Oh; but it DOES!
2 Peter 1:3
His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness.
This, too, does not say "Sola Scriptura."
It doesn't say anything about "sola" ^OR^ "Scriptura."
By "everything" He has "given" us, it logically must include the authority of the Church, and Sacred Tradition, since Scripture itself came to us via the authority of the Church, and Sacred Tradition.
Or do you think it fell down from Heaven leather-bound, in Gothic lettering and gold leaf, round about 1517 or so?
