Church Models

The first module presentation (Ready) for the St. Louis Association inspired a conversation regarding church models which are in place. There are certain expectations for church leadership - who is a minister? Paid staff? All participants in congregation?
Expectations/models for governing structure include ideas for a certain number of committees with a specific number of persons on each committee, with a specified number of meetings per year. Does this structure continue to serve the Body of Christ, or is it the other way around?
Do we set the annual budget and simply expect the funds to appear, or does vision/mission proceed the budget discussions?
What new models for Church might be helpful?
Please share your insights with others here.
