Five days of personal testimony. Today the doctrine begins. And the doctrine needs to begin with a clarification, because Sola Scriptura is one of the most consistently misrepresented positions in the entire history of Christian theology. Its critics within Roman Catholicism misrepresent it. Its critics within Eastern Orthodoxy misrepresent it. Its critics within the charismatic world misrepresent it. And, this matters and will matter more as this series progresses, some of its self-professed defenders within Protestant confessionalism misrepresent it too.
If you define a position by how its critics describe it, you will never understand the position. And if you understand the position, you will immediately see why most of the standard objections miss it entirely. So before this series defends Sola Scriptura, let the doctrine speak for itself.
What Sola Scriptura Is NOT
Sola Scriptura is not the claim that the Bible is the only source of knowledge.
This is the most common caricature, that the Sola Scriptura Christian claims to derive all their knowledge from the Bible alone, that they deny natural revelation, that they refuse to learn from history, philosophy, science, or the accumulated wisdom of the church across twenty centuries.
Nobody who actually holds Sola Scriptura believes this. The Reformers read patristic theology voraciously. Calvin’s Institutes is saturated with Augustine. Luther was shaped by the medieval tradition he was critiquing. The Sola Scriptura position has never claimed that the Bible is the only source of any knowledge. What it claims is something far more specific.
Sola Scriptura is not the claim that tradition is worthless.
The Reformers did not reject tradition. They evaluated tradition, against the standard of Scripture. Creeds that accurately summarized biblical teaching were valuable to them. The Nicene Creed, the Chalcedonian definition of Christ’s two natures, these were treasured precisely because they were accurate distillations of what Scripture teaches.
The Reformation objection was not that tradition exists. It was that tradition had been elevated to a position of co-equal authority with Scripture, and that when tradition and Scripture conflicted, the church had chosen tradition. That is the specific error Sola Scriptura addresses.
Sola Scriptura is not the claim that every individual reads the Bible in isolation from the community.
The caricature here, sometimes called the solo scriptura error to distinguish it from genuine Sola Scriptura, is the idea that each believer, with their private Bible and their private judgment, is their own autonomous theological authority. That no one’s interpretation can be challenged. That the individual reading is as valid as the church’s historical reading. This is not Sola Scriptura. This is anarchy. And it is not what the Reformers held.
The Reformers affirmed the importance of community, of trained teachers, of the accumulated wisdom of faithful exposition across the centuries. What they denied was that any of these human authorities, however learned, however ancient, however beloved, could override the plain meaning of the Scripture they were interpreting. The community reads Scripture together. The individual reads within the community. But the Scripture, not the community, is the final court of appeal.
What Sola Scriptura Actually IS
With the misrepresentations cleared away, the positive definition. Sola Scriptura is the claim that the sixty-six canonical books of the Bible are the supreme, final, and infallible authority in all matters of Christian faith and practice.
Not the only authority. The supreme authority. The final authority. The authority against which every other authority, tradition, creed, confession, council, bishop, apostle, prophet, or pastor, is tested and to which every other authority is accountable. Let each word carry its weight.
Supreme. No other authority stands above it. No pope. No magisterium. No apostolic council. No confessional standard. No denominational tradition. In the hierarchy of authorities that governs the Christian’s understanding of faith and practice, the Scripture stands at the top. Everything else stands beneath it.
Final. When there is a dispute about Christian faith or practice, when tradition says one thing and the biblical text says another, the text is the final court of appeal. The dispute does not end when the council has spoken, or when the confession has ruled, or when the apostle has declared. It ends when the Scripture has been rightly understood. The Scripture, properly interpreted, is the final word.
Infallible. The Scripture does not err in what it affirms. The human teachers who interpret it do err, and will, consistently and predictably. The councils that formulate doctrine do err, the Reformers were willing to say so about the Council of Trent, and they were right. The confessions that systematize biblical teaching do err, even the best of them, the Westminster Confession, the Heidelberg Catechism, the Three Forms of Unity, contain formulations that require correction by the more careful reading of the text they were based on. But the Scripture itself, in what it actually affirms, does not err.
In all matters of Christian faith and practice. The authority of Scripture is not limited to some domain of spiritual or theological concern that is separate from the ordinary questions of life. It speaks to everything that bears on how a person stands before God and how they live in the world. It does not speak to every question, Deuteronomy 29:29 distinguishes the revealed things from the secret things, but what it does speak to, it speaks to with finality.
The Crucial Passage
The locus classicus for Sola Scriptura, the text to which every defence of the doctrine returns, is 2 Timothy 3:16-17: “All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be throughly furnished unto all good works.” Every word matters.
All scripture. Not some Scripture. Not the Scripture as interpreted by the Magisterium. Not the Scripture as clarified by ongoing prophetic revelation. All Scripture, the whole of the canonical text.
Given by inspiration of God. The Greek word translated inspiration is theopneustos, God-breathed. The Scripture did not originate in the minds of the human authors who wrote it. It was breathed out by God, the specific words were the product of the Spirit’s superintendence of the writing process, guaranteeing that what was written was what God intended to say.
Profitable for doctrine, for reproof, for correction, for instruction in righteousness. Four categories of usefulness, covering the full range of the believer’s theological and moral life. Doctrine; what to believe. Reproof; identification of what is wrong. Correction; restoration to what is right. Instruction in righteousness; formation in the pattern of life that God requires. The Scripture is the sufficient tool for all of these.
That the man of God may be throughly furnished unto all good works. Thoroughly; completely, fully, furnished. Equipped, for every good work the Christian life requires. Not partially equipped, pending supplementation by ongoing apostolic revelation or confessional tradition. Thoroughly, completely, already.
This is the Sola Scriptura claim in one verse. The Scripture, as given, is the sufficient tool for every theological and moral need of the genuine believer. It does not need the NAR’s prophetic supplements. It does not need Rome’s Magisterial interpretation. It does not need the Westminster Assembly’s systematization to become authoritative, it is already authoritative, and the Westminster Assembly’s value was in accurately summarizing what was already there.
The Role of Everything Else
If Scripture is the supreme and final authority, what is the role of creeds, confessions, councils, and tradition? They are useful. They are sometimes very useful. The Westminster Confession is a careful and largely faithful systematization of Reformed biblical theology. The Heidelberg Catechism is a devotionally rich and theologically sound instrument of Christian formation.
But, and this is the Sola Scriptura claim in its sharpest form, they are all fallible. Every one of them. Without exception.
Not because they are worthless. Because they are human. Because they were written by men who, however learned and however Spirit-guided in their work, were capable of error. Because no human being or human council has ever been given the kind of superintending Spirit-inspiration that guaranteed the original authors of Scripture against error.
Which means: every creed, every confession, every council decree, every pastoral declaration, every denominational standard, sits under the Scripture, not alongside it or above it. It is evaluated by the Scripture. Corrected by the Scripture when it departs from the Scripture. Honored when it accurately reflects the Scripture. Rejected when it contradicts the Scripture.
This is not the dismissal of tradition. It is the proper location of tradition, beneath the final authority of the Word, in service of the Word, accountable to the Word. Nobody gets a pass. Not Rome. Not the NAR. Not the Westminster Assembly. Not the Synod of Dort. Not the Council of Nicaea.
The Word alone is the rule. Everything else is a fallible human attempt to summarize, apply, and transmit the Word’s teaching. Valuable when faithful. Correctable when not. That is Sola Scriptura.
Tomorrow, Day 7, what the Bible says about itself.
