Creating a profound, intelligent vision of angels based on evolutionary science and the best of the Western religious tradition, Matthew Fox and Rupert Sheldrake chart new territory in the relationship between religion and science. When was the last time a scientist and a theologian discussed angels together?  What are angels? Many people believe in angels, but few can define these enigmatic spirits. Now visionary theologian Matthew Fox and acclaimed biologist Rupert Sheldrake—pioneers in modern religious thinking and scientific theory—launch a groundbreaking exploration into the ancient concept of the angel and restore dignity, meaning, and joy to our time-honored belief in these heavenly beings. Their guides on this journey are voices of classical religious thought—including the great Christian mystics Dionysius the Areopagite, Hildegard of Bingen and Thomas Aquinas and the Bible itself.  They link angelic teachings up with some startling findings of modern physics and evolutionary theory. Their discovery: Angels are far greater and more powerful beings than we ever knew, and our belief in them can revolutionize our lives and have profound implications for the future.
