Organised religion requires an inflow of money to keep the system going. It has largely done this through the giving of its members who gather on Sundays or on other days of the week. When the people flow dries up so does the money flow unless it can rely on the income derived from property, investments etc.
My observation is that much church life is about gathering people (the shrinking few) and trying to get more out of them both in commitment to the organisation and in financial terms.
The key difference here for me is the difference between inward focused religious life and outwardly focused religious life. Unfortunately I think whether we have churches organised around one leader or supported by a resource minister we can be still maintaining the inward focused flow. So often the flow from the church is disillusioned hurt people like a trail of blood from a wounded dying animal rather than a flow like a river of life nourishing the world.
