A History of the Catholic Church chronicles the long journey of the Catholic Church from the Apostolic era to the modern era. It documents Jesus' role as founder, the development of doctrine, internal conflicts (heresies), and the influence of both noble and evil figures. The narrative covers the global spread of the Church, the challenges of persecution, and its resilience as guardian of the faith. It includes the living witnesses of saints and other notable figures who shaped the Church's history, and it offers a comprehensive and insightful view of the history of the Catholic Church, balancing institutional and spiritual history.
