H. Richard Niebuhr (1894-1962): His face is as impressive as his
eloquent blast against sinful denominationalism
Denominationalism thus represents the moral failure of Christianity. And unless the ethics of brotherhood can gain the victory over this divisiveness within the body of Christ it is useless to expect it to be victorious in the world. But before the church can hope to overcome its fatal division it must learn to recognize and to acknowledge the secular character of its denominationalism.
