The narratives and responses were all pretty interesting. My favorite set was the first, between the Baptist who became Eastern Orthodox and a Baptist seminary professor. Brad Gregory’s response to the Catholic convert to evangelicalism was quite challenging and used a lot of examples from the Reformation period, but he was more successful in pointing out the challenges that disunity poses to Protestants’ claims than in making a compelling case for Catholicism.
I would have liked to see the rejoinders go into more depth in responding to the responses. Overall, it was an informative and readable book.
