Adam Neder's book Participation in Christ: An Entry in Karl Barth’s Church Dogmatics, has just been reviewed by the Center for Barth Studies at Princeton. The review is a very good one, which highlights the strength's of Neder's argument of "participation in Christ" as the foci of Barth's "Church Dogmatics" as a whole. I am on my way to reading this book and when I do I will post a review of my own. I recommend that anyone interested in Karl Barth's theology take a look at Adam Neder's book.
Der Evangelische Theologe has also posted a link to this review.
