Today, western liberal democratic societies are secular, or in other words, religion is set apart from the state. However, the beginning of the 21st century has seen a re-politicizing of the religion. This paper argues that religion plays an important role in current global politics and events. Moreover, it has been used as tool to recruit masses for a wrong cause. Hence, Interreligious and interfaith dialog can play a role of catalysts and a future trend in cultural diplomacy. The paper provides definitions of a secular and post secular society. Then, it discusses the general concept of dialogue and explores it from an interreligious and interfaith point of view as a way to mitigate the role religion has undertaken. Finally, it provides examples of what European Union has been doing in that respect.
