I agree. But the problem with that approach is people are forced to recognize that doctrinal differences are sometimes differences in reasoning, understanding, presuppositions, etc., and not always one party denying Scripture itself. We (myself included) are not always charitable when it comes to differing positions. I think it is often because those differences are a rejection of our reasoning rather than Scripture and therefore personal, but we seldom admit to it.
Problem is that when we build our theology on first we our church/pastor/teacher/school states is true, and then grab those proof texts to support them!
