could only resist with the word. Polemics were the means of debate and political power in the hands of the Christians meant the Jews would have to loose. Christian sects arose that carried out bizarre rites (Knights Templar,etc.), while mobs wrought atrocities on whole Jewish communities. The popes at times decried and tried to prevent these popular outrages often to no avail. This did not endear the Christians to the Jews, even though there were rabbis in the midst of it who were extraordinarly tolerant for their time (HaMeiri, Aboav). Medieval Christians as well as popular culture held a deep superstitious belief in the potency of blood. Given this context of the powerful vs vanquished, it is not impossible to believe that certain Jews mocked the Christian belief and carried outtheir own acts of revenge. To say this was ever part of Judaism, or sanctioned in any way, is as obscene as the charge that the Eucharist is cannibalistic.
