for whom is it?

I understand the importance of education when it comes to doing theology. Yet I still wonder for whom theology really exists, and who are its proper practitioners. Must one have a doctorate in theology before one can possess genuine theological insight? I don't think so. But at the same time, genuine theological insight implies the ability to think within the tradition one inhabits. That habit of thought is not acquired overnight. Does this habit of thought not ultimately come down to the "mind" which was in Christ according to the author of the kenotic hymn of Philippians 2?
