The early leaders of the postwar evangelical coalition were for the most part conservative Calvinists, and it was mostly understood that there would not be a swing away from that theology. But over time we have developed into much more diverse groups of people, and the hegemony of paleo-Calvinism has dissolved. It will be hard for those who think that is a good thing to live in harmony with those who think it is a major disaster. In order for Olson's call for peaceful relations to succeed, two things have to happen. First, we must become more modest in our claims.
Theology is an unfinished task, and all of our efforts at interpretation are limited in insight.
There is more to be known about God than any of us presently knows. Second, we need to look to the future as well as the past. May God grant that we continue to grow as hearers of the Word and enlarge our vision of the truth through interaction with each other. For my part, I value the work of R. C. Sproul and wish him godspeed.
