Once upon a time, two committed Christians opened the Bible to answer the same question that troubled them both: Does baptism merely symbolize salvation, or does it bring about new birth?

This question did not arise from idle curiosity. It reached far beyond academic speculation. It concerned salvation itself. With such high stakes, both men wanted more than a formed opinion—they wanted the truth. God’s truth.

Yet truth has a fixed nature. If these two men reached contradictory conclusions, both could not be right at the same time and in the same sense. Of the two, only one possessed the means to answer the question in a meaningful and definitive way.

Anthony, the first Christian, was a committed Protestant. He believed in the perspicuity of Scripture—that the Bible clearly teaches what is necessary for salvation:

those things which are necessary to be known, believed, and observed for salvation, are so clearly propounded, and opened in some place of Scripture or other, that not only the learned, but the unlearned, in a due use of the ordinary means, may attain unto a sufficient understanding of them. [emphasis added]

In other words, Anthony adhered to sola scriptura, Protestantism’s foundational doctrine.

“Surely,” he thought as he opened his New King James Version Bible, “God’s Word will clearly teach me—or correct me—regarding the true nature of baptism.”

Now consider Douglas. Unlike Anthony, Douglas was a committed and faithful Catholic. He trusted the Magisterium and believed that one must interpret Scripture within the Church.

“The Church has not left this unanswered,” Douglas thought. “I do not stand alone—I receive what has already been handed down.”

Anthony and Douglas shared much in common. Both loved Christ. Both believed the Bible was inspired by God. Both prayed for the guidance of the Holy Spirit when they read Scripture. They differed not in sincerity, but in their understanding of authority.

The difference between them would not lie in the text—but in who had the authority to say what it meant.

The Question: What Does Baptism Do?

The question before Anthony and Douglas concerned the nature of baptism. Some Christians view baptism as merely symbolic, an act of obedience to Christ’s command. Others—including Douglas—understand baptism as salvific: the moment when God imparts grace, forgives sins (both original and actual), and initiates the believer into the life of salvation.

Several key texts stood at the center of their inquiry:

John 3:5

Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.”

Acts 2:38

And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”

1 Peter 3:21

Baptism, which corresponds to this, now saves you—not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ.

Both men approached these passages with seriousness. They prayed, consulted study tools, and examined the witness of Christian history.

Anthony’s Journey: The Weight of Interpretation

After a period of careful study, Anthony finally reached a conclusion: baptism did not affect salvation—though it closely accompanied it in a secondary sense—but instead served as a sign and seal of the New Covenant. He further concluded that baptism, while sacramental, does not regenerate.

Anthony interpreted “water and Spirit” in John 3:5 in a spiritual or metaphorical sense. Likewise, in Acts 2:38, he saw baptism as closely tied to forgiveness but not its cause. Finally, he understood “baptism now saves you” in 1 Peter 3:21 as referring not to the physical act itself, but to the inward reality it signifies.

At first, Anthony felt intellectually justified. He saw coherence in his system, which preserved salvation by grace and the priority of faith. “Scripture speaks in a sacramental way,” he reasoned, “but it does not teach that water itself regenerates.”

Over time, however, he encountered pushback—not from Catholics like Douglas, but from other Protestants who used the same texts and methods. The earliest Protestants, the Lutherans, affirmed baptismal regeneration. Baptists, by contrast, denied it vigorously, while Anglicans held a range of positions. The same texts, the same methods—yet different conclusions.

This realization forced Anthony to pause. Why did others, using the same Bible and the same interpretive approach, arrive at different conclusions? Had they misread Scripture? Or had he? Should he revise his position, or stand firm?

Anthony remained confident, but he could not resolve the disagreement. He had reached a conclusion. What he had not found was a way to make it binding.

Douglas’s Journey: Receiving What Has Been Handed Down

At first, Douglas followed a path similar to Anthony’s. He approached the texts carefully and prayerfully. He consulted Scripture and reflected on its meaning. However, as a Catholic, he also considered how Christians before him had understood these passages. He read Scripture within the life of the Church.

In doing so, he discovered a consistent witness: the Church had long affirmed baptism not merely as a symbol, but as the means by which God grants new birth, forgives sins, and incorporates believers into Christ. This understanding did not arise from isolated interpretations, but from the Church’s continuous teaching through the Magisterium.

Douglas did not set aside the force of Scripture; he received it within that same tradition. The words “born of water and the Spirit,” “for the forgiveness of your sins,” and “baptism now saves you” did not stand alone as texts to be debated endlessly. The Church had already given them a definitive meaning.

This did not eliminate the need for study or reflection. Douglas still wrestled with Scripture, sought deeper understanding, and grew in his appreciation of its richness. But when questions arose, he did not face them alone.

Where Anthony encountered competing interpretations, Douglas encountered a settled teaching. Where Anthony had to decide, Douglas could receive.

“The Church has not left this unanswered,” he thought. “I do not stand alone—I receive what has already been handed down.”

Douglas, like Anthony, reached a conclusion. But unlike Anthony, he did not bear the weight of making it binding.

Two Ways of Knowing

Both Anthony and Douglas sought to know the truth about baptism by studying the Scriptures. However, their different sources of authority led them down divergent paths. Anthony, relying on sola scriptura, ultimately depended on his own interpretation to determine what Scripture teaches. Douglas, by contrast, received and submitted to what the Church teaches.

For Anthony, no final court of appeal exists. For Douglas, one does—the Church. For Anthony, unity depends on agreement with his conclusions, if such agreement can be found at all. For Douglas, unity rests on a shared authority that precedes individual interpretation.

Both read Scripture. Only one had a way to settle what it meant.

The Objection: “But Anthony Has Authorities Too”

Some on Anthony’s side will object: “But Anthony has authorities too. During his study of baptism, he consulted Church history, scholars, creeds, and pastors. He is not alone, nor is he careless.”

This is true—but with an important qualification.

Anthony accepts creeds only insofar as they align with his interpretation of Scripture. He respects the Church Fathers, but he regards them as corrigible. Confessions bind him only so long as he agrees with them. In each case, the pattern remains the same: every authority speaks—but only after Anthony permits it.

Yet an authority that must first be approved is not truly an authority—it is an educated opinion. Anthony must choose between competing authorities and judge which ones interpret Scripture correctly. In doing so, he places himself above them all.

Therefore, the final authority is not the expert, the creed, or history—but Anthony himself.

At This Point…

At this point, someone might object: “But your claim—that Christ established a Church with authority—is itself an interpretation of Scripture.”

That is true. But this does not solve the problem—it restates it.

The question is not whether interpretation is involved. Every Christian must interpret Scripture. The question is what happens when interpretations conflict.

When Anthony and Douglas disagree, both appeal to Scripture. Both claim fidelity to its meaning. Both offer interpretations. But which interpretation prevails—and why?

If no authority exists to resolve the dispute, then the disagreement remains permanent. If an authority does exist, then the question becomes whether Christ established it.

Interpretation is unavoidable. The real issue is whether it is finalized.

Final Thoughts… The Question That Remains

Anthony and Douglas began with the same Bible. They approached it with the same sincerity, the same desire for truth, and the same reliance on God’s guidance. Yet they arrived at different conclusions about a question that touches salvation itself.

The difference did not lie in the text.

It lay in who had the authority to say what the text means. Scripture does not interpret itself. Someone must read it, understand it, and determine its meaning. When disagreements arise—as they did for Anthony and countless others—an interpretation must prevail. But who decides which interpretation is correct?

So, the question remains:

When two sincere Christians disagree about what Scripture teaches regarding salvation—who has the authority to decide?

If the answer is “the individual,” then the final authority rests not in Scripture alone, but in the one who interprets it.

If the answer is something more—something visible, historical, and binding—then the question is no longer whether authority exists, but where Christ placed it.

…despite the undeniable influence of the church fathers (especially some aspects of the later Augustine) on the magisterial Protestant reformers, and notwithstanding their acceptance of early conciliar decrees, the magisterial reformers rejected patristic theological claims and interpretations of scripture, just as they rejected medieval exegesis, papal decrees, canon law, conciliar decrees, and ecclesiastical practices, precisely wherever any of these contradicted their own interpretations of the Bible. In no sense therefore was “tradition” for magisterial Protestant reformers an authority to which they deferred relative to their respective readings of scripture, as it was for their Catholic counterparts. This was the whole point and part of the power of “scripture alone.”

Neither magisterial nor radical Protestant reformers modified their hermeneutical judgments when these were at odds with traditional authorities; instead, they rejected the latter at each point of disagreement. – Brad Gregory, The Unintended Reformation: How a Religious Revolution Secularized Society
