Popery
The words Popery (adjective Popish) and Papism (adjective Papist, also used to refer to an individual) are mainly historical pejorative words in the English language for Roman Catholicism, once frequently used by Protestants and Eastern Orthodox Christians to label their Catholic opponents, who differed from them in accepting the authority of the Pope over the Christian Church. The words were popularised during the English Reformation (1532–1559), when the Church of England broke away from the Catholic Church and divisions emerged between those who rejected papal authority and those who continued to follow Rome.
