I have been tracking Yung Suk Kim's forthcoming Christ's Body in Corinth:The Politics of a Metaphor for some time now.
Here is the blurb: Plus check out the cool cover! »
Yung Suk Kim takes up the language of "body" that infuses 1 Corinthians, Paul's most complicated letter, and the letter that provides us the most information, and poses the sharpest questions, about social realities in the early church. Kim argues against the view that in speaking of the church as Christ's body Paul seeks to emphasize unity and the social boundary. Against the conventional rhetoric of the "body politic" in Greco-Roman philosophy, Kim argues that Paul seeks rather to nourish the vitality of a diverse community and to criticize the ideology of a powerful in-group in Corinth, a message of
particular importance for contemporary global Christianity.
In addition, Kim has a really nice webpage that can be found here.
