Scanned this work last night. As to the in-fighting among dubs I have seen many similar things happen in the congregations over the years. As to his theological diatribe, can't buy much of it. All in all it seems that the real purpose of his writings is to elevate his own position as an important one. Didn't count the number of "I's" and "I've done", but I came away thinking that the fellow, however well meaning he is, was on a "ME" trip.
Just my non-biblical scholarly opinion, worth perhaps only one lepta.
