"Sense of community is ... a feeling that members have of belonging and being important to each other, and a shared faith that members’ needs will be met by the commitment to be together. These dynamics are incorporated in the sense of community model ... (with) four dimensions:
• Membership which creates feelings of emotional safety with a sense of belonging to, and identification with, the larger collective;
• Influence which characterizes the reciprocal relationship of the individual and the community in terms of their ability to affect change in each other;
• Fulfillment of Needs, which enables individuals to get their needs met through cooperative behavior within the community, thereby reinforcing the individuals’ appropriate community behavior; and
• Emotional Connection which is the emotional support stemming from the struggles and successes of community living.
This model accommodates 'community' conceptualized as a geographical territory (neighborhood), and as a relational network (work, political, or recreational interests)."

'Body' is metaphorical in that it refers to a group of people that are so unified as to be like a single body. Refers to solidarity, pride, devotion and honor of each member with respect to the group." http://en.wikipedia.org/wiki/Esprit_de_corps_%28disambiguation%29
