These developments show both the wide influence of Puritanism at the time and the different ways Puritans responded to royal authority: some, such as William Perkins, Master of Emmanuel College, worked within the established church; others, such as William Ames, left England and spent much of their careers in places like Holland. The English Puritan movement, which had started under Elizabeth and grew under James, sought to push the Reformation in the Church of England further, to remove all remaining Roman Catholic influence, and to promote the interests of the English crown and people under a united Protestant confession that followed the Bible and Reformed theology closely. This Puritan vision, developed in the Elizabethan and Jacobean periods, would later lead to the Westminster Assembly and the Westminster Standards, including the Westminster Confession of Faith, the Shorter Catechism, the Larger Catechism, and the Directory for Public Worship. Under James I of England, the Puritan movement and the conforming Church of England lived side by side within a generally accepted system of episcopal Protestant religion.
