The Westminster Confession of Faith was the work of the Assembly of divines which was called together by Parliament and met in London, at Westminster Abbey, during the years 1643-1648. It was this Assembly which also produced the Larger and Shorter Catechisms. The Confession and the Catechisms are used by many churches as their doctrinal standards, subordinate to the Word of God.
The text of the confession as given on the above links is in the form adopted by the Orthodox Presbyterian Church (USA) and the Reformed Churches of New Zealand, and except for a few revisions, which are largely concerned with the relation of the civil magistrate to the church, it agrees with the text of the original manuscript of the confession.
The Westminster Confession has been accepted by the Reformed Churches of Australia in 1957 as the fourth Confessional Standard, with the understanding that on those points where the Westminster Confession goes further than the Belgic Confession the office bearers and members of the churches will be bound to the latter only.
