Sola Scriptura: The Heart of the Reformation (and the True Christian Faith)

"Within a year of posting his Ninety-Five Theses, Martin Luther was summoned to appear before Cardinal Cajetan to be examined for his accusations against the Roman Catholic Church’s theology and practice. When the Cardinal pressed him on the issue of the church’s authority, Luther responded, “The truth of Scripture comes first. After that is accepted one may determine whether the words of men can be accepted as true.”[i] Now, Luther was not discrediting the words of men completely, rather, he was claiming that, far and above anything or anyone else, Holy Scripture was first and foremost. This led to the development of Sola Scriptura—“Scripture alone.” But in order to examine this principle within the context of the Reformation, we first need to explore the doctrine of Scripture itself. For the rest of this article, we will examine four foundational claims regarding the Word of God: its inspiration, inerrancy, authority, and sufficiency.

The Issue of Inspiration- The most dynamic and explicit passage in all of Scripture about the nature of the Bible’s own divine inspiration comes in 2 Timothy 3:16-17. The Apostle Paul writes:  “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.”

In the Greek, the word theopneustos is used to describe how Scripture came to be; it was literally “God-breathed”. It was as if the Lord took a deep breath in, and then exhaled Holy Scripture. Further, the means by which God brought Scripture about was through the pens of human writers—“men [who] spoke from God as they were carried along by the Holy Spirit” (2 Peter 1:21). Both the Roman Catholic Church and the Protestant Reformers did not disagree about divine inspiration. What was and is still contested, however, is the content of the revelation.

Paul’s use of the word “all” in 2 Timothy 3:16 leads us to examine: What books of the Bible are contained in the “all” of Scripture? This is the question of the canon. The word “canon” comes from the Greek word kanōn, meaning “measuring rod”, which came to be used in speaking of a “rule” or “standard”. And in the most general sense, the canon is “the authoritative books that God gave his corporate church.”[ii] Historically, the accepted canon consists of 66 books—39 Old Testament books (Genesis to Malachi) and 27 New Testament books (Matthew to Revelation).

During the Reformation, the Roman Catholic Church asserted that there were additional books inspired by God, which belonged in the canon. What came to be known as the Apocrypha consisted of the books of Tobit, Judith, the Additions to Esther, the Additions to Daniel, the Wisdom of Solomon, Ecclesiasticus (also called Sirach), Baruch (Hebrew for Blessed), the Letter of Jeremiah, and 1st and 2nd Maccabees. In response to the Reformers’ claims that many of the Catholic Church’s practices were unbiblical, the Council of Trent (1545-1563) canonized the Apocrypha, thus deeming it to be the inspired and authoritative Word of God. But after 1,500 years of being absent from the canon, did the Apocrypha suddenly deserve to be included? Certainly not.
