By establishing broader assemblies of elders with real, but fallible and strictly spiritual authority, the Confession provides a system designed to protect the flock, maintain the truth, and preserve the peace of Christ’s kingdom.

In the previous chapter, we saw that Christ has appointed a government for His Church, placed in the hands of church officers. But how far does that government extend? Does a local congregation operate entirely on its own, completely independent of all other churches? Or is it part of a broader, connected body?

In Chapter 31, the Westminster Confession articulates the Presbyterian form of church government. The word “Presbyterian” simply comes from the Greek word for “elder” (presbuteros). But crucially, Presbyterianism is not just about having a plurality of elders in a single local church; it is about the interconnectedness of those elders across multiple churches.

The Confession teaches that for the edification of the Church, there ought to be regional and broader assemblies (synods and councils); that these assemblies have real, ministerial authority to settle controversies and receive appeals; that they are fallible and therefore not the ultimate rule of faith; and that they must restrict themselves to ecclesiastical matters, never usurping the power of the civil state.

The Necessity of Broader Assemblies (WCF 31.1–31.2)

The Confession begins with a simple, foundational statement: “For the better government, and further edification of the Church, there ought to be such assemblies as are commonly called Synods or Councils.”

Why? Because the church is one body. When a major theological controversy arises, or when a local Session acts tyrannically, a single congregation cannot solve the problem alone. The biblical model for this is found in Acts 15 (the Jerusalem Council). When a massive dispute broke out in Antioch regarding circumcision, the local church did not just figure it out themselves. They sent Paul and Barnabas to Jerusalem to meet with “the apostles and elders” to debate the issue and issue a binding decree for all the churches.

(Note on WCF 31.2: As we saw in Chapter 23, the original 1646 text allowed the civil magistrate to call these synods. The 1788 American revision removed this power from the state entirely. In the American version, church officers assemble “of themselves, by virtue of their office,” completely independent of the government’s permission or summons.)

Ministerial Authority and Appeals (WCF 31.3)

When a Presbytery or General Assembly meets, what kind of authority do they have? Are they just an advisory board offering helpful suggestions? No. The Confession states that these councils have authority “ministerially to determine controversies of faith, and cases of conscience.”

Their authority is ministerial—meaning they do not invent new laws, but simply declare and apply the laws already found in God’s Word. But it is real authority. They are empowered to:

• Settle Controversies: Resolve theological disputes that threaten the peace and purity of the church.
• Order Public Worship: Set down rules for government and the right administration of worship.
