This book has been needed for some time. If America has ever been a "Christian nation," it has certainly never been a Catholic nation. In fact, "Christian" by definition (for many Americans) excludes Catholics. (It is still common to hear evangelicals say, "I was Catholic before I became a Christian.")
Morris sheds much light on the hostility and suspicion that Catholics in America have faced. He also illustrates in a masterful way how Catholics have attempted to find a way between the desire for acceptance by the larger, Protestant culture and the desire to retain a sense of Catholic identity. This latter stance has sadly resulted in various forms of isolationism and is characterized by a failure on the part of Catholics to evangelize American culture.
Morris writes clearly and avoids unnecessary Catholic jargon. His insights are often penetrating. Throughout most of the book Morris is fair to various perspectives within American Catholic culture.
I consider this text to be "required reading" for religious studies students and students of theology; it is also highly recommended to anyone who wishes to understand the role of Catholicism in American public life.
Nevertheless, the following omissions make this a less than perfect book: (1) He limits his discussion of Catholicism to the Latin (Roman) Rite; (2) there is a curious silence concerning the questions "what is Catholicism?" or "how does Catholicism differ from Protestantism?"; (3) despite the fact that a good third of the book is devoted to events since the Second Vatican Council (1962-1965) and the fact that Morris draws from a variety of theological points of view, he fails to address the Church's own self-understanding as articulated in the documents of Vatican II: communio ecclesiology.
EASTERN CATHOLICS. While Morris duly notes the insensitivity of Irish-American bishops toward Italians, Poles, Germans, and other ethnic groups, there is no mention of the conflict between these bishops and Catholics of other rites (Byzantines, et al). Nor is there mention of how the Irish-American bishops lobbied Rome to prevent Eastern Catholic bishops from ordaining married men (a discipline that is still in place in this country).
WHAT IS CATHOLICISM? Being Catholic, Morris writes as an "insider" and this provides for a richness and depth that would be lacking were he an agnostic or a Christian of another denomination. On the other hand, Morris fails to address many of the fundamental claims of the Catholic Church: her origin as from Jesus Christ (and hence, her claim of universality); the presence of the Church in the world as the continuing presence of Christ for all of humanity; the sacraments of the Church as mediating the love of God in Christ to the world.
Put another way, Morris fails -- sometimes at critical points -- to allow his narrative to be shaped by theology and thus gives a secular, sociological reading of the Church.
I can't recall any statement by Morris concerning Catholic doctrine that was "wrong," but there are numerous points where a better explanation of Catholic theology would have provided the reader with more understanding.
For example, when Morris discusses the encyclical "The Splendor of Truth" and John Paul II's insistence that some actions are always and everywhere wrong (intrinsically evil), Morris says that John Paul II places contracepting couples in the same category as "Hitler and Pol Pot" (p. 367).
Of course, the Pope does no such thing. What John Paul does insist upon is the fact that some actions can never include give glory to God: murder, abortion, theft, and yes, contraception. The Pope is wise enough to recognize the difference between objectively evil actions and one's subjective responsibility for those actions. Morris should have known better than to accuse the Pope - renowned for his Christian personalism - of falling into a crude legalism that equates gravely sinful matter with personal guilt/culpability.
COMMUNIO ECCLESIOLOGY. One rightly gets a sense from Morris that Catholicism since the Second Vatican Council has been interpreted by the majority of Catholics (clerical and lay) through two discrete lenses: liberal or conservative, democratic or authoritarian, the Church as the "People of God" or the Church as hierarchical institution. Both perspectives have an element of the whole truth in them. The difficulty arises (as it does continuously) when people insist on emphasizing one element to the exclusion of the other.
Thus we find some "liberals" questioning whether or not bishops are really part of the Church and "conservatives" resorting to conspiracy theories to explain why the Pope allows (gasp!) female altar servers. It is sad phenomenon that has originated in a selective reading of the documents of Vatican II, especially "Lumen Gentium" (On the Church).
Morris correctly notes that the Fathers of the Second Vatican Council placed the Mystery of the Church at the forefront of their discussion. It is only after discussing the sheer gratuitousness of God reaching down to save humanity in Christ and continuing this presence through his body, the Church, that the themes of People of God and Hierarchy are broached. The Church's reason for being is to put all of humanity (indeed, the entire cosmos) in touch with, in intimate communion with the God-who-is-love.
So long as one approaches the Church in terms of power and control versus love and service, one will forever misunderstand her. Sadly, Morris fails to grasp the importance of the Church as communion and it negatively affects his discussion of topics such as women's ordination, moral theology, the role of the Pope, etc.
Other books that might help thoughtful readers get to the essence of Catholicism include Alan Schreck's "Catholic and Christian" (very accessible) and David Schindler's "Heart of the World, Center of the Church" (a more academic text, but one that is richly rewarding - especially for understanding the nature of the Church in the modern world).
