"An important contribution to our understanding of the public influence of mainline Protestantism. This well-written and expansive book reveals how socially, civically, and politically active mainline Protestantism continues to be in American society, contrary to much conventional wisdom. Yet it shows the mainline influence as having a particular character, different from that of other religious traditions. Mainline Protestantism has, without justification, been understudied lately. This landmark book puts it back on the map and will generate discussion and inquiry for years to come." -Christian Smith, author of The Secular Revolution
