The Westminster Assembly of Divines was a council of divines (theologians) and members of the English Parliament appointed from 1643 to 1653 to restructure the Church of England. Several Scots also attended, and the Assembly's work was adopted by the Church of Scotland. As many as 121 ministers were called to the Assembly, with nineteen others added later to replace those who did not attend or could no longer attend. It produced a new Form of Church Government, a Confession of Faith or statement of belief, two catechisms or manuals for religious instruction (Shorter and Larger), and a liturgical manual, the Directory for Public Worship, for the Churches of England and Scotland. The Confession and catechisms were adopted as doctrinal standards in the Church of Scotland and other Presbyterian churches, where they remain normative. Amended versions of the Confession were also adopted in Congregational and Baptist churches in England and New England in the seventeenth and eighteenth centuries. The Confession became influential throughout the English-speaking world, but especially in American Protestant theology.
The Assembly was called by the Long Parliament before and during the beginning of the First English Civil War. The Long Parliament was influenced by Puritanism, a religious movement which sought further reform of the church. They were opposed to the religious policies of King Charles I and William Laud, Archbishop of Canterbury. As part of a military alliance with Scotland, Parliament agreed that the outcome of the Assembly would bring the English Church into closer conformity with the Church of Scotland. The Scottish Church was governed by a system of elected assemblies of elders called presbyterianism, rather than rule by bishops, called episcopalianism, which was used in the English church. Scottish commissioners attended and advised the Assembly as part of the agreement. Disagreements over church government caused open division in the Assembly, despite attempts to maintain unity. The party of divines who favoured presbyterianism was in the majority, but the congregationalist party, which held greater influence in the military, favoured autonomy for individual congregations rather than the subjection of congregations to regional and national assemblies entailed in presbyterianism. Parliament eventually adopted a presbyterian form of government but lacked the power to implement it. During the Restoration of the monarchy in 1660, all of the documents of the Assembly were repudiated and episcopal church government was reinstated in England.
