Asbury Theological Seminary recorded recent a biblical studies seminar on the New Perspective on Paul. The primary faculty participants were Joseph Dongell, Ben Witherington, and Craig Keener.
The session flows through the two following recordings. The New Perspective discussion starts at approximately the 4:00-mark in the first recording.
Update: Unfortunately, the video embedding I attempted previously in this post didn’t work out as it had looked to. The links to the relevant pages on Vimeo’s website are:
