Chapter 14 does not design a general theory of religious change, but develops a multiple theoretical perspective including various theoretical elements, which are instrumental for explaining religious changes and which can be combined flexibly. In brief, they are: 1. Functional differentiation as a rule stands in a strained relationship to the integrational capacity of religious communities and churches. If, however, religious identities are linked with non-religious, for example, political, national, or economic interests, religion and church are strengthened. 2. Processes of individualization mostly have an erosive impact on religious ties. 3. In contrast to the assumptions of the market model, religious pluralism does not foster religious vitality, but actually inhibits it. In the case of conflict, though, religious diversity can fuel religious passions. Other determining factors such as government regulations of the religious sector, state spending on the welfare system, social inequality, immigration, and path dependency are also taken into account.
