Wind in our sails vs. program at our bookstore

A few years ago I was assigned a paper on who runs the church.  It was designed to get us to wrestle with church polity and I think that it is an important question.  However, I always had some uneasiness with it.  At the time I couldn't quite explain it, just that I didn't like the question.  I didn't like the question so much that I didn't write the paper and therefore didn't pass the class....twice.  I never gave up wrestling with the ideas however.  I am taking a class this semester on ecclesiology...the study of the church.  Fascinating class for a variety of reasons.  Last class period we circled around to the topic of church polity.  We were laying the ground work of the Holy Spirit's role in the church.  We glanced at the book of Acts and the picture that Luke paints of the Holy Spirit in his writing.  We agreed that the picture we get from Acts is that the Holy Spirit is like wind to the sails, leading and pushing and directing us as the people of God.  That is a pretty analogy, but practically what does that look like.  The answers to that question we didn't agree on.

Tonight my friend and I were discussing large churches vs. small churches (completely ambiguous I know).  At one point in the discussion he said something to the effect of mega churches leading the way, and I had to stop him.  I had to ask the question have mega churches led the way in how we as a culture "do" church as opposed to the Holy Spirit leading churches.  I guess the answer to that question depends on how you answer how the Holy Spirit leads churches.  However, I still think that it is worth thinking about.
