Besides Innocent III, many of the Popes of the twelfth and thirteenth centuries issued similar decrees as to the Jews. It may be recalled that this was the time when the Papacy was most powerful in Europe and when its decrees had most weight in all countries. Alexander II, Gregory IX, and Innocent IV all issued formal documents demanding the protection of the Jews, and especially insisting that they must not be forced to receive Baptism nor disturbed in the celebration of their festivals. Clement VI did the same thing in the next century, and even offered them a refuge from persecution throughout the rest of France at Avignon. Distinguished Jewish scholars, who know the whole story from careful study, have given due credit to the Popes for all that they did for their people. They have even declared that if the Jews were not exterminated in many of the European countries it was because of the protection afforded by the Church. We have come to realize in recent years that persecution of the Jews is not at all a religious matter, but is due to racial prejudice and jealousy of their success by the peoples among whom they settle. All sorts of pretexts are given for this persecution at all times. Formal Church documents and the personal activities of the responsible Church officials show that during the Middle Ages the Church was a protector and not a persecutor of the Jews. There is abundant historical authority for the statement that the Popes were uniformly beneficent in their treatment of the Jews. In order to demonstrate this there is no need to quote Catholic historians, for non-Catholics have been rather emphatic in bringing it out. Neander, the German Protestant historian, for instance, said: "It was a ruling principle with the Popes after the example of their great predecessor, Gregory the Great, to protect the Jews in the rights which had been conceded to them. When the banished Popes of the twelfth century returned to Rome, the Jews went forth in their holiday garments to meet them, bearing before them the 'thora,' and Innocent II, on an occasion of this sort, blessed them." English non-Catholic historians can be quoted to the same effect. The Anglican Dean Milman, for instance, said: "Of all European sovereigns, the Popes, with some exceptions, have pursued the most humane policy towards the Jews. In Italy, and even in Rome, they have been more rarely molested than in the other countries." Hallam has expressed himself to the same effect, especially as regards the protection afforded to the Jew by the laws of the Church from the injustice of those around him. Laws sometimes fail of their purpose and the persecuting spirit of the populace is often hard to control, but everything that the central authority could do to afford protection was done and essential justice was enshrined in the Church laws.
