Pope appoints new Holy See Permanent Observer to UN in New York
Pope Leo XIV has named Archbishop Christophe‑Zakhia El‑Kassis as the Holy See’s new Permanent Observer to the United Nations in New York. Archbishop El‑Kassis, a Lebanese‑born diplomat, previously served as Apostolic Nuncio to the United Arab Emirates and Yemen and as Apostolic Delegate to the Arabian Peninsula. The appointment was announced by the Holy See Press Office and will enable the Holy See to participate in UN General Assembly sessions and other bodies. The new observer will represent the Holy See at the UN headquarters in New York.

Pope Leo XIV appointed Lebanese‑born Archbishop Christophe‑Zakhia El‑Kassis as the Holy See’s new Permanent Observer to the United Nations in New York, where he will represent the Vatican at UN meetings and activities. 1
The Holy See Press Office announced on 25 July 2026 that Pope Leo XIV named Archbishop El‑Kassis to the UN observer post, succeeding Archbishop Gabriele G. Caccia, who was transferred to the United States. 2
The Holy See enjoys permanent observer status at the UN, a position it has held since 6 April 1964. This status grants the Vatican “free access to most meetings and relevant documentation” and allows it to participate in General Assembly deliberations and other UN bodies without voting rights. 3 4
These appointments continue the Vatican’s long‑standing diplomatic engagement with the United Nations, reflecting Pope Leo XIV’s emphasis on multilateral dialogue and global peace initiatives.
How has the Holy See’s UN observer role evolved since 1964?
The Holy See’s role at the United Nations (UN) did not change from “observer” into “full member-state participation,” but it did evolve in practice and—crucially—was later formally clarified and expanded by the UN itself. From 1964 onward, the Holy See moved from an initially invited participation toward an observer status with explicit rights and a larger, better-defined scope of activity in UN work, culminating in the 2004 UN General Assembly resolution on “Participation of the Holy See in the Work of the United Nations.”
The Holy See’s participation in the UN system began earlier than the 1964 UN Headquarters observer arrangement. The Church had already been engaging UN specialized agencies in the post–World War II period, and even where participation existed, it wasn’t always matched with a formalized recognition of the Holy See’s level and range of involvement as a permanent observer.
This is consistent with how the Holy See understands “pontifical legates” (including those acting as observers/delegates): they represent the Roman Pontiff in a stable manner to public authorities at international meetings. In other words, the Holy See’s UN presence is meant to serve the Church’s spiritual mission, while operating within international diplomatic reality.
A key turning point in the UN context was the formal invitation in 1964 by UN Secretary-General U Thant to Pope Paul VI to send a Permanent Observer to the UN. This invitation marked the beginning of a higher level of participation than the earlier pattern of attendance and participation at various meetings and conferences.
The status created by this basis is described as having continued “until 2004” specifically on the footing of the 6 April 1964 invitation letter. In the period after 1964, the Holy See had continuous invitations to attend and make interventions in a wide range of UN meetings and General Assembly sessions—evidence of steady practical engagement, even if the full scope of rights was not yet fully “codified” by a later UN decision.
Another step in the evolution—more “background” but still relevant—came through international legal/diplomatic discussion about how permanent observer missions should be treated.
In particular, the 1975 Conference of Vienna included agreement regarding norms for relations between states and international organizations of a universal character—explicitly proposing norms for permanent observer missions to IGOs and framing them as having equivalency in relevant ways to permanent missions of states (even if not identical in nature).
While this didn’t yet change the UN itself into giving the Holy See full membership, it shows that the Holy See’s observer role was being understood and discussed within a broader framework of diplomatic/international practice—supporting the legitimacy and stability of the “permanent observer” model.
The most decisive evolution described in the available sources is the 2004 UN General Assembly resolution: A/RES/58/314 B, “Participation of the Holy See in the Work of the United Nations,” adopted 1 July 2004.
Before 2004, the sources emphasize that—even with extensive participation—there had been no formalized acknowledgment of the range and level of the Holy See’s permanent observer participation. That “issue was addressed in 2004.”
The 2004 resolution explicitly:
The sources also explain what this increased capacity allowed the Holy See to do at the General Assembly and related UN fora. The expanded capacity was described as allowing the Holy See to:
Importantly, this is framed not as a transformation of the Holy See into a normal member-state, but as a clarification of the parameters of observer participation consistent with its distinct nature.
The evolution above is best understood alongside the Holy See’s internal understanding of what those UN representatives are doing.
The sources stress that the Apostolic Nuncio acting as Permanent Observer (and similar roles) is focused on promoting the Church’s spiritual mission, distinguishing pontifical representatives from UN state-mandated diplomats who gather under the UN’s state-diplomatic framework.
This distinction also helps explain why the UN was careful to speak in terms of “Observer State” participation rights and privileges—allowing meaningful institutional engagement while preserving the Holy See’s identity as something other than an ordinary state actor.
The provided sources treat 2004 as a formal milestone: until 2004 the status rested on the 1964 invitation letter, and then the UN General Assembly formally approved and expanded the parameters of participation.
The sources do not detail later (post-2004) legal changes in the same granular way; however, they do indicate that the Holy See’s UN presence continued as an observer with a valued role—maintaining active participation while safeguarding the stance of universality described in an address from 1989.
Since 1964, the Holy See’s UN observer role evolved in three main ways, as reflected in the available Catholic scholarly and documentary sources:
From 1964 to 2004, the Holy See’s UN presence moved from being grounded primarily in a formal invitation and ongoing “invited participation” toward a more institutionally explicit observer role. The 2004 resolution is the clearest inflection point: it translated long-standing practice into formal participation parameters, enabling the Holy See to contribute more directly while remaining an observer rather than a full member-state.
