Professor Melloni is a major contributor to the work on the Second Vatican Council led and promoted by the so-called “scuola di Bologna”. Its research mainly focused on the discontinuity hermeneutics, which differs from the official position of the Church according to a few Italian journalists. Pope Benedict XVI in fact states: "Discontinuity hermeneutics is likely to create an abrupt separation between the pre-conciliar and post-conciliar church". On the other hand, scholars related to the “scuola di Bologna” highlight the fact that the Pope's opinion does not centre exclusively on continuity. According to Melloni it is impossible to read the Pope's words as a mere post-conciliar repentance.
