One of the distinctive Protestant principles is expressed in the slogan sola scriptura, which is Latin for “by Scripture only.” The idea is that every teaching on faith or morals must be directly or indirectly based on the Scriptures.
That leads to the common question, “Where’s that in the Bible?”
It’s an important question. In fact, it’s a question that needs to be asked about the doctrine of sola scriptura itself. Because if every teaching on faith or morals has to be based on the Bible thensola scriptura must be based on the Bible.
If it’s not, then it is a self-refuting claim and is false.
So what passages do Protestant Christians appeal to in support of sola scriptura?
