I can't know your heart, but you really should think about what we mean when we say Sola Scriptura. The belief is often misstated for the purpose of ridicule. The best example of it is the Bereans and the high esteem they were held in because they adherred to it.
This is yet another in an unending progression of threads about Catholicism that is hijacked by Protestants who want to ridicule Catholics saying two thousand years of Catholic teaching is wrong.
And yet I am unfamiliar with any Protestant threads being hijacked by Catholics ridiculing Protestantism's Sixteenth Century theological inventions.
If any of us were to go onto a Jewish thread and tell the Jews that they were damned for not accepting Christ, we would be banned from Free Republic. So, forgive me if I am simply uninterested in "thinking about what Protestants" mean when they talk about theories that the Catholic Church holds to be heretical.
The Bereans only had the Old Testament available to them as Scripture.`
