This painting by John Rogers Herbert depicts a particularly controversial speech before the Assembly by Philip Nye against presbyterian church government.

The Westminster Assembly of Divines was a council of theologians (or "divines") and members of the English Parliament appointed to restructure the Church of England which met from 1643 to 1653. 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.
