We practitioners of different faiths can work together for world peace when we view different religions as essentially instruments to develop a good heart - love and respect for others, a true sense of community. The most important thing is to look at the purpose of religion and not at the details of theology or metaphysics, which can lead to mere intellectualism. I believe that all the major religions of the world can contribute to world peace and work together for the benefit of humanity if we put aside subtle metaphysical differences, which are really the internal business of each religion.
