This study examines the relationship between religious involvement and civic engagement in a comparative, cross-cultural perspective. Using data from a 1996 survey of 3000 Canadians and 3000 Americans, the study assesses religion's relative contribution to civic engagement in the two settings. The study reveals that both religious tradition and, more important, church attendance play an important role in fostering involvement in civil society in both countries, even after controlling for the effects of other factors generally associated with fostering civic activity among members of society.
