Historically, the words popery and popish have been used as derogatory terms of Catholicism. They were often used by Protestants to denote the idea that the Pope is a tyrant and his servants, Catholics, worship him. They also refer to the culture of the church, such as Baroque vestments and decoration that Protestants view as effeminate, or excessive and maudlin devotion to Mary.
Popery is distinguished from pot pourri, which is often pronounced nearly the same, except with the stress falling on the last syllable.
