The truth is that Jewish communities accepted oppression, and second-class status, provided it had definite rules which were not constantly and arbitrarily changed without warning. What they hated most was uncertainty. The ghetto offered security and even comfort of a kind. It made the observance of the law easier in many ways, by concentrating and isolating Jews. If segregation, as the church claimed, safeguarded Christians from evil Jewish contacts, equally it protected Jews from secularity.
