Using the Weberian/Bourdieusian field theory and a representative National Congregation Study (NCS), we measure and compare the activities and resources of established and newcomer congregations across all major religious traditions in Switzerland. As expected, establishment status is linked to strong privileges for the established groups. Other than expected, established groups do not seem to compete with newcomer groups by using exclusion strategies, but explicitly seek ecumenical and interreligious contacts and are very tolerant concerning individual social and religious diversity. We suggest that this does not contradict the Weberian/Bourdieusian field theory, but can itself be seen as a strategy by established groups to preserve their threatened establishment status.
