This is a fairly interesting compilation of essays, written by Lutheran and Episcopalians, on an important ecumenical concordat from the 90s aimed at full communion between the churches. Sadly, the work done here has been washed away in the flood of wider ecclesial and doctrinal disarray. Ephraim Radner and David Yeago's chapters are particularly memorable and insightful. Many essays overlap, which can be tiring, but they serve to unpack the Concordat (included in an appendix in the back) and reiterate the major themes of this endeavor.
