In this article, a novel Wittgensteinian approach to philosophy of religion is presented which uses autobiographical exposition as a way of clarifying religious concepts. After analyzing what Wittgenstein is trying to accomplish in his philosophical approach, Wittgenstein’s type of grammatical inquiry into concept formation is applied to religion in this very straightforward manner. How a child learns to use religious concepts and how people check whether the child is using these concepts correctly, reminds us of the actual role these concepts (...) play in our discourses. In the third and fourth sections, the Wittgensteinian investigation of concept formation into religion conducted in this article is used to establish that the two common criticisms, namely that a Wittgensteinian approach fails to acknowledge that for believers God is real and that religious conflicts exist, are misplaced. It is shown that a Wittgensteinian approach in philosophy of religion merits renewed attention. (shrink)
