Of the thousands of holy individuals recognized by the Catholic Church, only a fraction are considered mystics—and of those, even fewer are reputed to have performed miracles during their lifetimes. This program takes a balanced look at signs that many believe reveal God’s divine presence on Earth, such as the visions of Juan Diego and Agnes of Montepulciano; the resurrection of Christina the Astonishing; the levitations of Joseph of Cupertino; the stigmata of Francis of Assisi and Padre Pio; and healings at Lourdes. Michael Carroll, professor of sociology at the University of Western Ontario, and other experts, both religious and secular, are featured. A Discovery Channel Production. (53 minutes)
