The Orthodox migration in the West matters, despite its unobtrusive presence. And it matters in a way that has not yet been explored in social and religious studies: in terms of size, geographical scope, theological input and social impact. This book explores the adjustment of Orthodox migrants and their churches to Western social and religious contexts in different scenarios. This variety is consistent with Orthodox internal diversity regarding ethnicity, migration circumstances, Church-State relations and in line with the specificities of the receiving country in terms of religious landscape, degree of secularisation, legal treatment of immigrant religious institutions or socio-economic configurations. Exploring how Orthodox identities develop when displaced from traditional ground where they are socially and culturally embedded, this book offers fresh insights into Orthodox identities in secular, religiously pluralistic social contexts.
