The thesis that I want to advance is a simple one: It is that service is rooted in religion. Service is religious in the sense that it expresses our bondedness with the universe (religare: to bind fast), and by extension with one another. Over time, service-oriented activities may become rationalized, institutionalized, and secularized. But the roots of service remain religious.
