Interfaith dialogue is essential for several reasons according to Catholic theologian Dr Gerard Hall SM. First, in our postmodern world no single religion can claim to have the sole truth. Second, in a democracy all religions have a right to practice freely. Third, in secular societies the role of organized religion is ambiguous. Fourth, as global citizens we must care for all humanity regardless of borders. Fifth, Australia is a multicultural society requiring dialogue between religious groups and indigenous peoples. Sixth, spirituality exists outside religion so faiths must engage all voices. Seventh, religions should promote justice for marginalized groups. Eighth, dialogue is fundamental to human dignity and community.
