No, it must by definition be "correct." Scripture can not be the final authority if it makes no such claim.
I don't really want to jump into the discussion you two have going on, but, I want to clarify for those of us who may be spectators. The Catholic Church does not place its Tradition above Scripture - no teaching of the Church can be in contradiction with Scripture. Further, we agree that the Word of God is the final authority - the difference is we consider both His written Word (Scripture) and His oral Word (Tradition) to be two sides of the same coin of His Word.
I don't doubt that either of you knew this, but, from the perspective of someone who wasn't in the discussion, I wanted to clarify that point, so that others might not get the wrong impression. Okay, out of your corners...fight! ;-)
I think the real confusion here is that the author of the article that started this thread began from assumptions that favored tradition over scripture. Endlessly going through many Protestant denominational differences with an eye to one being exclusively true in all its practices. From the Baptist, Presbyterian, Methodist, Calvary, and non-denominational churches that I have attended, and been members of, none claim exclusivity similar to what the author searches for. It's like being presented with a color spectrum and searching for the exclusively true aqua-marine.
