I just tripped over some Reinhold Neibuhr recently- a "neo-orthodox" or "Christian realist" theologian, his is a complicated story. He was a liberal protestant during the Progressive era, then became an isolationist after WWI. Then he did this "Christian realist" thing because communism had failed and the nazis were evil, so a "realistic Christian" had only the choice of the lesser of evils. His pessimism was an influence on John Dos Passos, mark 2, and James Gould Cozzens, expounding on maturity as the ability to live in an imperfect, ironic world...but it can be read as an apology for apathy, too. Is my source on the mark, Julie?
