It could be said that the whole world is a community, which is true at a spiritual level.
By being part of a community, there are conditions of coherent belonging and impeccability which should be followed. Or, at least a serious personal aim in that direction.
You have a responsibility to your personal Spirit/Soul to have a sacred relationship, or at least the growing of this relationship, with your everyday environment.
Most importantly, there should be an understanding between the participants of a community, trust founded upon time spent together, and the shared effort of being one with the Creator, as much as possible.
