Over the past 30 years or so scholars in the social sciences and politicians alike have increasingly focused their attention on the effect of migration in European societies. This has resulted in theories of multiculturalism and more recently theories of cultural, ethnic, and religious diversity. This paper raises the question of how such theories are reflected in religious education in the Danish school system. Based on analyses of a survey among pupils in their final year in upper secondary schools, it is argued that non-confessional religious education is one way of enhancing religious tolerance.
