Abstract
The discourse over secularization has undergone a pronounced change. In this context the debate over the social role of religions in post-modern societies started again about ten years ago and is still going on. This debate is also underway in political theory and political philosophy. Authors like Jürgen Habermas, Richard Rorty, Michael Walzer and Gianni Vattimo are key players in this debate. On the one hand, liberals such as Rorty tend to reduce religions to the private sphere. On the other hand, a post-secular model has developed over the last decade. Habermas is probably the most well-known of these academics. In his view, deliberative democracy needs sources for motivation as an antidote, and religions could provide such a moral resource. The paper wants to explore this discourse about the social role of religion. This analysis will focus on the contribution of religions to the debate on justice. It will be argued, that religions could be interpreted as comprehensive social practices. More precisely, religions can be regarded as cultural practices through which people live and interpret their lives. The common characteristic of all religions is that they establish a comprehensive practice that enables discussion and reflection on a transcendent dimension of reality. In plural societies, in which different forms of reasons play an important role, religions as social practices could be one important social factor, especially when we are reflecting about the sources of global justice.
