That’s a bad idea, since the bible cannot speak for itself. That is the main reason there are so many conflicting “bible-only” churches. For example, we Catholics (and Orthodox) think that John 6 clearly speaks for itself, but most of the Protestant world doesn’t see it.
Conflicting opinions abound all over. In those who claim adherence to scripture and tradition, disagreements occur. Disagreements that speak to the fundamental truth of their claims. Do not the Orthodox and Catholic disagree over the Pope?
The key issues that seperate Christians from those who preach a false gospel is their unwillingness to let the Bible be the final guide. They are either Bible correctors, “Greeking” their Bible to promote their preconceived notions, or they lack proper dispensational understanding. They have to rationalize James and Paul and fail to see the audience, one of the keys to rightly dividing the word of truth, for whom the letter was written.
I’m still not clear on your position. In the normative (usual) case, is obedience necessary for salvation or not?
