Stephen Carter argues that American politics is unimaginable without America's religious voice. Using contemporary and historical examples, from abolitionist sermons to presidential candidates' confessions, he illustrates ways in which religion and politics do and do not mesh well and ways in which spiritual perspectives might make vital contributions to our national debates. He also warns us of the importance of setting out some sensible limits, so that religious institutions do not allow themselves to be seduced by the lure of temporal power, and offers strong examples of principled and prophetic religious activism for those who choose their God before their country.
