Grube proposes a framework for respectful dealing with different religions: ‘justified religious difference. The author comments on the epistemic setting of Grube’s thesis. It testifies a cognitive approach to religious faith by handling religious faith and epistemic belief as analogous argument. His criticism of the pluralist approach is not very convincing. This framework is too abstract for an interreligious dialogue. The author proposes a concept of religious faith within a web of practices, liturgical rituals. A concrete interreligious dialogue can enrich the Christian faith in its practical styling.http://www.tandfonline.com/loi/rjpt202018-04-30hb2017Dogmatics and Christian Ethic
