For me, Kreeft is most moving when talking about the need for Catholics and Protestants to clear away the pernicious stereotypes and caricatures that have built up over the centuries. In order to move towards reunion, he rightly urges us to really listen to each other with more depth, patience, and humility (72). When this happens, we can discover deeper levels of mutual understanding and better remember that, despite the differences, we still ultimately belong to the same Body of Christ. We may even find echoes of perspectives that we hold dear in unexpected places. Now of course, it’s true that merely listening to each other better (as necessary as that is) won’t automatically dissolve the theological issues that continue to divide Catholics and Protestants. But, Kreeft dares to hope that as we better understand one another, and seek together to follow Christ more closely, we may be surprised to find eventual healing for these areas of division (80). As evidence of this, he points to the joint Catholic-Lutheran Decree on Justification, which Kreeft is convinced shows that, “The single greatest obstacle to reunion, by far the most important religious difference between Protestants and Catholics, has essentially been overcome” (17).
The latter part of the book contains a number of longer chapters exploring some of the central issues that stand in the way of reunion, including Catholic doctrines about Mary, the relationship between Scripture and Tradition, and matters of ecclesiology. In these chapters, as in the earlier parts of the book, Kreeft’s style is personal and aimed at making the subject matter understandable for the non-specialists among us. I’ll admit that I wasn’t persuaded by all of his arguments, but I incline to think that that isn’t especially the point. If a necessary step towards ecumenical reunion is better understanding each other, then Protestants like me must value our Catholic friends enough to spend time honestly letting them explain how the issues look from their point of view, with the presuppositions they bring to the table. I think that is one of the best ways to get past simplistic misunderstandings about how the “other side” practices their faith.
