The Parliament of the World's Religions met in 1993 (Chicago), 1999 (Cape Town), 2004 (Barcelona) and 2009 (Melbourne). The 1993 declaration affirmed that a common set of core values is found in the teachings of religion that provide the conditions for a sustainable world order. The present study provides the first detailed profile of the religious background, beliefs, and motivations of participants at the Parliament, drawing on data provided by 658 individuals who attended Barcelona 2004. These data profile a group of people committed both to their own religious and spiritual practices and open to engagement with the religious and spiritual practices of others. In such a context religious diversity functions as the generator of peace, not of conflict
