The author attempts to lay out a constructive Jewish theology of the non-Jew. He states that first he is concerned to set this theological project in its precise modern context. He wants to understand how modernity influences religious thinking about the religiosity of the other and also to what extent, if any, modernity relativizes the classic and medieval theological construction of the religious other, in this case, the non-Jew. Second, he seeks to describe in a concise, thematic way what that construction has been. How, in fact, have Jews come to terms with non-Jewish religiosity, specifically, with Christianity?
