The Barack Obama and Donald Trump administrations have scumbled long-standing visions of America's role in the world. During times past, the then-regnant “mainline” Protestantism might have addressed matters, but its intellectual impact has eroded. Are any resources from this or other segments of American religion equipped to provide moral guidance on foreign policy for such a confusing time?

 That’s a big fat story theme, which brings us to the current boomlet to reclaim the “Christian realism” of theologian Reinhold Niebuhr (1892-1971). Niebuhr was deemed the nation’s “greatest living political philosopher” by his ally Hans Morgenthau, a noted foreign policy analyst. In more recent times, Niebuhr has been lauded by former Democratic Presidents Obama and Jimmy Carter.

Yet, surprisingly for a theological liberal and longtime Socialist, Niebuhr also has moderate and conservative disciples. Jack Jenkins proposed in a May 18 ThinkProgress piece that President Trump’s “greatest ‘conservative’ opponent may turn out to be” Niebuhr. Others utter hosannas in a Niebuhr documentary premiered in January at New York’s Union Theological Seminary, where he taught for 32 years.   

Another fan, of all people, is the hyper-newsworthy James Comey, late of the FBI, who mentioned this to New York Magazine years ago. In March, Ashley Feinberg of gizmodo.com even unmasked Comey as a Twitter user under Niebuhr’s name. The Comey angle is fleshed out in “The F.B.I. and Religion,” co-edited by Sylvester A. Johnson and Steven Weitzman (University of California Press) and in a May 19 Weitzman article for Christianity Today.

Comey’s 1982 senior thesis at William and Mary compared the Reverend Niebuhr’s political theology favorably over against that of the Reverend Jerry Falwell, founder of the conservative Moral Majority. Both men cited Scripture and advocated Christian political involvement, Comey observed, but Niebuhr always recognized the ambiguities and shunned “America-first” fulminations.
