JD Walters has recently posted two more articles in his ongoing series responding to the Dutch Radicals, Hermann Detering, and others who have rejected the authenticity of all of the Pauline letters in the New Testament and the traditional Christian view of Paul. You can read the articles here and here. And I've posted a response to the articles in the comments section of the thread here.
By the way, one of the commenters at JD's blog said that he heard an interview with Craig Keener in which Keener referred to his upcoming Acts commentary as "well over 5000 pages". It was initially nine thousand pages long. At Keener's web site, we're told:
"Craig completed his commentary on Acts and is waiting for editing to be completed (this may take some time--expect it in late 2010 or perhaps 2011; it is rather long)."
