Puritans was the name given in the 16th century to the more extreme Protestants within the Church of England who thought the English Reformation had not gone far enough in reforming the doctrines and structure of the church; they wanted to purify their national church by eliminating every shred of Catholic influence. Associated exclusively with no single theology or definition of the church (although many were Calvinists), the English Puritans were known at first for their extremely critical attitude regarding the religious compromises made during the reign of Elizabeth I. They encouraged direct personal religious experience, sincere moral conduct, and simple worship services. Worship was the area in which Puritans tried to change things most; their efforts in that direction were sustained by intense theological convictions and definite expectations about how seriously Christianity should be taken as the focus of human existence
