From the age of fifteen, dogma has been the fundamental principle of my religion: I know no other religion; I cannot enter into the idea of any other sort of religion; religion, as a mere sentiment, is to me a dream and a mockery.
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).
