The book opens with an impressive article by Georg Kretschmar. The relationship and the increasing difference between Jews and Christians are determined by the way Jews and Christians have defined themselves against one another. Christians saw Jews as those who rejected Jesus, and therefore identified themselves in opposition to the Jews. The one and only Church, in origin Jewish and gentile became - by definition - anti-Jewish. One of the consequences was Auschwitz, for Jews a never-ending experience. The distinction between Jews and Christians is still present in modern definitions of Church. The problem remains: how can Jews and Christians be defined differently, and both be successors to the same tradition?
