Ancient Jewish law took a strict approach to medical relationships between Jews and non-Jews. Sages forbade Jews to provide non-Jews with medical services: to treat them, circumcise them, or deliver their babies, in order to refrain from helping pagan-idolatrous society. Such law created particularly severe social conflicts in cases of mixed societies based on joint systems. The current paper focuses on the attitude of Moses ben Maimon, a medieval Sephardic Jewish Rabbi towards providing medical service to gentiles. Following the classical (...) rabbis R. Moshe ben Maimon in his halakhic tome Mishne Torah, objected to treating non-Jews. His rigid attitude found expression in several aspects of helping and giving medical treatment to non-Jews. Despite the classical rabbinical restrictions on medical relationships between Jews and non-Jews, and his own rigid halakhic verdicts, Maimonides treated gentiles. According to one understanding, Maimonides cured Muslims for a wage, which is permitted. However, it seems that the main factor that may have facilitated Maimonides halakhic position is the identification of Islam as a non-idolatrous faith. Interestingly not only on medical issues did the Maimonides act differently than his halakhic rulings in Mishne Torah, rather in other areas as well. (shrink)
