The Westminster Assembly of Divines was a council of theologians and members of the English Parliament appointed to restructure the Church of England. It was formed in 1643 during the lead up to the First English Civil War by the Long Parliament.

This is a concise history, written by Benjamin Warfield, of The Assembly's work between the years 1643 up until sometime about 1660. From its efforts were 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 for the Churches of England and Scotland.
