Given increasing global migration and the importance of positive cross-cultural relations across national borders, this book offers an interdisciplinary and intercultural exploration of identity formation. It uniquely draws from theology, psychology, and sociology—engaging narrative and identity theories, migration and identity studies, and the theologies of identity and migration—and builds on them in an unprecedented study of international migrants to construct an initial theology of Christian identity in migration. New sociological research describes the social construction of religious, ethnic, and national identities among non-North American evangelical graduates who entered the United States to pursue advanced academic studies from 1983 to 2013. It provides an intercultural account of Christian identity formation in the context of migration, transnationalism, and globalization. It ultimately argues that an integral component of Christian identity-making involves the concept of migration, of movement, toward a transformation.
