This book covers the early biography of Pope Pius XII, covering the life story of Eugenio Pacelli (Pope Pius XII), from his childhood, diplomatic career in Germany, his appointment as Cardinal Secretary of State, and his election as the 260th Pope in 1939. Furthermore, it also covers the role of Pope Pius XII during the turbulent years of World War II, including the moral and diplomatic challenges the Vatican faced in confronting Nazi Germany. Written shortly after the end of the war (first published around 1951), this book tends to paint a very positive and supportive picture of Pius XII, portraying him as an "Angelic Shepherd" who sought to maintain peace and aid the victims of war. Beyond the political aspects, the book also explores the Pope's spiritual and personal aspects, including his dedication to ecclesiastical duties. Overall, this book is a historical document that highlights Pope Pius XII's efforts to lead the Catholic Church through one of the darkest periods in modern history.
