His Name Was John: A Life of Pope John XXIII traces the life of Angelo Giuseppe Roncalli, from a poor peasant's son raised in Italy with strong faith and simplicity to his election as Pope at the age of 76. It follows his journey as a priest, Vatican diplomat (nuncio) in various countries, and finally to Cardinal, where he became known for his humanist approach. Elected unexpectedly in 1958, he was initially considered a transitional pope, but instead brought about profound change. Highlighting his role in initiating the Second Vatican Council, which reformed the Catholic Church to meet the challenges of the modern age, made him one of the most beloved Popes in history. This work provides an in-depth look at a spiritual figure who combined rural simplicity with a progressive global vision.
