There seems to be a very large group of people for whom faith is a real and central part of their lives, but for whom the institutional church is a spirituality-killer - and for whom Greenbelt is their 'church'.
Thought one: you can't be a Christian on your own.
Thought two: you don't need an insitution to be a Christian.
Thought three: how long before Greenbelt itself becomes an institution that 'believers' need to break away from in order to be authentic to themselves.
There is more here to be discerned...
