Popish

Papist is a pejorative term referring to the Roman Catholic Church, its teachings, practices, or adherents. The word gained currency during the English Reformation, as it was used to denote a person whose loyalties were to the Pope and the Roman Catholic Church, rather than to the Church of England. First used in 1528,papist derives (through Middle French) from Latin papa, meaning "Pope".

The term was also common in use in the Eastern Orthodox Church in the 19th century.

The word was in common use by Protestant writers until the mid-nineteenth century, as shown by its frequent appearance in Thomas Macaulay's History of England from the Accession of James II and in other works of that period, including those with no sectarian bias. It also appeared in the compound form "Crypto-Papist", referring to members of Reformed, Protestant, or nonconformist churches who at heart were allegedly Roman Catholics.Alexis Khomiakhov, a Russian lay theologian of the nineteenth century, claimed that "All Protestants are Crypto-Papists".

The word is found in certain surviving statutes of the United Kingdom, for example in the English Bill of Rights of 1688 and the Scottish Claim of Right of 1689. Under the Act of Settlement of 1701, no one who professes "the popish religion" may succeed to the throne of the Kingdom of England and the Act continues to apply to the United Kingdom and all of the Commonwealth Realms; until the Succession to the Crown Act 2013 amended it with effect from 2015, the Act of Settlement also banned from the throne anyone who married "a papist". Fears that Roman Catholic secular leaders would be anti-Protestant and would be unduly influenced from Rome arose after all allegiance to the Pope was banned in England in the reigns of Henry VIII and Elizabeth I. Jonathan Swift (1667–1745), the author of Gulliver's Travels, employed the term in his satirical essay A Modest Proposal, in which he proposed selling Irish babies to be eaten by wealthy English landlords. Daniel Defoe wrote in the popular Robinson Crusoe (1719), near the end of the novel: "... I began to regret having professed myself a Papist, and thought it might not be the best religion to die with."
