Limited Atonement with David Allen, Ecclesiastical Textism with Robert Truelove

First Dividing Line back from a fierce ten day battle with the flu, so we went mega-length, two full hours.  First 75 minutes we discussed the atonement and theology in general, starting to listen to comments made by Dr. David Allen of Southwestern Baptist Theological Seminary wherein he described limited atonement as a "doctrine looking for a text."  It was not difficult debunking that claim, to be sure. But then we moved over in the last 45 minutes to Robert Truelove's video on the ecclesiastical text, once again asking---ok, so?  What does this actually accomplish?  How does it answer questions?
