EWTN News explains: What does it mean that the pope is both head of state and head of the Church?

Unique among world leaders, the pope serves simultaneously as the universal spiritual head of the Catholic Church and as the head of the Holy See, a distinct sovereign entity under international law that serves as the central government of the Catholic Church.

So what do these multiple roles mean in the context of a pope’s day-to-day work as the visible leader of the world’s Catholics?

Andreas Widmer, a former Pontifical Swiss Guard who served St. John Paul II and who now teaches at The Catholic University of America in Washington, D.C., told EWTN News that the papal states once formed a substantial territorial kingdom in central Italy with the pope as its temporal ruler.

Following Italian unification in the 19th century and the loss of most of those lands in 1870, the Church further developed the concept of the Holy See as an enduring international presence independent of extensive territory.

The 1929 Lateran Treaty formalized the creation of Vatican City State — a tiny sovereign territory of approximately 109 acres centered on Vatican Hill — providing the pope with just enough independence to exercise his universal ministry free from external coercion.

“From then on, the pope filled two distinct roles,” Widmer said. “He’s the spiritual head of the Catholic Church, and he’s the head of state of Vatican City — the only absolute sovereign in Europe.”

In principle, the Church could lose the territory of Vatican City and still retain its international juridical personality and diplomatic relations through the Holy See — much as a sovereign could continue to exist and maintain diplomatic relations even without a fixed territorial capital.

“The Church could give up the Vatican and still have the ambassadors, because it’s the Holy See,” Widmer noted. “Anywhere the pope is, there the Holy See is.” This arrangement ensures the “libertas Ecclesiae” — the freedom of the Church.

In addition, the pope’s status as a recognized foreign head of state confers immunities under international law that place him outside ordinary civil obligations of his country of origin, such as the obligation to vote or the payment of taxes.

The pope may still retain citizenship of his home country, in addition to the Vatican citizenship he automatically acquires upon his election as pope.

Andrea Gagliarducci, a Vatican expert and EWTN News contributor, said that this unique position also explains why attempts to treat the pope as a corporate executive in civil lawsuits ultimately fail: As both a sovereign head of state and the institutional embodiment of the Holy See, all relevant immunities apply to him.

The personal immunity of foreign heads of state is a customary principle of international law that guarantees full exemption from criminal, civil, and administrative jurisdiction in another state and covers both official and private acts.

The small territory of Vatican City, in the words of Pope Pius XI, provides “just enough body to keep the soul united,” allowing the successor of Peter the freedom necessary to shepherd the universal Church without being bound by any single nation’s interests.

In practice, the Holy Father focuses primarily on his pastoral and moral leadership. When he addresses questions of war, peace, or human dignity, he does so first and foremost as vicar of Christ.

As Andrea Tornielli of the Vatican Dicastery for Communication has pointed out, the pope in his leadership of the Church invites the world to higher principles of justice and fraternity, while the practical diplomatic machinery of the Holy See operates in service of that mission.

  1. What State was St. Peter the first Pope the head of? And, since the Pope is the Vicar of Christ, where was Jesus’ State?

    • The Vatican State is not a theologically necessary componemt of the Papacy, it is a practically useful one, as it keeps the Pope relatively clear of being strongarmed by the temporal rulers of Rome. Early Church history shows a fair amount of that, including physical threats to the Pope, exile, and the like, from the Roman Emperor on numerous occasions – after the Emperor was Christian. Not that politics or persecution will ever go away completely, but there are advantages to toning down their influence.

        China.

        Danced with wind and danced with fire
        Killed the truth and called the liar
        Bleeding in its mystery when the moon began to fall
        Dreamers are not all they seem
        Sleeping in her silent dream
        She locks it all inside and hides it all away

        China, China
        Calling out to history
        Is that the way it will always be?
        China, China…

  2. This piece unwittingly confirms a bad trend of Francis and Leo: the official papal spokesman says the job of the pope as head of the Church/Christianity is to ‘invite the world to higher principles of justice and fraternity?’ Noooo. It’s to proclaim the gospel and invite people to follow Christ, to repent, convert, etc., especially non-christians, such as muslims. And the article’s author blindly adopts and repeats this sad description.

    • “the article’s author blindly adopts and repeats”

      I’d like to be able to say that’s a peculiar feature of this article, or even this author, but it seems to be an a rather consistent feature of EWTN News of late. They really need fewer credulous stenographers.

  3. If the Papacy and some of our short-sighted Catholic faithful insist on hitching the Church’s wagon to a temporal State like any other run of the mill country, they haven’t considered one reality. That is, when radical Islam fully overruns Europe and take control of governments, culture and society at large, their intention very unmistakably will be to eliminate the Vatican City-State altogether. If the Pope or anyone else think their intentions lie elsewhere, they are fools of the worst order and are ignorant of history and haven’t picked up a newspaper in years (admittedly ‘picking uo a newspaper’ is an anachronism).

    • Romystree :With all due respect, what makes you think that the Pope does not remember that Jesus is the head of the Church? Quite a presumption on your part!

  4. Perhaps it was Divine Providence that made the Vatican a State in 1929. It has given the Pope a place on the world stage equal to that of the most influential and powerful nations. It allows him to speak in parliaments and congress and even the United Nations, and is given the opportunity to address moral issues on the World Stage. It also allows him to weigh in on mediation of belligerent conflicts. I do not understand why some Catholics are bothered by this and think he should stick to strictly Church issues.

  5. James Connor: For the simple reason that when the leaders of our Catholic faith start acting like: kings, prime ministers, presidents, etc they are operating in the realm of politics which has the potential of compromising the very mission of the Church which is to proclaim Christ. We’ve had recent Popes who do NOT proclaim Christ at all times and in fact Francis issued major documents that hardly even made reference to Christ.
