The Presbyterian Church Struggle: Reflections on the Relevance of the Barmen Declaration by James R. Edwards, Ph. D.  PCUSA pastor and Chairman of the Religion and Philosophy Department at Jamestown College, Jamestown, ND. Edwards examines Confessionalism versus Accommodation to Culture by looking at the struggle of the German Confessing Church that was given expression in the Barmen Declaration.  "The struggle was perceived and articulated by the Synod of Barmen in terms of confessionalism versus accommodation to culture.  Specifically that meant a conflict between two understandings and models of Christianity.  The one, represented by the 'German Christians,' advocated a 'positive Christianity' that sought to integrate the gospel as far as possible with the prevailing ideology ushered in by Hitler and National Socialism. ...The other understanding of Christianity was expressed by the 'Confessing Church,' which at Barmen and subsequent synods raised a voice of protest against reformulating Christianity according to Germanic and especially Nazi archetypes."
