I recently found a new free online journal.  The Journal of Greco-Roman Christianity and Judaism.    This seems to be one of the best free online journals available.  Print editions come from Sheffield and Stanley Porter is the chief editor.   There are articles dating back to 2000, with studies written by scholars such as Porter, Craig Keener, Craig Evans and Michael Knowles.  There is a section with book reviews as well.   I read Porter’s article “Paul’s Bible, His Education and His Access to the Scriptures of Israel.”  It was quite infromative.  Check it out here.
