A highly influential figure in the Church of England, John Henry Newman stunned the Anglican community in 1843, when he left his position as vicar of St. Mary's, Oxford, to join the Roman Catholic church. Perhaps no one took greater offense than Protestant clergyman Charles Kingsley, whose scathing attacks against Newman's faith and honor inspired this brilliant response. Apologia Pro Vita Sua, Newman's spiritual autobiography, explores the depths and nature of Christianity with flowing prose and a conversational style that has ensured its status as a classic.
