In 1643, during a time of political turmoil, military conflict and threats to religious freedom, the English Parliament called upon 121 "learned, Godly and judicious" pastors, teachers and Theologians, to meet at Westminster Abby to provide considered guidance on issues of Faith and conduct, doctrine and devotion, applying the Lordship of Christ to all areas of life.
The Westminster Assembly produced what has been described as the finest, most Biblical description and definition of Christian life, faith and practise. The Westminster Confession, The Larger Catechism and The Shorter Catechism, have been adopted as the standards for most Reformed Churches.
The Westminster Confession was adopted by Act of the English Parliament in 1648 and by the Scottish Parliament in 1649.
The Westminster Standards have been adopted, with minor modifications, by the Congregational Churches in the form of The Savoy Declaration (1658), by the Baptists, in the London Confession of Faith (1689), and others.
