The Holy See has formal diplomatic relations with almost all states of the world and with international organizations including the United Nations (UN), where it holds Permanent Observer status. Its diplomacy considers the UN as one of the most important agents in international affairs.
In the article, we clarify the Holy See's role as a Permanent Observer and its views on international cooperation before the Second Vatican Council. We then shed light on the leading principles and aims of its diplomacy at the UN as verbalized through the papal addresses to the General Assembly, letters to UN secretaries general, and various messages.
Finally, we describe the Holy See's position in the long-lasting debate over UN reform.
