I think you just made my point for reason #11 as you had to make your own interpretation to that meaning Sola Scriptura- it did not say that the scriptures and the scriptures alone are the final authority, you interpenetrated it that way. As we know through history, through the hundreds of denominations and translations, abuses and mistakes, that “Sola Scriptura” without guidance of tradition or the Holy Spirit is prone to be abused. It is the root of the phrase ‘you can prove anything with the Bible’.
Well, let's look what "Tradition" can do.
In the Catholic Church, it means Mary is your Salvation:
UBI PRIMAM 1849 Pope Pius IX: "For, God has committed to Mary the treasury of all good things, in order that everyone may know that through her are obtained every hope, every grace, and all salvation."
Note: By Tradition, Pope Pius IX made Mary ALL your Salvation, ALL your Hope and ALL your Grace - Not the Lord Jesus Christ. This is what happens when Sola Scriptura is not applied. Tradtion overwrites Scripture.
