Westminster Confession of Faith
The Westminster Confession of Faith is a Reformed confession of faith. Drawn up by the 1646 Westminster Assembly as part of the Westminster Standards to be a confession of the Church of England, it became and remains the "subordinate standard" of doctrine in the Church of Scotland, and has been influential within Presbyterian churches worldwide.
In 1643, the English Parliament called upon "learned, godly and judicious Divines", to meet at Westminster Abbey in order to provide advice on issues of worship, doctrine, government and discipline of the Church of England. Their meetings, over a period of five years, produced the confession of faith, as well as a Larger Catechism and a Shorter Catechism. For more than three centuries, various churches around the world have adopted the confession and the catechisms as their standards of doctrine, subordinate to the Bible.
The Westminster Confession of Faith was modified and adopted by Congregationalists in England in the form of the Savoy Declaration (1658). Likewise, the Baptists of England modified the Savoy Declaration to produce the Second London Baptist Confession (1689). English Presbyterians, Congregationalists, and Baptists would together (with others) come to be known as Nonconformists, because they did not conform to the Act of Uniformity (1662) establishing the Church of England as the only legally approved church, though they were in many ways united by their common confessions, built on the Westminster Confession.
During the English Civil War (1642–1649), the English Parliament raised armies in an alliance with the Covenanters who by then were the de facto government of Scotland, against the forces of Charles I, King of England, Scotland and Ireland. The purpose of the Westminster Assembly, in which 121 Puritan clergymen participated, was to provide official documents for the reformation of the Church of England. The Church of Scotland had recently overthrown the bishops imposed by the King and reinstated presbyterianism (see Bishops' Wars). For this reason, as a condition for entering into the alliance with the English Parliament, the Scottish Parliament formed the Solemn League and Covenant with the English Parliament, which meant that the Church of England would abandon episcopalianism and consistently adhere to Calvinistic standards of doctrine and worship. The Confession and Catechisms were produced in order to secure the help of the Scots against the king.
The Scottish Commissioners who were present at the Assembly were satisfied with the Confession of Faith, and in 1646, the document was sent to the English parliament to be ratified, and submitted to the General Assembly of the Scottish Kirk. The Church of Scotland adopted the document, without amendment, in 1647. In England, the House of Commons returned the document to the Assembly with the requirement to compile a list of proof texts from Scripture. After vigorous debate, the Confession was then in part adopted as the Articles of Christian Religion in 1648, by act of the English parliament, omitting section 4 of chapter 20 (Of Christian Liberty), sections 4–6 of chapter 24 (Of Marriage and Divorce), and chapters 30 and 31 (Of Church Censures and Of Synods and Councils). The next year, the Scottish parliament ratified the Confession without amendment.
In 1660, restoration of the British monarchy and Anglican episcopacy resulted in the nullification of these acts of the two parliaments. However, when William of Orange replaced the Roman Catholic King James VII of Scotland and II of England on the thrones of Scotland, England and Ireland, he gave royal assent to the Scottish parliament's ratification of the Confession, again without change, in 1690.
It includes doctrines common to most of Christendom such as the Trinity and Jesus' sacrificial death and resurrection, and it contains doctrines specific to Protestantism such as sola scriptura and sola fide. Its more controversial features include double predestination (held alongside freedom of choice), the covenant of works with Adam, the Puritan doctrine that assurance of salvation is not a necessary consequence of faith, a minimalist conception of worship, and a strict sabbatarianism.
Even more controversially, it states that the Pope is the Antichrist, that the Roman Catholic mass is a form of idolatry, that the civil magistrates have divine authority to punish heresy, and rules out marriage with non-Christians. These formulations were repudiated by several bodies which adopted the confession (for instance, the Church of Scotland, though its ministers are still free to adhere to the full confession and some do), but the confession remains part of the official doctrine of some other Presbyterian churches. For example, the Presbyterian Church of Australia holds to the Westminster Confession of Faith as its standard, subordinate to the Word of God, and read in the light of a declaratory statement.
American Presbyterian adoption and revisions
The first American Presbyterian ministers were New England Congregationalists, whose congregations originated with the migration from England to the Dutch colony in America as early as the 1640s, and Presbyterian immigrants from Scotland, Ireland and Wales. The first American presbytery, uniting some of these independent congregations and those of the British immigrants, was formed in 1706. This body grew large enough to form the first synod in Philadelphia in 1716. Prior to 1729, some presbyteries required candidates for the ministry to profess adherence to the Westminster Confession. When the Synod of Philadelphia met in 1729 to adopt the Westminster Confession as the doctrinal standard, it required all ministers to declare their approval of the Westminster Confession of Faith and catechisms. At the same time, the Adopting Act allowed candidates and ministers to scruple articles within the Confession. Whether or not the article scrupled was essential or nonessential was judged by the presbytery with jurisdiction over the candidate's examination. This allowance implied a difference, within the standards themselves, between things that are essential and necessary to the Christian faith, and things that are not. This compromise left a permanent legacy to following generations of Presbyterians in America, to decide what is meant by "essential and necessary", resulting in permanent controversies over the manner in which a minister is bound to accept the document; and it has left the American versions of the Westminster Confession more amenable to the will of the church to amend it.
When the Presbyterian Church in the United States of America was formed in 1788, it adopted the Westminster standards, as containing the system of doctrine taught in the Holy Scriptures. However, it revised chapters 20.4, 23.3, and 31.2 of the Confession, basically removing the civil magistrate (i.e., the state) from involvement in ecclesiastical matters. It also removed the phrase "tolerating a false religion" from the list of sins forbidden in Answer 109 of the Larger Catechism, and replaced "depopulations" in Answer 142 with "depredation." The Confession was amended again in 1887, when the final sentence of chapter 24.4, which forbade the marrying of the close kindred of one's deceased spouse, was removed.
The Presbyterian Church in the U.S.A. adopted more sweeping revisions of its Confession in 1903. Chapter 16.7, on the works of unregenerate men, was rewritten. The last sentence of chapter 22.3, which forbade the refusing of a proper oath when imposed by lawful authority, was removed. Chapter 25.6, on the head of the church, was rewritten, and the identification of the Roman Catholic pope as the Antichrist was removed.
