A Peculiar People: The Church as Culture in a Post-Christian Society (1996) is a book by Rodney Clapp discussing the Christian church's witness in contemporary culture.

Clapp argues against a church that has been co-opted by the larger culture.

A contingent aspect of this that Clapp argues for is the notion that the church needs to shift its understand of itself from a collection of individuals each with their own understanding, ideas, and values.

Clapp argues that the church should be transformative in the world via living as an alternative culture rather than through political means.

In essence his position is that by living a unique form of life in the world the church can bear witness to another way, and in bearing witness it can bring positive change to the larger culture.
