Churches all over Europe are experiencing decline within a larger context of religious decline. One under-researched field concerns the consequences this decline has at a local organizational level. This article examines congregations experiencing growth in attendance at their regular Sunday worship services, and asks: What has caused growth in attendance among these congregations? What are the consequences of the attendance growth according to parish leadership, staff, committed volunteers and regular churchgoers? The empirical material for the study is interview and observation material from four congregations in the Church of Norway. These congregations have witnessed an increase in attendance of between 15.5% and 31.6% the last five years (2013–2017) compared to the previous five years (2008–2012). The ecclesial ideal in the Church of Norway, as in other national majority churches, has been to balance between “the core congregation” and “the folk church”. However, the Nordic pattern of “belonging without believing” or “believing in belonging” is not as strong as it used to be, and this has made “vicarious religion” more contested within congregations. A more polarized neither-nor understanding of the Sunday service can explain why the studied congregations have been able to grow within a context of decline.
