THEOPOLOGETICS PODCAST, Michael Burgos (Trinitarian) debated James Anderson (Oneness) on the topic: "The Son personally preexisted the incarnation with the Father." I must say, this is probably the most useful debate i've heard on this topic. As a matter of fact, I don't think i've ever heard a Christological debate with a topic this focused. Usually, its just "Trinity vs. Oneness" or something along those lines.
Of course, some of my readers will disagree with the theological perspectives of both proponents. However, I think this is a debate that anyone can learn a great deal from. Both men were very well prepared and debated in a cordial fashion. Therefore, I feel that both positions were more than adequately contrasted.
