Some forty years on from the great events of the Second Vatican Council, there is still much debate about the interpretation of the Council and its documents. In recent years there has been what might be termed a hermeneutical project: to develop an understanding of the complex processes involved in the genesis of the texts and to explore the interactions of the various individuals and groups that helped to shape the Council. What has emerged is a view of the Council (...) as something organic and dynamic. This article seeks to outline the questions that this hermeneutical project has raised; such as the various sources that can be used to interpret the Council, the impact of various theological strands of tradition present at the Council, the authorship of the texts and the methodologies adopted by the Council. It also provides a review of the work that has taken place with this project, especially in the last ten years or so. (shrink)
