To me, it seems that a Christians’ denominational choice, is relative to what and how they believe in the bible.
You are painting in fairly broad strokes, but in some respects this may be true. Imagine, however, there are folks that think the Bible is simply a means of "encountering" God. They don't think that the information recorded in the Bible needs to be true, or even believable. They see it as just a springboard of thoughts by men about God. The folks from the Reformation would call this an error. How does it strike you?
