“Norris Chumley traverses a spiritual landscape unfamiliar to most Westerners. . . . Take this book and read. Even better, read this book and accept its invitation to pray.” —Diana Butler Bass, author of A People's History of Christianity Norris Chumley presents a lavishly illustrated companion to the PBS documentary Mysteries of the Jesus Prayer. Readers can follow Chumley on a pilgrimage through the holiest sites of the early Christian world as he searches for modern-day practitioners of the ancient Eastern mystical tradition and its most sacred prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner." This beautifully illustrated volume includes black-and-white and full-color images of the author's travels through Eastern Europe, including rare pictures from visits to holy sites where photographers are only rarely granted access.
