This book is a critical analysis of the doctrinal and political issues that led to the Vatican Council of 1869-1870. The authors, Johannes Huber and Johann Joseph Ignaz von Döllinger, were prominent German theologians who opposed the doctrine of papal infallibility. They argue that the Council's decision to declare the doctrine was based on flawed reasoning and political considerations, rather than scriptural or theological grounds. The book remains an important resource for historians and theologians interested in the Catholic Church and its role in modern society.
