This is a very important book on Catholic - Protestant relationship in America. For many decades in America, Protestant Christians have looked down on Catholic Christians. A part of this was due to ignorance about Catholicism. A part of this was due to past historical experiences. Despite the years of being looked down upon, Catholics in America managed to win the respect of American Protestants. How did they do it? Peter Fields argues that it was through persistent and systematic Catholic opposition to abortion, pre-marital sex, and homosexuality that American Catholic Christians managed to win the respect of American Protestant Christians. This expert study is very readable and easy to understand. All readers of every age will learn about an important social phenomenon in American history by reading this book.
