The Westminster Assembly met from 1643-1649 with a mandate to produce a doctrinal standard that would promote unity between the church in England and Scotland as well as Wales and Ireland. Amongst the numerous documents produced by the Assembly is the Westminster Confession of Faith. This is regarded by many theologians and historians to be one of the most, if not the most, theologically robust, comprehensive and biblical creed that Christendom has ever produced. It is the standard that undergirds most Presbyterian Churches throughout the world. Regrettably, though many Christians today are either unfamiliar with it or can only claim a superficial acquaintance with it. This commentary compiled out of class notes for a sabbath class in Pilgrim Covenant Church in Singapore is designed to give a fairly in-depth introduction to this historic creed to stir an interest to study it and also to encourage its honest use to bring the church back to the Old Paths wherein Christ may be highly exalted through faith and obedience in Him.
