Theologian/Philosopher Paul Tillich described religion as man's quest for the "ultimate concern."
Tillich wrote on the boundaries of the "God is Dead" movement, and he wanted to expand the definition of "religion" beyond the walls of the cathedral. He noted that many people had abandoned traditional religion, but nevertheless could be described as deeply religious because of the passion with which they pursued meaning in life.
Tillich therefore re-defined religion as "ultimate concern."
Every human being has some "ultimate" in his life. It doesn't have to be a Deity in the Biblical sense or in the sense of any knock-off of Biblical Faith, such as Islam or Mormonism.
This "ultimate concern" is the basis for our actions, including the act of legislating morality, the legislation of right and wrong for ourselves, our family, our business, and our society.
