☩ Ecclesiology & Worship

Overview

WCF XXV–XXXI plus XXI handle the church (XXV), the communion of saints (XXVI), the sacraments (XXVII), baptism (XXVIII), the Lord's Supper (XXIX), church censures (XXX), synods and councils (XXXI), and religious worship (XXI). The Form of Presbyterial Church Government (1645) and the Directory for Public Worship (1645) supply the ordering detail. The Confession's polity is presbyterian *jure divino* in the Scottish reading (Rutherford, Gillespie) and *jure ecclesiastico* in the more cautious English reading; both held that the visible church is governed by officers (pastors, teachers, ruling elders, deacons) and by graded assemblies (session, presbytery, synod, general assembly). The sacramental theology is signs-and-seals: the sacraments 'really exhibit, as well as represent, the graces signified' (XXVII.1, XXVIII.6) — neither the Roman *ex opere operato* nor the Zwinglian bare memorial.

Philosophical significance

The Westminster ecclesiology is the most carefully argued Reformed polity of the seventeenth century. It is not merely a procedural church order but a constitutional theory of ecclesial sovereignty: Christ alone is head; the civil magistrate has duties around the church but no authority within it (XXX.1, XXXI.1–5; cf. the original XXIII.3 rejected in 1788 American adoption). The regulative principle of worship (XXI.1) — that worship is limited by God's own revelation in Scripture and not by human imagination or church tradition — is a determinate epistemology of worship as well as a polemic against the ceremonial and sacramental Catholicism the Assembly displaced.

Scriptural ground

Polity: Matthew 16:19; 18:17–20; Acts 6, 15, 20:17–28; 1 Timothy 3 and 5; Titus 1; Hebrews 13:7, 17. Sacraments: Romans 4:11; 1 Corinthians 10:16–21; 11:23–29; Matthew 28:19–20; Acts 2:38–39. Worship: Deuteronomy 12:32; Matthew 15:9; Colossians 2:23; John 4:23–24. Synods: Acts 15:1–35.

Key controversies

• Presbyterian vs Independent — The Five Dissenting Brethren (Goodwin, Nye, Bridge, Burroughs, Simpson) argued the congregational case in *An Apologeticall Narration* (1644); Rutherford, Gillespie, and the Scottish commissioners pressed presbyterianism. The Standards' polity is broadly presbyterian, but WCF XXX–XXXI is general enough that 1689 Particular Baptists and post-Savoy Congregationalists could adopt most of the language without contradiction. The decisive Assembly votes (1646) went with the presbyterian majority; the Independents protested but stayed.
• Erastianism — John Selden, John Lightfoot, and Thomas Coleman argued at Westminster for the Erastian position: ecclesiastical jurisdiction belongs ultimately to the civil magistrate, not to a distinct ecclesial court. Gillespie's *Aaron's Rod Blossoming* (1646) is the canonical refutation. WCF XXX.1 settled the matter: 'The Lord Jesus, as King and Head of his Church, hath therein appointed a government, in the hand of Church officers, distinct from the civil magistrate.'
• The regulative principle — WCF XXI.1: 'The acceptable way of worshipping the true God is instituted by himself, and so limited by his own revealed will, that he may not be worshipped according to the imaginations and devices of men…or any other way not prescribed in the Holy Scripture.' This is the strict (prescriptive) reading — only what is commanded may be done. The contrast is the Anglican-Lutheran *normative* principle: whatever is not forbidden may be done.
