This is a guide for individuals and groups to come together around the notion and practice of Just Peace, a holistic approach to peacemaking and social justice. Adopting a fully global perspective, the volume elaborates the insights and convictions of An Ecumenical Call to Just Peace (also enclosed), the culminating statement of the WCCs decade-long effort to understand and address conflict, violence, and injustice: The Decade to Overcome Violence. The Just Peace Companion expands on the key biblical, theological and ethical considerations of Just Peace, invites further exploration and critique, and offers examples of best practices for building peace with justice. Like the Call itself, the Just Peace Companion centres on four crucial venues of Just Peace, focusing on peace in the community, in the marketplace, with the earth, and among peoples. The project and the new edition, which adds learnings from the landmark International Ecumenical Peace Convocation in Jamaica in May 2011, was coordinated by former WCC general secretary Konrad Raiser.
