What do the fall of the Roman Empire, the creation of the first universities and the rise of anticlericalism in contemporary Europe have in common? The Catholic Church has been at the center of some of the most fascinating and unknown episodes in history. From the early councils to the Reformation controversy to the secrets of medieval monasteries to the challenges of the 20th century, these pages will take you through surprising moments in the history of the Catholic Church. Do you know what role relics played in the Middle Ages? Or how the world changed with the decisions of Trent and the Second Vatican Council? That Wasn't in My Book of the Catholic Church is a journey through the Church's best-kept secrets: from the mystery of St. Peter's tomb to the tensions between early Christians, the political intrigues of the Crusades, and the unexpected link between the Tridentine Reformation and modern science. You will also discover unusual details, such as the influence of the Vatican in the formation of modern states and the decisive role of some popes at key moments in history.
