The Westminster Confession on Scripture: Why the Bible Is the Church’s Only Rule

The Westminster Confession begins with Scripture because everything else depends on it. Before the Assembly could say what Christians believe about God, creation, redemption, or the church, it had to establish why these beliefs are trustworthy and where they come from. Chapter 1 — 'Of the Holy Scripture' — is the foundation on which the Confession's entire structure rests.

The Necessity of Scripture

Section 1 opens by acknowledging that God has revealed Himself through creation and providence — what theologians call general revelation. But this natural knowledge is insufficient for salvation. 'Therefore it pleased the Lord, at sundry times, and in divers manners, to reveal Himself, and to declare that His will unto His Church; and afterwards for the better preserving and propagating of the truth, and for the more sure establishment and comfort of the Church against the corruption of the flesh, and the malice of Satan and of the world, to commit the same wholly unto writing.'

Authority and Inspiration

The Confession affirms that Scripture's authority rests not on the testimony of any man or church but 'wholly upon God (who is truth itself) the author thereof.' The 66 books of the Old and New Testament are listed explicitly as Holy Scripture. Their authority is grounded in the fact that they are 'given by inspiration of God' — a direct affirmation of what the Confession calls the 'inward work of the Holy Spirit' bearing witness in and by the Word.

The Supreme Judge

Section 10 is perhaps the most famous sentence in the entire Confession: 'The supreme judge by which all controversies of religion are to be determined, and all decrees of councils, opinions of ancient writers, doctrines of men, and private spirits, are to be examined, and in whose sentence we are to rest, can be no other but the Holy Spirit speaking in the Scripture.' This is sola Scriptura stated with maximum precision: not Scripture alone as interpreted by the individual, nor Scripture as filtered through church authority, but Scripture as illumined by the Spirit who inspired it.
