I bought this book with the hope of reading how top contemporary Protestant scholars address the issue of ecclesiology espoused by Rome and the Orthodox. It left me sadly disappointed. The chapter that addresses the four marks of the church defined in the nicene creed did not attempt to reconcile Protestant perceptions of those terms with the historical understanding of the council fathers. None dealt substantially with Eph 5:32. I was further saddened that one author criticized the piety of Catholics on the basis of his understanding rather than taking the time to just ask some of them why they were doing it. All guns trained against Catholicism while the Eastern Orthodox hold nearly identical views on ecclesiology. Perhaps someday a book with less rhetoric and polemic will attempt to address issues that build understanding rather than polarizing divisiveness.
