohibition there was only a step to the condemnation of clergy of Jewish blood to the stake. Both his own frame of mind and his political position now inclined the pope to encourage the sovereigns in the prosecution of their bloody work. He reminded them that Jesus had established his kingdom on earth solely by the extirpation of idolatry and the extermination of idolators, and he pointed to the recent victories which the Spaniards had gained over the Moslems in Granada as the reward of heaven for their efforts towards the purification of the faith--that is to say, for the burning of new-Christians and the confiscation of their goods. Had his Holiness, Sixtus IV, not been infamous as a monster of depravity, sensuality and unscrupulousness, who appointed boys that he had himself abused to bishoprics and the cardinal dignity, and who bestowed no clerical office without payment--as his contemporary, Infessura, the chancellor of Rome, has recorded--his conduct with regard to the Holy Inquisition would have been sufficient to brand him with immortal infamy. Within a short period he published the most contradictory decisions, and did not take the trouble to veil his inconsistency with the most flimsy pretense. Scarcely had he proclaimed the utmost rigors against Judaizing heretics, and appointed a tribunal of appeals, than he partly abrogated these bulls, and issued another prescribing milder proceedings to the Inquisition, only to alter this policy in its turn.
