In 1643, one hundred and twenty-one Puritan clergymen met in Westminster Abbey for the purpose of drafting official documents that would serve to reform the Church of England. The Westminster Confession of Faith, an extended, systematic summary of Reformed doctrine, was one of these documents. The Confession still serves as one of the standard texts of the Church of Scotland, and it remains influential within Presbyterian churches across the world. This version of the Westminster Confession of Faith is that currently adopted by the Presbyterian Church in the United States (PCUS) and the United Presbyterian Church in the United States of America
