"Just as Martin Luther King Jr. learned much from Reinhold Niebuhr, Niebuhr could have deepened his understanding of the cross by being a student of King and the black freedom movement he led. King could have opened Niebuhr's eyes to see the lynching tree as Jesus' cross in America. White theologians do not normally turn to the black experience to learn about theology. But if the lynching tree is America's cross and if the cross is the heart of the Christian gospel, perhaps Martin Luther King Jr., who endeavored to "take up his cross, and follow [Jesus]" (Mark 8:34) as did no other theologian in American history, has something to teach America about Jesus' cross."
