Abuse of power come as no surprise

The Jenny Holzer truism should be no more applicable than in Christian communities. When you share everything and make sacrifices for a communal ideal - one that is administered by a few, its bound to happen, and I'm sure the best way of approaching setting a community up is to make the guidelines up with the assumption that it is going to happen in some form.

Having seen what happened with NOS I know how spiritually and financially devastating it can be for the individuals involved.

The question I ask myself then is, How could you build a community without power being an issue? If you are not close enough to get hurt if things go wrong, then are you not close enough to feel the benefit of community? What guidelines would you put in place to make the abuse of power more difficult?
