Is Sola Scriptura in the Bible?

No competant Lutheran, Confessional Anglican, or Reformed ever believed in solo Scriptura. Sola Scriptura, yes, with eyes and ears to patrology. No question about that. See the Helvetic Confession for amplification.

Is Sola Scriptura in the Bible?

No, and yes. The Bible does not have specific text that suggests that the Bible alone is our final authority in all matters of faith and practice. Those who delight to point this out, however, typically Roman Catholics and the eastern Orthodox, typically miss the point. First, their energies more often than not are aimed at the Anabaptist error that we call solo Scriptura. Here the person affirms that all he needs is himself and his Bible. The wisdom of the church in history, the community of believers, are all deemed irrelevant to understanding the things of God. Solo scriptura is reprehensible and ignorant and a-historical.

Sola Scriptura, like the Scriptures themselves, recognizes that God has gifted the church with teachers and pastors. It recognizes that the church has progressed and reached consensus on critical issues in and through the ancient ecumenical creeds. It affirms with vigor that we are all standing on the shoulders of giants. But it also affirms that even these giants have feet of clay. And there is where the Bible does in the end teach sola Scriptura.

Sola Scriptura is a biblical doctrine not because the Bible says so. That would be a tautology- the kind of argument we find in that collection of lies the Book of Mormon. Instead the Bible is our alone final authority because it alone is the Word of God. It has been attested, authenticated, by God Himself. Miracles serve as the divine imprimatur, the proof that this is a message of God. This is how Nicodemus reasoned when he said, "Rabbi, we know that You are a teacher come from God; for no one can do these signs that You do unless God is with him" (John 3:2). This is also how Jesus Himself reasoned when He first forgave the sins of the paralytic lowered through the roof. In response to the unspoken charge that He had blasphemed, Jesus told the man, "Arise, take up your bed, and go to your house" (Matthew 9:1-8).

I would be quite content to add as a second infallible and inerrant authority the ancient creeds of the church under the following conditions. First, those who gathered to formulate these creeds would need to have their message authenticated by miraculous works. Let them raise men from the dead. Second, we must add those creeds to our Bibles. If both sources are equally authoritative, why do we separate them? In like manner, I'd be content to add as a second infallible and inerrant authority the statements of the Pope when He speaks ex cathedra. First, however, let him raise men from the dead. Second, let us add his words, assuming he would even tell us what they were, to our canon.But wait, there's more. I want an authoritative list, in both instances of what these messages are. Ask someone Orthodox to show you exactly where you can read their infallible tradition and you will receive slippery ooze. Ask someone Roman Catholic for a list of infallible papal or consiliar statements, and you will receive the same.

Finally, there is this problem. In both instances, Rome and Orthodoxy, you run headlong into the problem of the infinite regress. That is, those who are less strident in their views on tradition, who deny that tradition carries additional content to the Scripture, instead argue that tradition gives an infallible and inerrant interpretation of Scripture. Okay. Where then can we find an infallible and inerrant interpretation of the interpretation? Assuming we could succeed there, of course, we would need an inerrant interpretation of the interpretation of the interpretation. Ad nauseum.

No, the Bible is God's Word. It is perspicuous, understandable. It says what it means and means what it says. It is attested by the miraculous power of God. And it is all these things, alone. It alone, all by itself, equips us for every good work. Flee anyone who tells you that more is required to understand, or more is required to obey.If you'd like to learn more, I'd encourage you to get and read my friend Keith Mathison's outstanding book The Shape of Sola Scriptura.
