The notion of ‘holiness’ has a long history of interpretation. In many ways, it is an ambivalent term. On the one hand, it denotes moral integrity by distinction, or ‘being set apart’. This ‘distinction’ brought with it a pejorative interpretation of ‘holiness’ as denoting some sort of hierarchical moral exclusivism, attainable only by a minority. However, holiness is an essential aspect of spirituality and in this regard it has a rich and dynamic meaning. This article aims to reappropriate ‘holiness’ for ordinary human beings in their everyday lives and to transcend the exclusivist connotations attached to the concept by broadening the idea and application of ‘holiness’ as it is found in the Christian faith tradition. In this article, the emerging church movement (ECM) shall be considered with the purpose of introducing discussions regarding holiness in faith practice today. This will be done in order to demonstrate its richness and usefulness as a key component of spiritualties today, with a specific focus on its contribution to interreligious dialogue. Interdisciplinary and/or interdisciplinary implications: This article represents interdisciplinary work related to systematic theology (ecclesiology), practical theology and spirituality (holiness and science of religion) perspectives. The authors consider a postmodern multi-religious context in relation to aspects of Christian spirituality and ecclesiology (holiness).
