8Christianity is vibrant and growing in the non-western "majority" world and Christianity is changing as a result. Pachuau surveys the current trending approaches to recognizing and investigating "world Christianity" and explores the salient features of the demographic changes that mark a measurable shift in the center of gravity from the northwest part of the globe to the southern continents. This shift is not just geographical. World Christianity is ultimately about the changing and diversifying character of Christianity and a renewed recognition of the dynamic universality of Christian faith itself: Christianity is a shared religion in that people of different cultures and societies make it their own while being transformed by it. Christanity is translatable and adaptable to all cultures while challenging each with its transformative power. Pachuau also charts the theological reestablishment of the missionary enterprise founded on understandings of God's mission in the world (mission Dei), a mission of cross-cultural gospel diffusion for missionary advocates in the majority world but one of near neighbor missional engagement for the contagious Charismatic Christianity of the majority world. This book is both a descriptive study and a thoughtful analysis of world Christianity's demographics, life, representation, and thought. The book an also gives an account of the historical emergence of World Christianity and its theological characteristics using a methodology that stresses the productive tension between the universal and particular in understanding a fundamentally adaptable Christian faith. Lalsangkima Pachuau offers us a brilliant overview of the promise of historically and theologically researching and exploring Christianity as a global religion. - Jayakiran Sebastian, United Lutheran Seminary, Gettysburg, PA.
