English: Our shrinking world confronts us with a plurality of religion of which all claim to be "true". How should we evaluate these claims? The mainstreean Christian response to this question oscillates beween exclusism and inclusivism. These responses are explained and evaluated with references to Karl Barth (conservative exclusivism), Hendrik Kraemer and Emil Brunner (liberal exclusivism) and Karl Rahner (inclusivism). It is concluded that the responses of both the exclusivist and inclusivist boil down to the very subjective arbitrariness that they wish to avoid.
