In this book, Msgr. Ronald Knox recounts the events and circumstances leading to his reception into the Catholic Church. This is the story of a man who awakes from his undisturbed and unreflective religion, his attempt to rationally reconstruct and justify his comfortable past and his final arrival at truth."On the other hand, it is true that there is a sense in which Catholicism can be taught, and ordinary Anglicanism cannot. For Anglicanism, generally speaking, is not a system of religion nor a body of truth, but a feeling, a tradition, its roots intertwined with associations of national history and of family life; you do not learn it, you grow into it; you do not forget it, you grow out of it."A clear, honest reflection on Knox's struggle to understand the history of his church (Church of England) and its connection to the Apostolic tradition. He finally concludes he can do no other than leave the Anglican church for the Catholic church. But it is the journey of his mind and heart driven by his brilliant, logical mind, that provides the drama and the pain that finally leads to "paying the price of unity".
