Western Christian theology has been slow to respond to the persistent challenge of global religious diversity. Though there are a few notable exceptions, in the main Christian theology continues either to ignore or to dismiss the perspectives, texts, practices, and experiences of religious others as outside the bounds of the relevant, let alone the normative. This book breaks new ground by examining how boundaries between Christianity and religious others are discursively constructed in and through theological discourse. It examines how those basic boundary-drawing processes exercise power, and how that exercise of power can distort Christian theology itself.
