The article presents the most important aspects of the interventions made by the representatives of the Holy See before the United Nations dealing with the question of religious freedom, in the seven years since Benedict XVI was called to the Papal throne. In many parts of the World, difficulties with regard to religious freedom have increased or acquired new forms. The interventions are related to those questions under debate in each case and in the circumstances of that given moment. Nevertheless, they denote a remarkable coherency and help to understand how the pontifical diplomacy has promoted the right to religious freedom between 2005 and 2012, and express at the level of international relations the thoughts and priorities of Benedict XVI as head of the Catholic Church.
