This volume delves into the critical role of interreligious education and peace education, especially during times of crisis, and highlights the interaction of different religions in promoting peace. Since its inception in 1970, the World Conference on Religion and Peace (WCRP)—now known as Religions for Peace (RfP)—has emerged as the world’s largest coalition of religious communities dedicated to peace-building. Over the past 50 years, this movement has made significant strides in fostering interreligious understanding and contributing to global peace efforts. In this comprehensive exploration, readers will discover how RfP expanded its focus from specific conflicts, such as the Cold War and the nuclear threat, to broader concepts of peace that encompass justice, human rights, and the preservation of life. The book addresses crucial questions: How can we define a positive concept of peace that goes beyond the mere absence of war? What is the relationship between peace and justice? How can religions uphold human rights, contribute to the preservation of the basis of life and guide cooperative efforts? The importance of learning, education, and training in achieving these goals is emphasized throughout the publication. By tracing five decades of initiatives, declarations, and projects, this work offers valuable insights into the ongoing quest for peace and sets the stage for future endeavors in interreligious and peace education.
