We conduct a multilevel examination of the relationship between religiosity and democratic citizenship norms and behaviors using International Social Survey Program data. We analyze how democratic engagement varies according to individual and national average religious involvement in 28 predominantly-Christian democracies. We find that (1) individual-level religious attendance is positively linked to both what people say (norms) and what they do (participation); (2) nations with higher aggregate national attendance participate less politically; and (3) the relationship between individual-level religious engagement and citizenship varies by national religious context. More specifically, individual religious attendance matters more where it is more distinctive (i.e., in more secular countries). Individual-level religious participation is generally conducive to citizenship, but its impact is context-dependent.
