Don Garlington is asking, "What's it all about" when a group of people articulate similar views on 1) the relationship between faith to obedience (Rom. 1:5) and 2) the necessity of works during the final judgment (Rom. 2:13) but some get attacked because of these views but others don't.
"I ask again, What's it all about? If the likes of Bucer, Schreiner, Candeay, Seifrid, Dunn, Wright, Bird, Mounce, Shepherd, and others of us, are in essential accord as to Rom 1:5; 2:13 (and other texts), then why does there continue to be internecine warfare among believers of the same stripe? Or, more pointedly, why is there a persistent double standard imposed on those who are more alike than different?"
Through my reading of things on Paul and justification,I have asked the same question. But it appears to me that the major reason why some people get attacked and other don't is because one group affirms the Westminster Confession view of Christ's imputation with it's underlying notion of the "covenant of works" (Scheriner, Seifrid, and Bird), while others don't (Wright, Garlington and Shepherd) 
 I am not sure about Candeay's, Bucer's, Mounce's, or Dunn's views on imputation.
