Some of the organizations working with interfaith dialogue are open for Humanists as well. Here is information on a large conference that may be of interest if you want to engage in such dialogue.
This December the Council for a Parliament of the World’s Religions (CPWR) based in Chicago, Illinois will be holding an international Parliament in Melbourne, Australia. Ten thousand people representing dozens of religious and faith traditions will be present from eighty different countries to learn from one another. The Parliament will run for seven days with approximately 450 events including keynote addresses, seminars, conferences, debates, performances, concerts and exhibitions. The idea is to cultivate harmony among the world’s religious communities and foster dialogue with understanding and respect between those of different beliefs.
CPWR wishes to ensure that atheists and Humanists are well-represented at the event.
