Justin Brierly, host of the UK program Unbelievable, recently hosted two discussions between James White (Calvinist) and Roger and Faith Forster (Arminians). Rumor has it that that Greg Boyd was originally supposed to participate too, but was unable to make it. (HT: darinhouston)

I have listened to the first episode, but not the second. The debate was pretty good. James White was his typical self (long winded and imputing incorrect positions to his opponents). The Forsters capably represented the Arminian view. I was particularly impressed with Faith Forster, who was not afraid of calling White out on his usual tactics.
