Parliament called the Westminster Assembly during a time of increasing hostility between Charles I, monarch of England and Scotland, and the Puritans. Puritans could be distinguished by their insistence that worship practices be supported implicitly or explicitly by the Bible, while their opponents gave greater authority to traditional customs. They believed the Church of England, which had separated itself from the Catholic Church during the English Reformation, was still too heavily influenced by Catholicism. They sought to rid the church and nation of any of these remaining influences. This included the Church's episcopal polity, or rule by a hierarchy of bishops. Puritans, unlike separatists, did not leave the established church. Under Charles, the Puritans' opponents were placed in high positions of authority, most notably William Laud who was made Archbishop of Canterbury in 1633, even though these "high churchmen" were in the minority. Puritans were forced to keep their views private or face fines and imprisonment. Laud promoted advocates of Arminianism, a theological perspective opposed to the Reformed theology of the Puritans. Worship practices such as kneeling at communion, bowing at the name of Christ, and the placement of communion tables at the East end of churches were also reinstated. To the Puritans, these seemed to be a step in the direction of Catholicism.
