Prominent ecclesiastics would naturally follow the lines laid down by their Papal superiors. The attitude of those whose lives mark epochs in the history of Christianity and who had more to do almost with the shaping of the policy of the Church at many times than the Popes themselves, can be quoted readily to this same effect. Neander has called particular attention to St. Bernard's declarations with regard to the evils that would follow any tolerance of such an abuse as the persecution of the Jews. "The most influential men of the Church protested against such un-Christian fanaticism. When the Abbot Bernard of Clairvaux was rousing up the spirit of the nations to embark in the second crusade, and issued for this purpose, in the year 1146, his letters to the Germans (East Franks), he at the same time warned them against the influence of those enthusiasts who strove to inflame the fanaticism of the people. He declaimed against the false zeal, without knowledge, which impelled them to murder the Jews, a people who ought to be allowed to live in peace in the country." But it has been said that there are decrees against Jewish physicians, issued especially in the south of France, by various councils and synods of the Church. Attention needs to be called at once to the fact that these are entirely local regulations and have nothing to do with the attitude of the Church as a whole, but represent what the ecclesiastical authorities of a particular part of the country deem necessary for some special reason in order to meet local conditions. Indeed at the end of the thirteenth and the early fourteenth century, when these decrees were being issued in France, full liberty was allowed in Italy, and there were no restrictions either as to medical practice or education founded on adhesion to Judaism.
