If you have not read it yet, you must read Peter Leithart’s review of Khaled Anatolios’ defense of “person” language, and what that entails, in the doctrine of the Trinity:
I have touched upon this issue in the past. In particular, I am fascinated by where Barth would stand in the current discussion. It is not easy to say. As I have blogged before — Barth and the “fellowship in the Trinity — he can be appropriated by both sides, those for and against social or personalist models of the Trinity. I also discussed these matters here: “In God, subordination is not deprivation,” which is one of my favorite posts.
