Eleven scholars explore the complex relationships between religious and ethnic identity within the nine major Christian traditions in Canada. The contributors discuss the ways in which changes in the ethnic composition of these traditions influence religious practice and identity, as well as how the nine religious traditions influence communal and individual ethnic identities. An introductory chapter by Paul Bramadat and David Seljak provides a thorough discussion of the theoretical, historical, and empirical issues involved in the study of Christianity and ethnicity in Canada.
