Sola Scriptura: "The teaching that the Scriptures contain all that is necessary for salvation and proper living before God"
In the Bible:
"... from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus.
All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work." - 2 Tim 3
I recommend a book called Not By Scripture Alone: http://www.catholicintl.com/products/scripture.html It deals thoroughly with 2 Tim 3 and the other passages prots use. It simply does not mean what you want it to mean. The NBSA book has the reasons.
