This expanded anniversary edition offers the complete text of the letter, along with thought-provoking commentary by Myles N. Sheehan, SJ, MD. As a priest and a physician who was trained in geriatrics and specialized in palliative care, Dr. Sheehan approaches the topic of suffering from firsthand experience and extends his warm compassion to readers. This edition incorporates relevant biographical elements of John Paul II's life and of the respective historical period. It also makes the content of the papal document more accessible and places it in the context of recent world events, including September 11th, the wars in Afghanistan and Iraq, and gun violence incidents in schools and public places across the nation. Each of the eight sections of the original document contains insightful questions suited for individual or group use, applicable prayers, and ideas for meaningful action, inviting readers to personally respond to the mystery of suffering.
