American evangelicalism has recently experienced a new openness to Roman Catholicism, and many evangelicals, both famous and ordinary, have joined the Catholic Church or are considering the possibility. This book helps evangelicals who are exploring Catholicism to sort out the kind of concerns that typically come up in discerning whether to enter into the full communion of the Catholic Church. In simple language, it explains many theological misunderstandings that evangelicals often have about Catholicism and suggests the kind of practical steps many take to enter the Catholic Church. The book frames evangelicals becoming Roman Catholic as a kind of "paradigm shift" involving the buildup of anomalies about evangelicalism, a crisis of the evangelical paradigm, a paradigm revolution, and the consolidation of the new Catholic paradigm. It will be useful for both evangelicals interested in pursuing and understanding Catholicism and Catholic pastoral workers seeking to help evangelical seekers who come to them.
