Rupture or reform? The hermeneutics of Vatican II in the writings of Joseph Ratzinger

This paper contains Joseph Ratzinger's ideas on the question of continuity or break of Vatican II with the preceding tradition. The study starts with two keywords "reform" and aggiornamento. Then follows Ratizinger's judgment on the application of the liturgical reform and the reading of the Bible in the Church. And finishes with his thought on the continuity of Gaudium et Spes and Lumen Gentium.
