The faculty at Westminster Seminary California have written a book defending the Reformational doctrine of justification from its "enemies," Norman Shepherd, FV and NPP.
A fellow named Mark Garcia wrote a review of this work, and his review has elicited a response from Drs. Godfrey and Vandrunen. Here is a clarification Mr. Garcia wrote anticipating some of the challenges in the Godfrey/Vandrunen rebuttal.
Lee Irons offers some thoughtful considerations of the issues involved here. And here, Mr. Irons sheds light on the theological similarities between Norman Shepherd and N.T. Wright.
The Shepherd/FV side has now published a response to Westminster, which I intend to get as soon as possible.
