Reinhold Niebuhr's brother, H. Richard, argued for faithfulness to the example of Jesus's nonviolence, while Reinhold believed this was naive and unrealistic in an imperfect world. H. Richard was the purist to the Christian faith, believing that following the Golden Rule, no matter the consequences, is what Jesus and God called us to do -- the success of the mission being in God's hands rather than our own. Reinhold, however, looked at the more practical side of things, substituting his or the world's idea of what was possible and changing his ethics accordingly. H. Richard thus trusted more in the providential moral arc of history as M.L. King, Jr. , would call it rather than a realist's version of what humans believe is attainable given their corrupt nature. In essence, H. Richard focused on the power of God's grace to transform our spirits and the world for the better, while Reinhold accepted a more cynical view of our ability to be radically changed as a specie.
