Visionary priest Matthew Fox and maverick biologist Rupert Sheldrake choose passages from the Bible and from the writings of three great Christian mystics--Thomas Aquinas, Hildegard of Bingen, and Dionysius the Areopagite--and read them with the new vision granted by the discoveries of modern physics, evolutionary theory, and astronomy. Our belief in angels, say Fox and Sheldrake, can enrich our inner lives, inspire our creativity, and heighten our sense of responsibility to the world and to one another.
