Religions play a decisive role in formation of attitudes of individuals and societies toward the others. Unfortunately religions have contributed all too often in human history to the aggravation of conflicts and wars. Throughout history, we have seen brutal acts of individuals in the name of religion and violent groups within various religious traditions. Furthermore, we have to make distinctions between diverse world religions that have more or less violent in the histories. In context of a noble peace mission, throughout world, Religious representatives need to exercise their moral authority and mobilize the vast human resources of their communities in the service of peacemaking. The rest of us, in turn, must recognize the growing importance of religious factors for peacemaking and develop ways, both informal and formal, to cooperate with religious leaders and communities in promoting peace with justice.
