Apologia Pro Vita Sua

According to Wikipedia: "Apologia Pro Vita Sua (Latin: A defense of his life) is the classic defense by John Henry Newman of his religious opinions, published in 1864 in response to what he saw as an unwarranted attack on him, the Catholic priesthood, and Roman Catholic doctrine by Charles Kingsley. The work quickly became a bestseller and has remained in print to this day. The work was tremendously influential in turning public opinion for Newman, and in establishing him as one of the foremost exponents of Catholicism in England....Venerable John Henry Newman, CO (21 February 1801 – 11 August 1890) was a Roman Catholic priest and Cardinal who converted to Roman Catholicism from Anglicanism in October 1845. In early life, he was a major figure in the Oxford Movement to bring the Church of England back to its Catholic roots. Eventually his studies in history persuaded him to become a Roman Catholic. Both before and after becoming a Roman Catholic, he wrote a number of influential books, including Via Media, Essay on the Development of Christian Doctrine (1845), Apologia Pro Vita Sua (1865-66) and the Grammar of Assent (1870)."
