The Final Authority

Are the Five Solas in the Bible? Part 6


The Greek New Testament began being printed in 1516. The Reformation began in 1517. The Bible is the book that sparked the Reformation.

The reason that we can be sure that our being made spiritually alive, and God’s being 100% for us in Christ, is by God’s grace alone, on the basis of Christ alone, received through faith alone, all to the glory of God, is because God wrote a book. God’s word then, not a pope’s, parent’s, or popular opinion, has final authority.

The Reformers stood upon the word of God. Before his opponents, Luther cried,

Unless I am convinced by Scripture and plain reason — I do not accept the authority of the popes and councils, for they have contradicted each other — my conscience is captive to the word of God. I cannot and I will not recant anything, for to go against conscience is neither right nor safe. God help me. Amen.

As believers, we stand with the Reformers upon God’s word.

Key Texts

Galatians 1:6–9: “I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel — not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. 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. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.”

1 Corinthians 14:37–38: “If anyone thinks that he is a prophet, or spiritual, he should acknowledge that the things I am writing to you are a command of the Lord. If anyone does not recognize this, he is not recognized.”

Jude 1:3–4: “Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints. For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ.”

Series: Are the Five Solas in the Bible?

This year marks the 500th anniversary of the Protestant Reformation. The Reformers were men and women shaped by a book. They looked at the book, studied the book, memorized the book, and their (re)discoveries of essential Christian truths in the book changed the course of history.

In this lab series, we aim to look at the book with them. We will take each of the five solas and judge for ourselves whether what we believe aligns with what God has said.


Martin Luther didn’t stand alone 500 years ago. Nor does he stand alone today.

To mark the 500th anniversary of the Reformation, we invite you to join us on a 31-day journey, beginning October 1, just 5–7 minutes each day, to meet the many heroes of the Reformation.
