One of the most influential creeds of Calvinism, a creedal standard for all Presbyterian churches, drawn up at Westminster (1643-46). The immediate background to the Confession lies in the tensions between Charles I* and his subjects, growing in large measure out of Charles's insistence on imposing Anglicanism. In an age when it seemed obvious that the state, concerned with the welfare of its citizens, was hence concerned with religious affairs, such a stance had political implications. The Puritans* felt that the creeds of the [[Church of England]]* must be revised, so that a pure religion would be taught and preached. The Scots, convinced Calvinists, resisted any attempt to remodel their creeds. In 1638 the historic [[National Covenant]]* affirmed this, and a Scots invasion of N England forced Charles to call Parliament into session. But it demanded far-reaching concessions from Charles which he refused, and by 1642 civil war had broken out.
