In this remarkable tour of the Catholic world, George Weigel helps us understand how Catholicism fosters what Flannery O'Connor called the habit of being. Taking the reader by the hand, Weigel embarks on a journey to Catholic landmarks as diverse as Chartres Cathedral and St. Mary's Church in Greenville, South Carolina; the Holy Sepulcher in Jerusalem and G.K. Chesterton's favorite pub; the grave of a modern martyr in Warsaw, and the Sistine Chapel. Weaving together insights from history, literature, theology, and music, Weigel uses these touchstones to illuminate the beliefs that have shaped Catholicism for two thousand years.With clarity and conviction, Weigel examines the foundations of Catholic faith and explores the topics of grace, prayer, vocation, sin and forgiveness, suffering, and-most importantly-love. Putting a dramatic face on this invitation to Catholicism, Weigel introduces some of the figures who have shaped his faith and thought-Michelangelo and Fra Angelico; Evelyn Waugh and Cardinal John Henry Newman; Father Jerzy Popieuszko and Pope John Paul II; Edith Stein and Mother Teresa-as he also shares anecdotes from his own Catholic life. To a world that sometimes seems closed and claustrophobic, he suggests, Christian humanism offers a world with windows and doors-and a skylight.In these letters, George Weigel conveys the power of a faith that is at once personal and universal, timely and eternal. His book will inspire not only the young generation of Catholics whose World Youth Day celebrations have launched an era of renewal for the Church, but also the faithful, the doubtful, and the searchers of every age.
