The True Church: What the Belgic Confession Teaches About the Church

What is the true church? And how do you recognize it? These were urgent questions in sixteenth-century Europe, where the Reformation had broken the institutional unity of Western Christianity and thousands of believers faced persecution for leaving the Roman church. The Belgic Confession answered these questions with careful theological precision in Articles 27 through 32.

The Catholic Church

Article 27 begins by affirming belief in one holy, catholic Church. This is not the Roman Catholic Church as an institution but the universal company of true believers in Jesus Christ across all times and places. The Belgic Confession insists that this Church "has been from the beginning of the world and will be to the end thereof" — it existed before Rome, it continued through the medieval period, and it was not created by the Reformation.

The Three Marks of the True Church

Article 29 provides the Belgic Confession's famous definition of the true church by its three marks: (1) the pure preaching of the gospel; (2) the pure administration of the sacraments as Christ instituted them; and (3) the exercise of church discipline to correct faults and punish sinners. These marks have become the classic Reformed test for any church's legitimacy — not its history, hierarchy, or apostolic succession, but the faithfulness of its Word and sacraments.

The Obligation to Join the True Church

Article 28 makes a strong and often overlooked claim: believers are obligated to join themselves to the true church, wherever God has established it. No one may withdraw from the congregation and "content himself" with private faith. The church is not optional for the Christian. This was a pointed response to the Anabaptists, who often rejected visible church structures, and it remains a challenge to individualistic Christianity today.

Church Government and Discipline

Articles 30 through 32 address the government and discipline of the church. The confession affirms a form of church government by elders, deacons, and ministers — what became the Presbyterian and Reformed polity. Church discipline is to be exercised with gentleness and care, following the rule of Christ in Scripture. Ministers are to be called and ordained by the church; no one may appoint himself.

The Belgic Confession's ecclesiology is both high and practical. The church matters — enormously — but its authority derives entirely from Christ speaking through His Word. Where that Word is faithfully preached and the sacraments rightly administered, there is the true church of Jesus Christ, regardless of its institutional heritage or worldly standing. For a contemporary commentary applying the Belgic Confession to the modern church, Janssen's work offers a fresh and faithful engagement.
