This chapter explains the general idea of a worldwide and recent increase of religions' individual and/or societal significance as the central marker of the resurgence debates and used this concept to identify the subject-matter of the present analyses as the starting-point for the present analyses. It introduces an approach that inverses the main direction of the classical resurgence debates by looking into what the author described as the black box' of a particular set of religiously affiliated organizations the Religious Non-governmental Organizations (RNGOs) that have successfully approached the United Nations (UN) for formal accreditation. In this sense, it challenges more traditional concepts of resurgence by underlining the necessity to analyse the processes inside RNGOs in order to understand their position in the UN context. Finally, it has expanded upon the concept of sedimentation' to add new dimensions to the discussion of secularization processes.
