This is a bold and daring call for a revitalized Christian ecumenism to care for the soul of the world. The German author, who is a Lutheran minister and educator, focuses on Spirit as cosmic power (the earth and creativity), as psychic power (dealing with global threats and psychic numbing), and as social and ecclesial power (working in solidarity with others for peace, justice, and the integrity of creation). Muller-Fahrenholz believes that a courageous and compassionate looking after the world is the best antidote to contemporary cynicism, fundamentalism, and violentism. He also presents a cogent case for churches and Christians to share burdens. God's Spirit speaks forcefully to the tremendous revisionary work which must be done on the relationship of the church to the world.
