Passage: During the Protestant Reformation, the Church of England (Anglicans) separated from the Roman Catholic Church. There were some Christians who were not content with the achievements of the mainstream Protestant Reformation. There also were Christians who were disappointed that the Church of England had not made corrections of what some considered to be errors and abuses. Of those most critical of the Church's direction, some chose to stay and try to make constructive changes from within the Anglican Church. They became known as "Puritans" and are described by Gourley as cousins of the English Separatists. Others decided they must leave the Church because of their dissatisfaction and became known as the Separatists.
Output:
When did the Church of England merge with the Roman Catholic Church?
