Even before the publication of his masterwork, John Henry Newman had been regarded as one of the most important religious thinkers on the 19th Century. His decision in 1945 to leave his Anglicanism behind and convert to the Roman Catholic faith was one that rocked the Victorian establishment at a time when virulent anti-Catholic feeling ran high. It was in response to one particularly vicious attach - by the Reverend Charles Kingsley - that Newman wrote his Apologia Pro Vita Sua. A humane and vivid account of the development of his ideas and his faith and a passionate defence of both, the book remains a landmark work of Victorian literature and autobiography and one that continues to resonate to this day.
