Is Scripture our only authority or our final authority?
Question 1032
This question gets to the heart of how we make decisions about faith and practice. When Christians disagree—and we do—what settles the matter? Is Scripture the only voice we listen to, or is it the final voice among several? The distinction matters more than you might think, and getting it wrong leads to serious problems in either direction.
Understanding the Question
When we ask whether Scripture is our “only” authority or our “final” authority, we’re really asking about the relationship between the Bible and other sources of knowledge, wisdom, and guidance. Does Scripture stand alone, rejecting all other input? Or does it stand supreme, as the ultimate judge over other legitimate but lesser authorities?
The Reformers used the phrase sola Scriptura—Scripture alone. But this has often been misunderstood. They didn’t mean Scripture is the only thing Christians should ever read or the only source of any knowledge whatsoever. They meant Scripture alone has the authority to bind the conscience in matters of faith and practice. It is the supreme and final authority, not the only source of information or wisdom.
Think of it this way: a judge in a courtroom listens to witnesses, considers evidence, and hears arguments from lawyers. But the judge has final authority to render the verdict. The witnesses aren’t ignored—their testimony matters—but the judge’s ruling is decisive. Scripture functions as that final judge over all other sources of authority in the Christian life.
Scripture as Final Authority
The Bible presents itself as the supreme authority over all human opinion, tradition, and teaching. Isaiah 8:20 declares, “To the teaching and to the testimony! If they will not speak according to this word, it is because they have no dawn.” Everything must be measured against God’s revealed Word.
Jesus repeatedly subordinated human traditions to Scripture. In Mark 7:8-9, He rebuked the Pharisees: “You leave the commandment of God and hold to the tradition of men… You have a fine way of rejecting the commandment of God in order to establish your tradition!” Human tradition, however ancient or well-intentioned, must bow to Scripture when they conflict.
Paul commended the Bereans because “they received the word with all eagerness, examining the Scriptures daily to see if these things were so” (Acts 17:11). Notice: they didn’t reject Paul’s teaching outright, but neither did they accept it uncritically. They tested apostolic teaching against Scripture. If even apostolic preaching was to be tested against the written Word, how much more should we test everything else?
In Galatians 1:8, Paul makes an astonishing statement: “But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.” Not even an apostle, not even an angel, has authority to contradict the Gospel found in Scripture. The written Word stands in judgement over every other voice.
Other Legitimate Authorities
But here’s where we need balance. Scripture acknowledges other authorities that God has established—they’re just not ultimate authorities.
God has established governing authorities. Romans 13:1 says, “Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God.” Government has real authority—but it’s delegated authority, and when it contradicts God’s Word, “we must obey God rather than men” (Acts 5:29).
God has established church leadership. Hebrews 13:17 instructs, “Obey your leaders and submit to them, for they are keeping watch over your souls.” Elders and pastors have genuine authority in the church—but that authority is exercised under Scripture, not alongside it or above it. A pastor who contradicts Scripture has exceeded his authority.
Parents have authority over children (Ephesians 6:1), employers over employees (Ephesians 6:5), and there’s wisdom to be gained from teachers, counsellors, and the accumulated insight of Christians throughout history. None of these are to be dismissed. But all of them are subordinate to Scripture.
This is why we say Scripture is our final authority rather than our only authority. We listen to many voices, but Scripture has the last word. We value tradition, but tradition doesn’t trump the text. We respect church leaders, but leaders are accountable to the Word they teach.
The Danger of “Only Authority”
Some Christians, in their zeal to honour Scripture, effectively claim it as their only authority, dismissing any role for teachers, tradition, or the wisdom of the church throughout history. This sounds pious but creates real problems.
For one thing, it’s not how Scripture describes itself. Paul appointed elders and teachers precisely because Christians need help understanding and applying God’s Word. Ephesians 4:11-12 tells us that Christ “gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry.” If Scripture alone were sufficient without any teaching ministry, why did Jesus give teachers to the church?
For another, the “only authority” approach often leads to individualism. If it’s just me and my Bible, with no accountability to the teaching of the church or the wisdom of believers throughout history, I can make Scripture say whatever I want. The history of the church is littered with people who claimed to follow “the Bible alone” while teaching obvious error. We need the corrective of the community—not to override Scripture, but to help us read it rightly.
The Reformers never taught that every individual Christian, in isolation, could correctly interpret Scripture without any help. They insisted on the perspicuity (clarity) of Scripture on essential matters, but they also valued creeds, confessions, catechisms, and the teaching ministry of the church. These didn’t compete with Scripture; they served it.
The Danger of Undermining Final Authority
The opposite error is equally dangerous. If we allow tradition, experience, reason, or church pronouncements to stand on equal footing with Scripture, we’ve effectively made Scripture subordinate to whatever authority we choose to elevate.
This is precisely what happened in medieval Catholicism, where church tradition and papal decrees were treated as equal to Scripture—and in practice, often superior to it. When Luther challenged indulgences from Scripture, he was told that church tradition authorised them. When he appealed to the Bible, he was told that only the church could authoritatively interpret the Bible. Scripture had become captive to an institution.
The same danger exists today in different forms. Some elevate experience—”I know this is true because I felt God tell me”—to equal authority with Scripture. Others elevate reason—”This can’t be what Scripture means because it doesn’t seem fair to me.” Still others elevate contemporary culture—”The Bible’s teaching on this topic is outdated and must be reinterpreted for our enlightened age.” In every case, something other than Scripture has become the functional final authority.
How This Works in Practice
So how do we hold this together? We listen to many voices but let Scripture have the final word.
When studying a passage, we might consult commentaries, read what the church fathers said, consider how this text has been understood throughout history. These are valuable voices. But if our study of Scripture itself leads to a different conclusion than what a commentator argues, Scripture wins. The commentary serves the text; it doesn’t master it.
When a church tradition has been practiced for centuries, we should be slow to dismiss it. There’s often wisdom in long-standing practice. But if that tradition contradicts the clear teaching of Scripture, we must follow Scripture. Longevity doesn’t confer authority.
When we have a strong subjective experience—a feeling of guidance, a sense that God is speaking—we don’t dismiss it, but we test it. Does it accord with Scripture? If not, the experience must yield. Feelings are real but not authoritative.
When our reason rebels against a biblical teaching, we ask whether we’ve understood the text correctly. But if we have, we submit our reason to revelation. God knows more than we do.
Conclusion
Scripture is not our only authority in the sense that we ignore everything else—that would be neither biblical nor wise. But Scripture is our final authority, the supreme court to which all other voices must answer. We value tradition, respect church leadership, benefit from teachers, and acknowledge God-given authorities in various spheres of life. But none of these are ultimate. When they conflict with Scripture, Scripture prevails. When they accord with Scripture, they serve it. This is what the Reformers meant by sola Scriptura—not a lonely Bible isolated from the community of faith, but a supreme Bible that rules over the community of faith and everything else besides.
