This provocative study argues that the 'believers' church' should draw on Catholic, Reformed, and Lutheran thought to find a solid basis for Christian political action. The book believes that a 'believers' church' ethic has points of continuity with the quest for social justice in the larger society. Rather than separating discipleship from political life or uncritically baptizing political projects, the believers' church may appeal to natural law as a basis for cooperation with others toward the end of a more just society. The volume draws upon various historical theologians and a variety of contemporary figures to affirm a God-given moral capacity in humans that makes a tolerably just political order possible.
