A companion piece to the interview with Professors Casarella and George, Mark A. Noll, co-author of Is the Reformation Over?: An Evangelical Assessment of Contemporary Roman Catholicism, offers thoughts on how ecumenism between Evangelicals and Catholics and Reformation themes differ depending on geographical location and cultural history as well as how ecumenical discussions should be pursued and perceived. Having taught at both an Evangelical and Catholic institution, Noll discusses how key beliefs of both Evangelical and Roman Catholic thought can benefit the other including how the concepts of priesthood and tradition are understood.
