This study is an introduction to Catholic theology designed both for the theological student and for the general reader willing to make a certain effort. After introducingthe idea of theology and the virtues desirable in the budding theologian, the bulk of the book falls into five sections: 1. the role of philosophy in theology, 2. the use of the Bible in theology, 3. the resources of tradition for theology, 4. two 'aids to discernment in theology'- experience, and the Church's magisterium, 5. a short history of Catholictheology from the New Testament to the present day. The conclusion considers the features of pluralism and unity which should typify Catholic theology as a whole and suggests how unity may avoid becoming uniformity without pluralism falling into anarchy.
