Love
Reinhold Niebuhr regarded love as the law of human nature. He interpreted that love as agape, identified it with God’s love, and claimed that Jesus revealed it as universal, self-transcending, forgiving, non-resistant, and sacrificial. According to Niebuhr such love produces harmony yet humans inevitably succumb to something less. This inveterate shortcoming grounded Niebuhr’s Christian Realism and concentrated his social ethics on justice, which he related to love dialectically. It also shaped Niebuhr’s exposition of the Christian Gospel as primarily disclosure of God’s forgiveness, which enables human beings to love self-transcendently and thus fulfil their nature by freeing them from their failure to do so. Niebuhr’s account of love stimulated widespread interest in the topic and extensive criticism of his proposals. Nonetheless, Niebuhr argued that the paradoxical relationship of sacrificial and mutual love in history validated that account and the social ethics and soteriology he connected to it.
