Book excerpt: South Asians make up one of the largest diasporas in the world and Christians form a relatively large share of it. Christians from the Indian subcontinent have successfully transplanted themselves all over the globe, and many from different faith backgrounds have embraced Christianity at overseas locations. This volume includes biblical reflections on diasporic life, charts the historical and geographical spread of South Asian Christianity, and closes with a call to missional living in diaspora. It analyzes how migrants revive Christianity in adopted host nations and ancestral homelands. This book portrays the fascinating saga of Christians of South Asian origin who have pitched their tents in the furthest corners of the globe and showcases triumphs and challenges of scattered communities. It presents the contemporary religious experiences from a plethora of discrete perspectives. It deals with issues such as community history, struggles of identity and belonging, linkage of religious and cultural traditions, preservation and adaptation of faith practices, ties between ancestral homeland and host nation, and diasporic moral dilemmas in diaspora. This book argues that human scattering amplifies diversity within Christianity and for the need for hetrogeneous unity amidst great diversities.
