The greatest untapped natural resource for addressing the world’s most pressing problems is the energy of religiously committed people. This volume gathers the expertise of activists, theologians and faith-based organizations to inspire and encourage churches and church people everywhere in grassroots work and advocacy for climate justice. As they make plain, no issue so violates the core of Christian convictions as the jeopardizing of human life and creation through climate change. Writing from the concrete experiences and programmatic efforts of churches in Greece, Scotland, Sweden, Finland, Germany, tropical Africa, Latin America, and the Pacific Islands, the 22 theologians and activists in this volume also address related issues of health, human rights, land and deforestation, food security, migration, divestment, as well as creation spirituality and theology. Making peace with the earth will not be easy, say the contributors. But now is the time for religious leaders, church people and organizations to make climate their priority. This volume will nurture and inform their engagement.
