It is occasionally said of Edward Schillebeeckx that he is a difficult theologian to understand because in the last analysis he does not have a theology! Instead, he is thought to have produced two, three, or more, quite distinct theologies, whose characteristics depend on the kinds of philosophical equipment he has marshalled in order to give conceptual embodiment to his theological convictions.
Over the past five decades, Schillebeeckx has published about four hundred and seventy theological studies. A perusal of these divulges that at different stages his writings have freely borrowed philosophical ideas from such diverse contexts as phenomenology, existentialism, Anglo-American-Scandinavian analytical philosophy, structural linguistics, semiotics, neo-Marxist critical theories of society, and twentieth-century revivals of Thomism—a list by no means exhaustive.
A survey of his publications further uncovers that for a period of about nine years, from 1963 to 1974, he did not write a single book. These years, particularly from 1966 onwards, were devoted to a determined study of hermeneutics and biblical exegesis as a preparation for interpreting Christian faith in a new way. In 1974, at the end of this incubatory period, he published Jesus: An Experiment in Christology, the monograph in which he effectively gave notice that he had radically changed his theological method. From the mid-1940s to the mid-1960s, he had employed a method which took classical theological theories and texts as its point of departure. With the book Jesus, however, references to patristic, medieval, and papal documents have to a large extent been put aside in favour of an avowedly hermeneutical method, which is dependent on a bountiful array of exegetical data and which seeks to set past and contemporary human experiences in a mutually critical and interpretative relationship with each other.
