The research work on Adi Christianity in particular and Adi society in general has very scanty written records from the native side. Few documents found were either unpublished or were records maintained by the missionaries which though serve as a valuable source of information but in a way inadequate. In addition, few among the Adi Christian pioneers who are aliveare facing various challenges to construct inclusive history of their own. So, this book is a first attempt of urgent search for the Origin and Development of Christianity among the Adis with special reference to Adi Baptist Union, analyzing its present development and challenges as its concluding remark. The book focuses mainly on the origin of Adi Christianity-calculating all determinants involved, and particular development of Adi Baptist Union as an organized body, with critical reflection on ongoing contextual issues that church needs to address cautiously.
