The phrase sola scriptura is from the Latin: sola having the idea of “alone” “ground,” “base,” and the word scripturameaning “writings”—referring to the Scriptures. Sola scriptura means that Scripture alone is authoritative for the faith and practice of the Christian. The Bible is complete, authoritative, and true.
“All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness” 2 Timothy 3:16
Sola scriptura was the rallying cry of the Protestant Reformation. For centuries the Roman Catholic Church had made its traditions superior in authority to the Bible. This resulted in many practices that were in fact contradictory to the Bible. Some examples are prayer to saints and/or Mary, the immaculate conception, transubstantiation, infant baptism, indulgences, and papal authority. Martin Luther, the founder of the Lutheran Church and father of the Protestant Reformation, was publicly rebuking the Catholic Church for its unbiblical teachings. The Catholic Church threatened Martin Luther with excommunication (and death) if he did not recant. Martin Luther’s reply was..
“Unless therefore I am convinced by the testimony of Scripture, or by the clearest reasoning, unless I am persuaded by means of the passages I have quoted, and unless they thus render my conscience bound by the Word of God, I cannot and will not retract, for it is unsafe for a Christian to speak against his conscience. Here I stand, I can do no other; may God help me! Amen!”
The primary Catholic argument against sola scriptura is that the Bible does not explicitly teach sola scriptura. Catholics argue that the Bible nowhere states that it is the only authoritative guide for faith and practice. However, this is only true in the shallowest sense. The principle is strongly indicated by verses such as Acts 17:11, which commends the Bereans for testing doctrine—taught by an apostle, no less—to the written Word. Sola scriptura is all-but-explicitly indicated in 1 Corinthians 4:6, where Paul warns not to “go beyond what is written.” Jesus Himself criticized those who allowed traditions to override the explicit commands of God in Mark 7.
“He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctrines the commandments of men. For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.” Mark 7:6–9
Whether sola scriptura is overtly mentioned in the Bible or not, Catholicism fails to recognize a crucially important issue. The Bible declares itself to be God-breathed, inerrant, and authoritative. We know that God does not change His mind or contradict Himself. So, while the Bible itself may not explicitly argue for sola scriptura, it most definitely does not allow for traditions that contradict its message. Sola scriptura is not as much of an argument against tradition as it is an argument against unbiblical, extra-biblical and/or anti-biblical doctrines. The only way to know for sure what God expects of us is to stay true to what we know He has revealed—the “Holy” meaning set apart, “Bible” meaning Book. We know, beyond the shadow of any doubt, that Scripture is true, authoritative, and reliable. The same cannot be said of tradition.
The Word of God is the only authority for the Christian faith. Traditions are valid only when they are based on Scripture and are in full agreement with Scripture. Traditions that contradict the Bible are not of God and are not a valid aspect of the Christian faith. Sola scriptura is the only way to avoid subjectivity and keep personal opinion from taking priority over the teachings of the Bible. The essence of sola scriptura is basing your spiritual life on the Bible alone and rejecting any tradition or teaching that is not in full agreement with the Bible.
“Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.” 2 Timothy 2:15
Sola scriptura does not nullify the concept of church traditions. Rather, sola scriptura gives a solid foundation on which to base church traditions. There are many practices, in both Catholic and Protestant churches, that are the result of traditions, not the explicit teaching of Scripture. It is good, and even necessary, for the church to have traditions. Traditions play an important role in clarifying and organizing Christian practice. At the same time, in order for these traditions to be valid, they must not be in disagreement with God’s Word. They must be based on the solid foundation of the teaching of Scripture. The problem with the Roman Catholic Church, and many other churches, is that they base traditions on traditions which are based on traditions which are based on traditions, often with the initial tradition not being in full harmony with the Scriptures. That is why Christians must always go back to sola scriptura, the authoritative Word of God, as the only solid basis for faith and practice.
As a practical matter, a frequent objection to the concept of sola scriptura is the fact that the canon of the Bible was not officially agreed upon for at least 250 years after the church was founded. Further, the Scriptures were not available to the masses for over 1500 years after the church was founded. How, then, were early Christians to use sola scriptura, when they did not even have the full Scriptures? And how were Christians who lived before the invention of the printing press supposed to base their faith and practice on Scripture alone if there was no way for them to have a complete copy of the Scriptures? This issue is further compounded by the very high rates of illiteracy throughout history. How does the concept of sola scriptura handle these issues?
The problem with this argument is that it essentially says that Scripture’s authority is based on its availability. This is not the case. Scripture’s authority is universal; because it is God’s Word, it is His authority. The fact that Scripture was not readily available, or that people could not read it, does not change the fact that Scripture is God’s Word. Further, rather than this being an argument against sola scriptura, it is actually an argument for what the church should have done, instead of what it did. The early church should have made producing copies of the Scriptures a high priority. While it was unrealistic for every Christian to possess a complete copy of the Bible, it was possible that every church could have some, most, or all of the Scriptures available to it. Early church leaders should have made studying the Scriptures their highest priority so they could accurately teach it. Even if the Scriptures could not be made available to the masses, at least church leaders could be well-trained in the Word of God. Instead of building traditions upon traditions and passing them on from generation to generation, the church should have copied the Scriptures and taught the Scriptures.
“Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine.” 2 Timothy 4:2
Again, traditions are not the problem. Unbiblical traditions are the problem. The availability of the Scriptures throughout the centuries is not the determining factor. The Scriptures themselves are the determining factor. We now have the Scriptures readily available to us. Through the careful study of God’s Word, it is clear that many church traditions which have developed over the centuries are in fact contradictory to the Word of God. This is where sola scriptura applies. Traditions that are based on, and in agreement with, God’s Word can be maintained. Traditions that are not based on, and/or disagree with, God’s Word must be rejected. Sola scriptura points us back to what God has revealed to us in His Word. Sola scriptura ultimately points us back to God who always speaks the truth, never contradicts Himself, and always proves Himself to be dependable.
