The question of the truth of religion and religions is very presuppositional. It is part of a long tradition in which religion and truth have been linked together. But what can the truth of religion actually mean and how does the truth of other religions actually appear in one's own religion? The lecture elaborates the thesis that the various cultural fields each have their own conditions of truth-speaking, which cannot be reduced to a superordinate (theoretical-objective) concept of truth. If we take up this understanding of truth in the sense of truth-speaking, then we must first clarify the conditions for the success of religious truth-speaking and then ask what this means for interreligious hermeneutics. This shows that the various historical religions function very differently and have each developed their own conditions for speaking the truth, which stand side by side. The task of interreligious hermeneutics would then be to open up the different concepts of truth-speaking in the various religions in such a way that their specificity and absoluteness is preserved.
