It is not something which pervades our life. Nor is it something we learn much about in life. We learn about being consumers - about exchanging fees for services and goods. This is the backbone of society today, and sociologists from the 19th century on have been talking about how this economic model of consumerism has dismantled community. It's quite a short list, but on that list is the Church.
Interdependence is a value of our congregation.
We want people to know they can rely on their church in their need. We want people to know we all have a part in contributing to meet the needs of those around us when they arise. Reciprocity is about giving and receiving. One of my classic lines about church membership is that we are all called to receive from the congregation so as to meet our needs, and we are also called to contribute to the congregation from our strengths. In an engine you have several pistons.
