When I read this post, initially, I thought four things.
1. I am glad to see a zeal for the Word of God.
2. I am sad to see that they this type of belief seems to reject wisdom of Godly people throughout the ages.
3. Isn't this type of group denominating?
4. I think this is rather presumptious to assume that others are not trying to derive what they believe from the Bible.
To me, rejecting the wisdom of other Godly men and women throughout the ages is foolish. I am not saying we should agree with old saints, but they sometimes have insights and wisdom into the things of God and the Bible that we need and can benefit. Often, relying upon myself I may not have the wisdom of others and understanding their viewpoint can help keep me from error. Even this week, I was reading a treatise from a much wiser man and saw the error of my previous theology in a certain area. Left to myself, I may never have fully realized my error. Yet, God gave us a long history of people to challenge our beliefs.
Yes, I think my beliefs are Biblical. Yet, I also rely upon wisdom from great men of the past to challenge me, encourage me, and to help me weight their arguments against scripture. I am much better for having done so.
Ultimately, a belief that says "Just me and my Bible" will end in error. Rather, I believe in Sola Scriptura. Rather, I believe in preaching and I believe great men have insight in areas where I am weak. I need the greats of the past to help me dig deep in areas where I am shallow.
