There is widespread talk of a "Christian-Jewish dialogue". A dialogue between Christians and Jews is not a matter of course. In the light of the tragic history between these religious communities, the talk of a dialogue - especially in the German-speaking context - even seems more like an imposition for Judaism. A more detailed analysis of the talk of a dialogue on the level of the universal Church Magisterium of the Roman Catholic Church then brings to light rather mere rhetoric and not a deeper reflection on the theological and philosophical implications of a genuine dialogue between different revelatory religions. The superficiality goes so far that it is not even clear why dialogue should be a suitable means of encounter between Jews and Christians. This is the answer to this investigation.
