Lecture 2: Sola Scriptura: Is Scripture All We Need?

The lecture, section by section

1. Protestant, Catholic, evangelical: getting the names right

   Before the arguments, the teachers contest the labels. The Reformation was fought over two things, sola scriptura and justification by faith alone, but the name Protestant no longer fits, since no one today is protesting the sixteenth-century establishment. The teachers refuse to concede the word Catholic to Rome: catholic means universal, and evangelicals claim to be the ones who carried on the universal faith held from the church’s beginning. Better names are Catholic first, reformer second; the church headquartered in Rome is best called the Roman church. The goal is not point-scoring but unity: believers across the traditions share far more than divides them, and the course wants to celebrate the commonality while being honest about the differences.

2. The question and the five views, reviewed

   The question of the night: is Scripture all that we need? Is it merely at the front of the stage of truth, or the only thing on the stage? The five views return in summary: sola ecclesia, the dual-source view, where the church’s magisterium interprets Scripture and defines the canon; prima scriptura, where Scripture takes priority over a second source; the regula fidei view, where tradition simply is Scripture in summary, the church’s orthodoxy; sola scriptura, where Scripture is the final and only infallible authority; and solo scriptura, where Scripture is the only authority of any kind. The difference between the last two carries the whole session.

3. The case for the dual source: unwritten things and spoken traditions

   The teachers argue the other side first, and at strength. Argument one: John 21:25 says the world itself could not contain the books if everything Jesus did were written, and tradition, not writing, was the ordinary way information moved in the ancient world; a print-age mindset forgets how much was carried by trained memory. Argument two: the New Testament writers themselves speak of tradition. Paul tells the Thessalonians to stand firm and hold to the traditions taught by word of mouth or by letter, two channels side by side; he praises the Corinthians for maintaining the traditions as he passed them on; and Jude urges believers to contend for the faith once for all entrusted to the saints, an entrusting, not a writing.

4. The case for the dual source: Polycarp’s question

   Argument three is apostolic succession, and the teachers make the class feel it. Who knows more about Christ, you or John, who walked with him three years? John discipled Polycarp, bishop of Smyrna, the church addressed in Revelation, one generation from Christ, a native speaker of the common Greek of the New Testament, martyred after decades of faithful service when the wind blew out the first fire set to burn him. Polycarp discipled Irenaeus, bishop in Lyons. Who knows more, Irenaeus or us? We assume our generation finally put it together, yet a commentary written closer to the sources may know things ours cannot. Add the texts where Christ hands authority: whatever you bind on earth will have been bound in heaven; Matthew 16, where Peter confesses and receives the keys of the kingdom; and Acts 1, where Judas’s office is filled, a precedent, on this reading, for succession. Discipleship itself, twelve men sent to make disciples who make disciples, seems to point the same way when seen through first-century eyes.

5. The case for the dual source: canon and unity

   Argument four is the most troubling for Protestants: without an infallible declaration of the church, how do you know which books belong in the canon? Scripture has no inspired table of contents, so the critic says the Protestant holds a fallible canon of infallible books, and what good is that? Some even take a halfway position, dual source only until the canon was established. Argument five is unity: without an infallible authority, who decides between Athanasius and Arius when both hold the same Scriptures? Christ prayed in John 17 that his people would be completely one so the world would know the Father sent him, and, the argument runs, sola scriptura has produced not oneness but the famous thirty-three thousand denominations. The teachers pause here: these are not foolish arguments, and until you can state them as their holders do, you have not earned the right to answer them. Protestants live half of this already, yielding to pastors, confessions, and favorite authors as a functional magisterium.

6. How the papacy actually grew

   Before the responses, a history. No villain set out to seize power. A church holding one apostolic letter, with the apostles dead and no bound canon, naturally leaned on those the apostles had discipled, and a magisterium to manage the church made a kind of sense. The corruption came later: church and state fused when Christianity became the religion of the empire, infant baptism doubled as a tax registry, wealth and papal armies followed, and by the twelfth and thirteenth centuries popes were canceling one another’s bulls, which forced the question no one had asked before: can a pope err? The claim that he cannot, speaking alone ex cathedra through the extraordinary magisterium, was not declared dogma until 1870. The element of infallibility, the teachers argue, is what turned oversight into a problem no one could any longer appeal past.

7. Answering the unwritten things

   Now the responses. It is self-evident the Bible did not record everything Jesus said or did; John says so himself, and states his purpose: what he recorded was written so that readers might believe and have life in his name. Nothing in the text sends readers hunting for an unwritten infallible tradition; finding one there is reading in what is not present. The teachers quote John MacArthur’s point that sola scriptura does not claim everything Jesus or the apostles ever taught is preserved in Scripture, only that everything necessary, everything binding on the conscience, is. And when the dual-source advocate replies that he does not need Scripture to teach his view because tradition teaches it, the argument has become circular: tradition is infallible because tradition says so. That is question-begging, and if God truly required submission to a second infallible deposit, one explicit verse anywhere would have settled it. There is none.

8. Answering tradition and succession

   The traditions Paul commends are the gospel message itself, the summary later called the regula fidei, now contained in the New Testament, not a separate ever-growing deposit; and no one has ever explained the mechanics of how a body of teaching too large for the world’s books passes intact from bishop to bishop. On succession: Protestants also believe in apostolic succession, rightly defined, the carrying on of the apostles’ teaching, which continues today through their writings, not through an unbroken lineage of office. The authority texts concern the apostles themselves; Acts 1 fulfilled prophecy about Judas’s office and set no pattern, or else popes should be chosen by drawing lots; and nowhere in Acts or the epistles does an apostle pass on infallible authority, not once. History answers the unity claim too: the papacy was to be the great uniter, yet the Great Schism of 1054 split East from West over Roman claims, and the Reformation followed. The pope, the teachers suggest, has been the great divider, and Protestants are not the newcomers: we identify with the early church and the medieval church, see the corruption, and call ourselves reformers of the one church, not founders of a new one.

9. Answering the canon and the fear of fallibility

   On the canon, the Protestant does not seek a declaration producing absolute certainty but a recognition producing moral certainty. Yes, the collection is fallible while the books are infallible, but nearly every responsible decision in life rests on fallible evidence: no one has infallible knowledge that the sun will rise tomorrow, and no one is foolish to plan on it. The evidence for the canon compels the same confidence, as the canon sessions will show. And the dual-source position enjoys no escape from fallibility: there is no infallible list of which papal statements are infallible, so the Catholic holds a fallible canon of infallible ex cathedra statements about an infallible text, while the Protestant holds a fallible opinion about an infallible text. Both start with fallibility; sola scriptura, as the teachers put it, simply takes out the middleman.

10. Answering the unity argument

    The unity Christ prayed for was not creedal or organizational unity but ontological unity: at Pentecost the Spirit baptized all believers into one body, so the church already is one at the level of its being, as children who fight remain one family. Rome does not possess creedal unity anyway, and from the outside looking in, the Roman church appears as one choice among the thousands, not as the fulfillment of John 17. None of this excuses Protestant disunity, which believers should labor to overcome, and the teachers commend the word evangelical as a transdenominational bond. Then a deeper word: God allows tension and disagreement in the church so that his people will struggle toward deeper understanding, and truth fought for is owned as truth merely handed down never is. A magisterium that settled everything would leave a passive people with a shallow faith.

11. The positive case: sufficiency in Scripture’s own words

    The case for sola scriptura begins with 2 Timothy 3: the sacred writings are able to make wise for salvation, and all Scripture is God-breathed, theopneustos, and profitable, so that the man of God may be equipped for every good work, not some of the works, every good work. Since Roman theology folds sanctification into salvation, even its own reading yields Scripture sufficient to carry a believer to the end. Psalm 119, the longest chapter in the Bible, celebrates the word of God in verse after verse under many synonyms; nothing remotely like it exists for tradition, and tradition is never once called God-breathed. In Acts 17 the Bereans, ordinary people, are commended for examining the Scriptures daily to test even an apostle’s preaching, and the epistles are addressed to the believers of the churches, not to a magisterium: if only an infallible teaching office could interpret, the letters would have been written to it. The commands not to add to or take from God’s words, echoed with plagues attached at the close of Revelation, presuppose a fixed written standard; an unwritten tradition can never be tested against them.

12. Infallibility is prophecy, and the fathers agree

    Anyone claiming to speak infallibly is claiming to speak for God, and that, whatever it is called, is prophecy; the claimant stands where prophets and apostles stood and must show what they showed, the signs of a true apostle wrought in signs, wonders, and mighty deeds. The early fathers, read on their own terms, held an unarticulated sola scriptura: Irenaeus says the plan of salvation was handed down to us in the Scriptures, to be the ground and pillar of the faith; Clement of Alexandria will not desist until the demonstration comes from the Scriptures; Gregory of Nyssa says let the inspired Scriptures be our umpire; Athanasius calls the holy and inspired Scriptures fully sufficient for the proclamation of the truth; Basil is not content that something is the tradition of the fathers unless the fathers followed the meaning of Scripture. The historical arc: the regula fidei view first, then prima scriptura, then the dual source, then sola scriptura recovered at the Reformation, and today, most commonly among Protestants, solo scriptura, which the teachers name as a wrong turn.

13. What sola scriptura does not mean, and why it is worth the danger

    Sola scriptura does not mean there are no other authorities in the Christian life, nor that each Christian is an autonomous interpreter, nor that tradition is without value, nor that there is no institutional authority to submit to: Hebrews commands believers to obey their leaders, who keep watch over souls. Everything remains on the stage of truth; Scripture stands at the front, alone infallible. Is the doctrine dangerous? Yes, the teachers answer plainly: it opens the door to division and misuse. Is it worth it? It has to be, because Scripture is the norm of norms which is not normed, the authority over which nothing else has authority.

1. The teachers made the class argue the dual-source view at full strength before answering it. Which of its five arguments pressed you hardest, and could you state it so fairly that a Catholic friend would say you had represented them perfectly?

2. The lecture observes that many Protestants live with a functional magisterium, yielding to a favorite author, confession, or teacher as if infallible. Who sits in that seat for you, and what would testing them like a Berean look like?

3. The teachers admit sola scriptura is dangerous because it opens the door to division, and hold it anyway. How do you weigh a true doctrine that carries real costs, and what keeps liberty from becoming license in your own reading of Scripture?
