Confessionalism Strengthens the Church’s Mission

One of the most persistent criticisms of confessional churches is that they become so concerned with doctrine that they neglect the church’s mission. According to this way of thinking, theological precision produces inward-looking churches where our confession becomes a barrier to evangelism and stalls the church’s command to make disciples.

For the true confessional church, that assumption is totally mistaken.

Consider how my own denomination, The Presbyterian Church in America, has summarized her identity for more than fifty years. We have three simple commitments: Faithful to the Scriptures, True to the Reformed Faith, and Obedient to the Great Commission.

Notice that those commitments are not presented as competing priorities. They belong together.

The denomination’s founders understood that doctrinal fidelity and evangelistic zeal are not enemies, but actual allies, that stregthen one another.

Before Jesus commanded His disciples to go into all the world, He declared, “All authority in heaven and on earth has been given to me.”

The Great Commission begins with doctrine. It begins with Christ’s authority. Everything that follows, like making disciples, baptizing, teaching, and planting churches, flows from who Christ is. The church’s mission, then, is never detached from theology. In fact, every missionary effort is built upon doctrinal convictions.

Consider some simple, yet profound, practical questions.

• Why proclaim Christ unless He is the only Savior?

• Why preach repentance unless mankind is truly fallen?

• Why plant churches unless Christ intends to gather His people into visible congregations?

• Why cross oceans unless the gospel is genuinely the power of God unto salvation?

The church’s mission is fueled by what she believes.

One of the great gifts of confessional theology is confidence.

Reformed theology reminds us that salvation belongs to the Lord. Christ is building His church, the Holy Spirit is effectually calling sinners through the ordinary ministry of the Word, and even though the gates of hell are raging, they will not prevail against Christ’s kingdom.

Those convictions do not diminish evangelism, but they absolutely sustain it. Missionaries can labor for decades because they believe God has His people among the nations. Pastors can preach faithfully Lord’s Day after Lord’s Day because they believe the Spirit works through the preached Word. Church planters can endure hardships because they believe Christ has promised to build His church.

Confessional theology gives ordinary Christians extraordinary confidence because the success of the mission ultimately rests upon God rather than human ingenuity.

Modern evangelicalism often measures success primarily by “decisions,” congregational size, or visible growth. Yet, Jesus commanded His disciples to make disciples. Christ even gives us the picture of what a disciple is; one who is baptized, taught, gathered into local churches, and learning to observe everything Christ commanded.

That vision requires healthy churches.

This is where confessionalism makes such a profound contribution.

The Westminster Standards provide churches with a mature theological framework for nurturing believers from conversion to maturity. They help churches answer questions that inevitably arise after someone comes to faith.

• What is the church?

• Why does worship matter?

• What are the sacraments?

• How does sanctification work?

• What is assurance?

• What is the Christian life supposed to look like?

Confessional churches are not simply concerned with getting people into heaven, though that’s an important first step, but they’re also concerned with growing people into mature disciples of Christ.

Like many denominations, the PCA faces constant pressure to redefine herself. Some encourage us to become more broadly evangelical. Others encourage us to become more culturally adaptive. Still others suggest that strong Presbyterian distinctives hinder outreach.

But every denomination eventually faces the same question. If we continually minimize our theological convictions in order to become more broadly acceptable, what exactly are we inviting people into?

The answer cannot simply be generic evangelicalism. The PCA has something worth offering, and we do! We have a high view of Scripture, a rich understanding of covenant theology, reverent worship, the ordinary means of grace, biblical church government, meaningful church membership., intentional discipleship, strong pastoral oversight, and healthy ecclesiology.

These are gifts to Christ’s church. People are not merely looking for churches with excellent branding. Increasingly, they are looking for churches with theological substance, historical rootedness, and spiritual stability.

Confessional Presbyterianism offers exactly that.

One of the greatest contributions confessionalism makes to missions is its vision for church planting. Church planting is not merely gathering a crowd; it is establishing a church. That distinction matters.

Healthy churches require qualified elders, faithful preaching, biblical worship, the right administration of the sacraments, church discipline, meaningful membership, careful discipleship, and connectional accountability.

In other words, church planting requires ecclesiology. Confessionalism supplies that ecclesiology.

Rather than viewing theology as something to add after numerical growth occurs, confessional churches recognize that sound doctrine should shape the church from its earliest days.

That foundation often produces slower growth, but it also produces stronger churches.

Perhaps the greatest irony is that many churches search for extraordinary methods to accomplish what Christ has already promised to accomplish through ordinary means.

We often assume the church needs newer strategies, all the while Christ repeatedly directs us back to the ministry He ordained.

The Word preached. The sacraments administered. Prayer offered. The saints gathered.

Those ordinary means have carried the gospel across continents for two thousand years, and remain sufficient today.

Confessional churches continue believing this because confessional theology teaches us to trust God’s appointed means more than our own creativity.

Throughout this series we have seen that confessionalism strengthens counseling, membership, officer training, educational ministries, and preaching.

Now we arrive at the church’s mission, and the conclusion remains exactly the same.

Confessionalism does not weaken the church’s witness, but strengthens it.

Healthy missions grow from healthy churches. Healthy churches grow through faithful preaching. Faithful preaching is rooted in sound doctrine. And sound doctrine produces mature disciples who are prepared to carry the gospel into their homes, communities, workplaces, and the nations.

Perhaps this is why the founders of the PCA wisely refused to choose between doctrinal fidelity and missionary zeal. They understood that the church’s greatest missionary strength would never come from abandoning her theological convictions, but wholeheartedly embracing them.

To be faithful to the Scriptures, true to the Reformed faith, and obedient to the Great Commission is not to pursue three different goals. It is to pursue one unified vision of Christ’s church…a church rooted so deeply in the truth that they then carry the gospel faithfully to the ends of the earth.
