The Westminster Confession of Faith is a Reformed confession of faith in the Calvinist theological tradition. Although drawn up by the 1646 Westminster Assembly, largely of the Church of England, it became the 'subordinate standard' of doctrine in the Church of Scotland and has been influential within Presbyterian churches worldwide. With selected changes it has also been adopted by some Congregationalists and was the basis for the 1689 London Baptist Confession.
The 1789 American Revision
The revisions of 1787-1789 removed certain powers of the civil government over the church, which might be called theocratic principles, from the Westminster Confession of faith and catechisms. It also removes explicit identification of the Pope as the Antichrist.
The Westminster Standards are the Westminster Confession of Faith, the Westminster Shorter Catechism, the Westminster Larger Catechism, the Directory of Public Worship, and the Form of Church Government referred to collectively.
