The idea of coomunity in the bible is to encourage and support each other. As the show has progressed, the community has gotten more complex, and the original survivor group has encountered other communities.

A healthy community will choose strong leaders, adopt a moral code and plan for the future. The group led by sheriff Rick Grimes has done these things. They've had their ups and downs, but they realized the importance of community early on.

Yet the point, as we soon learn, is not community alone but how community is cultivated and maintained.
