Book excerpt: Full of larger-than-life characters, stunning acts of bravery, and heart-rending sacrifice, Tried by Fire narrates the rise and expansion of Christianity from an obscure regional sect to the established faith of the world’s greatest empire with influence extending from India to Ireland, Scandinavia to Ethiopia, and all points in between. William J. Bennett explores the riveting lives of saints and sinners, paupers and kings, merchants and monks who together—and against all odds—changed the world forever. To tell their story, Bennett follows them through the controversies and trials of their time. Challenged by official persecution, heresy, and schism, they held steadfast to the truth of Christ. Strengthened by poets, preachers, and theologians, they advanced in devotion and love. In this moving and accessible narrative, Tried by Fire speaks across centuries to offer insight into the people and events that shaped the faith that continues to shape our lives today.
