The February issue of the Orthodox Presbyterian Church's official publication, New Horizons, has a series of articles on the Federal Vision Controversy.  This issue is in fulfillment of the recommendations approved by the 2006 OPC General Assembly when they adopted the Report on Justification.  I have in general found articles in New Horizons to be relevant, well written, and informative and in skimming through these article I find that they meet the usual standards.  If you want some reading on the Federal Vision Theology you might want to check them out.
