This is study about religion, xenophobic opinion, and support for Radical Right Populist Parties during their phase of initial mobilization in Sweden. It deals with two issues of investigation. First, are the opinions of regular church attenders xenophobic or non-xenophobic? Second, are the opinions of people who live in municipalities with a relatively high proportion of churchgoers more or less xenophobic? The main data of this study are the Swedish National Election Study of 2002, but the article also presents data on the characteristics of the Swedish municipalities. The findings show that church attendance is associated with non-xenophobic opinions such as support for refugee entries and for transforming Sweden into a multi-cultural society. While regular attendance in the Church of Sweden does not show any correlation with xenophobia, people attending Evangelical free churches show strong non-xenophobic opinions. Indeed, people living in municipalities with a marked presence of Evangelical free churchgoers show more non-xenophobic opinions than individuals in other municipalities. Along with individual effects, this indicates contextual religious effects on xenophobic opinion. Both individual and contextual religious effects tend to decrease xenophobic opinion.
