Specifically, he focuses on the line of argument that I first developed in my contribution to Universal Salvation? The Current Debate--an argument which John Kronen and I expand on and situate into a broader line of argument in God's Final Victory. Kimel also considers Tom Talbott's thinking on the subject, locating his reflections within his own broadly (eclectically) Orthodox context. He sums up his reactions as follows:
I confess that I am reluctant to speak of a guarantee of universal salvation, as Reitan does; but Talbott’s and Reitan’s arguments should encourage us in a confident and robust hope for the salvation of every human being. God does not need to force anyone to repent of his sins and embrace heaven. Precisely because we are created for him, all he needs to do is to allow us to experience the hell that we think we want. Suffering, divine grace, and the prayers of the Church will do the rest.
The whole piece is nicely done and worth reading for anyone interested in the topic.
