I used to work with a guy who did consulting with Baptist churches on the side. He indicated that folks would drive 20 minutes before distance became a factor. So your 'community' probably includes a footprint reaching about a 20 minute drive in any direction from the church. Unless you are in a sparsely populated rural area or the heart of whitebread suburbia (if there is such a thing anymore) there's probably going to be quite a bit of diversity within that footprint. So the question then becomes whether the congregation will (and can) reach everyone in the community or whether it is going to target subsets and let others target other subsets.Do you think that a church ought to do studies of the community in which it finds itself in order to best reach it?
