A Study on the Medieval Papal Perception of the Jews

历史资料没有告诉我们教皇对第一次十字军东征时基督徒屠杀犹太人的任何明确态度，而教皇似乎经常谴责对仪式谋杀的一再指控。但教皇们并没有保持一致的态度，这表明了对罗马犹太社区和教皇之间关系的研究。因此，他们的关系在社会背景下发生了变化，教皇对犹太人的态度也随之发生了变化。

Historical sources do not tell us any clear papal attitude toward the massacre of the Jews by Christians on the occasion of the First Crusade, whereas it seems that the popes often condemned the repeated accusations against the ritual murder. But the popes did not hold a consistent attitude, as demonstrates an examination of the relationships between the Jewish community in Rome and the popes. Therefore it must have been that their relationships changed in the social context and papal attitude toward the Jews also changed according to it.
