In 45 years of Christian school, camp, VBS, Bible Study, college and church attendance, I’d never heard the words Sola Scriptura until I read Patrick Madrid’s Surprised by Truth (a wonderful book instrumental in my conversion, but completely wrong as far as what Protestants believe) and later came to Catholic Answers forums where people seem to be obsessed by it.
As far as I have ever heard, known or been taught, what Catholics and Patrick Madrid call “Sola Scriptura” is not at all what any Protestant I have ever known believes. There may be some wacky fringe groups - I’m not at all familiar with what denominations like Westboro Baptist Church, for example, believe - but your typical mainstream evangelical denominations don’t believe what Catholics call Sola Scriptura.
For Protestants, it means that the Bible is infallible. It doesn’t mean that no other authority exists or no tradition exists. It just means that those authorities, knowledge or tradition are subordinate to scripture. Reason, tradition, church authority, the Holy Spirit, etc are all valid as long as they don’t contradict scripture. Scripture is infallible, but human beings are not, church leaders are not, our ability to reason or understand is not, therefore, we must ensure that the fallible is subordinate to the infallible.
Catholics seem to think it means that scripture is the only thing available or believed, and that it contains all knowledge. I believe that is a perversion of the Protestant belief so you can’t argue your version of Sola Scriptura with a Protestant or use Bible verses to show that your version isn’t true. Protestants already don’t think your version is true and they won’t be using any verses of the Bible to back it up. They won’t have any idea what you are talking about.
