Here is the historic discourse of Benedict XVI from 22 December 2005 to the Roman curia, the first year of his pontificate.
He places Vatican II in its proper context of the perennial dialogue between faith and reason. A dynamic fidelity is sought and needed to respond to the demands of our time, as required in every time and circumstance.
The proper "hermeneutic" is the one that does not break fidelity. The only proper hermeneutic is a faithful hermeneutic. There was a hermeneutic of discontinuity which was wrong and harmful, and the hermeneutic of reform in continuity with the Church before and after which is one and the same: one, holy, catholic and apostolic.
