The brief literature review above demonstrates the necessity of a compre-hensive inquiry into the methodological ramifications of the “world-Christian turn”. This volume gives methodology the center stage and aspires to spark the debate on methodology. To that end, we as editors have purposely invited a diverse group of contributors from a variety of academic backgrounds (anthro-pology, religious studies, history, missiology, intercultural studies, theology, and patristics) as well as of multiple cultural and national belongings. The authors do not share a collective understanding of what ‘World Christianity’ entails. As such, the contributions exemplify the conceptual ambiguities, currently endemic in ‘World Christianity’ scholarship. All contributors were explicitly asked to foreground methodological issues and describe, where possible, how they negotiated the methodological challenges they encountered.
