Yesterday’s post described the mechanism, the four-stage process by which the confession gradually, invisibly displaces the Word as the governing authority in a community that genuinely intends to honor Sola Scriptura. The most common response from people inside those communities is: “But that’s not us. We hold the confession as a faithful summary of Scripture. We would revise it if the text required. We apply the Berean test.”
They may be right. Some confessional communities do hold the confession as a servant of the Word. Some do apply the Berean test to their own confessional conclusions. Not every confessional community has reached Stage Four. But the only way to know which stage a community is at is to apply diagnostic tests. Not the community’s self-description, self-description is unreliable, because every community at every stage describes itself as holding the Scripture as the supreme authority. The tests that reveal the functional reality, not the formal declaration.
“Examine yourselves, whether ye be in the faith; prove your own selves” (2 Corinthians 13:5). Examine. Prove. The call to honest self-examination, not the comfortable assurance that everything is as it should be, but the honest application of the diagnostic that reveals whether the reality matches the declaration. Today, five diagnostic tests.
Test One: The Revision Test
The question: Is there any position your community currently holds, any doctrine formally stated in the confession or catechism that governs your community, that you would be genuinely willing to revise if the plain text of Scripture, honestly and carefully read, required it?
Not: is there any doctrine you have already revised. Not: are there any doctrines that are formally under review. The question is whether the possibility exists, whether the community has a functional mechanism for confessional revision when the Word requires it.
A community at Stage One can answer yes easily. The confession is a servant. The text governs. Revision is possible, even expected when careful reading requires it.
A community at Stage Four finds the question almost meaningless. What would it mean to revise the Westminster Confession? The confession is the standard. The text is read through it. A reading that differs from the confession is not a candidate for revision, it is an error to be corrected.
Apply this test carefully: not do you think the confession might be wrong about something? but if you concluded it was wrong about something through careful exegetical work, what would happen? Would the community engage the exegetical argument? Or would the community invoke the confessional standard as the terminal response?
Test Two: The Elder Test
The question: What happens when a trained biblical scholar, an ordained elder or pastor in your community, arrives, through careful, honest, sustained exegetical work, at a conclusion that differs from the Westminster Confession’s formulation of the same doctrine?
The Berean response: let us examine the text together. Let us evaluate whether the confession has accurately represented what the text says. Let us bring the exegetical argument to the community’s honest engagement with the Word.
The Sola Confessio response: this reading falls outside the bounds of our confessional standards. The ordained officer who holds this position will be required to revise it, suppress it, or face ecclesiastical discipline.
The specific diagnostic value of the elder test is that it involves the community’s most trained and most trusted textual interpreters. If even the trained elder’s careful exegetical work cannot dislodge a confessional conclusion, if the response to the trained exegete who differs from the confession is discipline rather than dialogue, the confession has unambiguously moved from servant to master.
In how many confessional communities does a pastor’s honest exegetical departure from the Westminster Confession result in formal discipline? The answer to that question reveals whether the community is practicing Sola Scriptura or Sola Confessio.
Test Three: The Heresy Test
The question: Is the charge of heresy available to be leveled in your community against someone whose reading of a biblical text departs from the confessional standard, without reference to whether the biblical text actually supports the confessional conclusion?
Heresy is a serious charge. It names a position as so far outside the bounds of genuine Christian faith that it constitutes apostasy, a departure from the faith itself. The charge is legitimate when a reading of the Scripture contradicts what the Scripture clearly teaches about the nature of God, the person of Christ, the necessity of salvation through the atoning work of Christ.
But heresy is being misused when it is deployed against a reading that differs from the confessional tradition’s formulation without any examination of whether the confessional tradition has accurately represented the relevant Scripture. When “this is outside our confessional standards” and “this is heresy” become functionally equivalent charges, when confessional departure and doctrinal error are treated as the same thing, the confession has claimed an authority over faith that belongs only to the Scripture.
The heresy test: if someone in your community departed from the Westminster Confession’s formulation of a specific doctrine and offered careful exegetical grounds for the departure, would the community distinguish between “the confession has settled this” and “the Scripture has settled this”? Or would those two claims be treated as equivalent?
Test Four: The Imagination Test
The question: Can your community genuinely imagine that a careful, Spirit-filled, honest reading of a biblical text might produce a conclusion that differs from the confessional tradition’s formulation, and hold that possibility as a genuine possibility rather than an obvious error?
This is the most subtle test. It does not require an actual departure. It requires only the capacity to hold the possibility. The Berean congregation could not have practiced Acts 17:11 if they could not genuinely imagine that Paul might have been wrong about something. The willingness to test implies the possibility that the test might reveal something unexpected.
The community at Stage One can hold the imagination test easily. Of course the confession might have erred. It is a human document. Careful reading of the text might reveal that error. The possibility is genuinely open.
The community at Stage Four finds the imagination test nearly impossible. The confession’s formulations are not merely confident theological positions, they have become the definition of what a sound reading of the relevant texts looks like. A reading that differs from the confession is not merely wrong, it is unimaginable as the product of a careful, Spirit-led, honest engagement with the text.
This closing of the theological imagination is perhaps the most significant single symptom of Stage Four confessionalism. Not the formal declaration that the confession is infallible, the functional inability to imagine that it might have erred.
Test Five: The Formation Test
The question: In the theological formation your community provides, the seminary, the catechism classes, the preaching, the small group curriculum, is the student being formed in the Word itself, or in the Word as the confession has interpreted it?
The formation test reveals the community’s generational investment. How are the next generation of leaders and believers being trained? Through the Word, equipped to read the Scripture directly, test interpretations against the text, hold the confession as a useful tool and the Word as the governing standard? Or through the confession, receiving the confessional conclusions first and then learning to read the Scripture in the ways that confirm those conclusions?
The specific diagnostic: when a seminarian encounters a biblical text that creates tension with the confessional tradition, what are they taught to do with that tension? Are they taught to engage the tension honestly, to bring the text and the tradition into genuine dialogue, test the tradition against the text, and follow the text wherever it leads? Or are they taught to resolve the tension by finding the reading of the text that fits the confessional conclusion, to interpret the apparent tension away rather than engage it honestly?
The community that forms its next generation to resolve tensions in favor of the confession has institutionalized Stage Four. The community that forms its next generation to engage tensions honestly, bringing them to the text rather than to the tradition, is practicing genuine Sola Scriptura.
Applying the Tests
These five tests are not designed to be applied in a spirit of accusation or to produce condemnation of confessional communities. They are designed to produce honest self-examination, the examine yourselves that 2 Corinthians 13:5 calls every community to.
Many confessional communities will discover, on honest application of these tests, that they are at Stage Two or Stage Three, not yet at Stage Four, but moving in the direction that Stage Four represents. That discovery is not a condemnation. It is a call. The semper of semper reformanda, always reforming, is available to communities at Stage Two and Stage Three. The return to Stage One is always possible when the community is willing to hear it.
The community that applies these tests honestly and discovers it has reached Stage Four is not a failed community. It is a community that has made the error the Reformation corrected, the same error Rome made, with different materials. And the same recovery is available: the Word above the tradition, the confession as servant rather than master, the Berean test applied to every claim including the confessional ones.
The tests are the invitation to that recovery.
Tomorrow, Day 13, where the mechanism is most visible. The specific patterns in specific communities.
