In light of recent ecumenical discussions and achievements, many are asking to what extent historic theological divisions between Catholics and Protestants have now been overcome. This essay approaches this question by examining the recent study by Mark Noll and Carolyn Nystrom entitled Is The Reformation Over? An Evangelical Assessment of Contemporary Roman Catholicism. The present essay argues that while much progress has been made in the dialogue between Roman Catholics and Protestants in general and evangelicals in particular, issues of ecclesiology will continue to divide the communions for the foreseeable future, and that these issues resist resolution precisely because they are ultimately Christological as well as ecclesiological. This essay attempts to shed light on these Christological and ecclesiological differences.
