The idea of the genetic unity of all mankind is an integral part of Christian teaching. The purpose of this brief survey is to illustrate its role within the Greek patristic tradition, and then to point to a few examples from modern science which lend support to this ancient idea.

In lieu of an abstract, here is a brief excerpt of the content:156 BOOK REVIEWS of theological method in Aquinas (p. 193; see also pp. 57 and 173). But this is not sufficient. Farthing should have acknowledged that Biel's recurrent critique of the supposed ' positive ' use of reason in Aquinas is beside the point and that, by thinking that Thomas is trying to ' demonstrate ' the faith, Biel has carelessly dismissed much that is interesting and valuable in (...) Aquinas. By bringing Biel's error to the fore, Farthing would have made clear to the reader that in this crucial respect, the dialogue between these two thinkers has completely broken down. University of Notre Dame Notre Dame, Indiana JOSEPH WAWRYKOW The Reshaping of Catholicism: Current Challenges in the Theology of Church. By AVERY DULLES. San Francisco: Harper & Row, 1988. Pp. 276. $19.95 (doth). Each of Dulles's twelve articles commends itself no less as a chapter in this collection than when it first appeared separately between 1984 and the end of 1987. In ensemble, " they give," Dulles remarks in his Preface, " a fair sampling of the issues the Catholic Church has had to face in the two decades since the Council." Whatever the leading Catholic ecclesiologist in America has to say about specific problems in Church renewal deserves careful attention. A positive general evaluation of the book is all hut a foregone conclusion. Still, a review can perform that opening survey of contents that will lend precision to a reader's anticipation of what the author has singled out as the current challenges. Four chapters take up the task of interpreting the texts of Vatican II, not as a species of source-criticism but in light of post-conciliar difficulties. Chapters 2 ("The Basic Teaching of Vatican II "), 5 ("Vatican II and the Recovery of Tradition"), and 8 ("Vatican II and the Purpose of the Church") emerge from a situation of divided opinion. They also apply the Council's teaching as a solution. Chapter 7 ("The Church and Communications") likewise engages conciliar texts, along a more speculative line. Chapter 1 ("American Impressions of the Council") joins with 2 in opening the book at a somewhat more popular level. The other chapters employ conciliar teaching to formulate theological answers to some important questions. These are questions which trouble not only the hierarchy and the theologians but also ordinary BOOK REVIEWS 157 members of the Church, as they come to terms with the Church's renewed self-understanding. Chapter 3 (" The Emerging World Church and the Pluralism of Cultures") picks up where Karl Rahner's wellknown address at the Weston School of Theology in 1979 left off. Dulles accepts Rahner's argument that Vatican II achieved the first official self-actualization of Catholicism as a world church. Taking the resulting problem of inculturation as the current phase in the relation between Christianity and culture, Dulles specifies the relation between two cultures as "cultural reciprocity." He leaves behind the simple, familiar contrast between classicism and a non-normative concept of culture. His ecumenical research enters into Chapter 4 ("The Meaning of Catholicism: Adventures of an Idea "), which places Vatican II in the context of two centuries of Protestant-Catholic discussion on the essence or basic idea of Catholicism. Intra-Catholic pluralism turning into opposition underlies most of the hook, hut Chapters 5 and 6 ("Authority and Conscience: Two Needed Voices") treat two such polarizations thematically. In 5 Dulles finds Dei Verbum open to an understanding of tradition as the handing on from generation to generation of the " tacit knowledge " whose content is the lived awareness of the God of Jesus Christ. Chapter 6 does not admit a second, alternative magisterium, hut it does situate hier· archical teaching amid the several sources of authority accepted by Catholicism-Scripture, tradition, the whole People of God, and theologians along with the hierarchy. And, in the formation of personal judgments and decisions, conscience has its own authority. A theology of communication follows from each of five models of the Church. Chapter 7 shows how this, in turn, implies a distinct approach to evangelization, use of mass media, and episcopal and papal teaching. Chapters 8 and 9 {"The Church, Society, and Politics") discuss the tensions inherent in the Church's mission... (shrink)
