Book excerpt: ​The book discusses the theoretical and methodological challenges of an interculturally valid sociology of religion and provides insights into the autochthonous socio-religious research in Muslim societies and Asian countries. In this way, it links discourses that have so far taken place primarily independently of one another. The book goes back to a conference in Münster that questioned the Western foundation of empirical religiosity research, which reaches its limits in the non-American and non-European context, but also with regard to orthodox forms of faith in the Western context.
