Semper Reformanda

We now come to Semper Reformanda. Although it is not one of the five solas, it is a Reformation teaching that helps tie them all together. Over the last seven weeks, we traced the ecclesiological history of the medieval church, the need for the Reformation, and the development of the five solas—Scripture alone, grace alone, faith alone, Christ alone, and for the glory of God alone. Together, these reveal how salvation is found in Christ and how the Reformation sought to recapture the gospel.

The Origin and Meaning of Semper Reformanda

The phrase Semper Reformanda comes from the 17th century, first appearing in a Dutch minister’s devotional. The full Latin expression is Ecclesia Reformata, Semper Reformanda—“the church reformed, always being reformed.” In modern usage, you may also see Fides Reformata, Semper Reformanda—“the Reformed faith, always reforming.” Both emphasize the same idea: continual reformation.

Reformation, by definition, is the act of improving or correcting something—behavior, institutions, or practices—by removing abuses or corruptions. In a biblical sense, reformation aims to restore the church as closely as possible to its original, scriptural state. This is not a call to constant novelty or progressivism. Rather, it is a call to continually evaluate all we say, do, and believe according to Scripture.

When we consider the 15th and 16th centuries, it is important to remember that the Reformers did not set out to break from Rome. Luther did not intend to start a new church or create Lutheranism. His 95 Theses were written to correct errors in the church according to Scripture. He remained a Catholic monk and Augustinian until he was pushed out.

The Reformation began as a call to reform the church so that the Catholic Church—the “one true church” in their understanding—would once again be holy and faithful to Scripture. Every generation, however, tends to drift from the gospel. Scripture warns that people will seek teachers who “tickle their ears,” and this has been true in every age. Semper Reformanda calls us to examine whether we are following Scripture or merely following tradition.

Biblical Foundations for Semper Reformanda

Two key passages illustrate this principle:

Acts 17 — The Bereans

The Bereans “received the word with eagerness, examining the Scriptures daily to see if these things were so.” They did not simply accept Paul’s teaching because of his authority. They tested it against Scripture. This is a model for the church today: do not accept teaching merely because a pastor or leader says it. Pastors are fallible. Scripture alone is infallible.

1 Thessalonians 5:19–22 — Test Everything

Paul instructs the Thessalonians to “test everything; hold fast what is good.” This includes testing prophecies, teachings, and practices. The church must remain engaged, discerning whether teachings align with Scripture rather than being carried away by every new doctrine or personality.

Semper Reformanda is therefore a call to an active, thoughtful, Scripture-centered faith.

Common Errors 

A. Reformation as Nostalgic Renewal

Some interpret reformation as returning to an idealized past—whether medieval Catholicism, early church asceticism, or Puritanism. Each generation tends to romanticize a previous era. But no era of church history was perfect. Every age had blind spots, including our own.

The Reformers did look back to the early church and the original languages (ad fontes), but they did so to better understand Scripture—not to canonize past traditions or personalities.

B. Reformation as Endless Progressivism

Others believe “always reforming” means “always changing.” This leads to churches conforming to cultural trends—affirming whatever society affirms in the name of love or inclusion. This is not biblical reformation; it is capitulation.

C. Reformation as Endless Purification

On the opposite extreme, some pursue a “pure church” through constant division. John Frame famously called this phenomenon “Machen’s Warrior Children”—those who inherited Machen’s zeal for doctrinal purity but turned it into perpetual warfare. This leads to fragmentation, where every disagreement becomes grounds for separation. Erasmus warned Luther that schism breeds more schism, and history has proven him right.

Every generation faces new distortions of biblical truth:

  • Grace alone can become hyper-grace, denying repentance or holiness.

  • Faith alone can be subtly replaced with faith plus works or faith plus doctrinal precision.

  • Christ alone can become Christ plus tradition, Christ plus sacraments, or Christ plus theological systems.

  • Scripture alone can be overshadowed by favorite theologians, denominations, or cultural assumptions.

Semper Reformanda calls us to continually evaluate whether our beliefs and practices align with Scripture—not with tradition, culture, or personal preference.

Reformed theology holds two commitments:

  1. Reformed — Scripture is the foundation of all doctrine and practice.

  2. Reforming — We continually examine ourselves to ensure we remain faithful to Scripture.

This protects the church from:

  • Traditionalism (doing things because “we’ve always done it this way”)

  • Cultural accommodation (doing things because “the world says we should”)

Instead, we pursue a thoughtful, Scripture-driven faith that seeks to honor God in all things.

Conclusion

Semper Reformanda reminds us that the church must never drift into complacency. We must not coast or slide into neutral. Instead, we actively seek the Spirit’s guidance through the Word, allowing Scripture to teach, correct, admonish, and transform us.

That is the heart of Semper Reformanda.
