“The pope normally speaks as a head of the Church,” papal expert Father Roberto Regoli told EWTN News.

When the pope speaks out on matters of war and peace, is he doing so as a religious authority or a political leader? A U.S. diplomat and a Vatican official recently expressed contrasting views on the question.

According to the New York Times last week, U.S. ambassador to the Holy See Brian Burch argued that when Pope Leo spoke out against the war in Iran, “he was not doing so as the leader of the Roman Catholic Church, the vicar of Christ.”

“When the pope acts as the sovereign leader of the Holy See, he is coequal with world leaders,” Burch is quoted as telling the NYT in an interview published online July 9.

A rare op-ed from the editorial director of Vatican communications, Andrea Tornielli, appeared just days later, stating that “even when he speaks about war and peace … the successor of Peter remains, above all, a spiritual leader.”

While the Vatican News editorial did not mention Burch by name, it addressed the ambassador’s argument in the NYT interview.

“Any glorification or exaggeration of the pope’s role as head of state, any emphasis on the importance of this role, is therefore misleading because it comes at the expense of his one true mission as universal shepherd,” Tornielli wrote.

A spokeswoman for Burch declined to comment.

Expert weighs in

Father Roberto Regoli, an expert on papal history and diplomacy from the 19th to 21st centuries, explained that while the pope is the head of a state, “it is just functional to his personal service as a Church leader.”

“Vatican State is an enclave state … it is functional for the spiritual mission of the popes,” Regoli told EWTN News. “The pope normally speaks as a head of the Church.”

In the Vatican News editorial, Tornielli pointed to the 1929 Lateran Pacts, an agreement that resolved the issue of the temporal power of popes and gave the pope a small territory — less than 110 acres — but said that “does not mean that he acts or speaks as a politician when addressing issues concerning the affairs of humanity.”

Tornielli quoted St. Paul VI, who, in an address to the United Nations General Assembly in 1965, said, referring to himself, that “he is your brother, and even one of the least among you who represent sovereign states, since he possesses — if you choose to consider us from this point of view — only a tiny and practically symbolic temporal sovereignty: the minimum needed in order to be free to exercise his spiritual mission and to assure those who deal with him that he is independent of any sovereignty of this world. He has no temporal power, no ambition to enter into competition with you.”

Regoli noted that the political power of popes was different in the past, such as in the time of the Papal States. Being the head of a state today “is just functional to his personal service as a Church leader” to maintain his independence.

As the sovereign of an independent city-state, the pope has interactions with other states and multilateral institutions via apostolic nuncios and other delegates, who represent him to both the local Church and the state, Regoli said.

He added that these “diplomatic structures are in the function of papal politics,” which are “ecclesiastical politics” — that is, about the Church’s internal government.

Pope Leo himself, at the beginning of a speech to members of the Spanish Parliament in Madrid on June 8, explained in what capacity he addressed the politicians and the role of the Holy See on the international stage.

“I come before you,” he said, “as the bishop of Rome and shepherd of the Catholic Church, aware that the mission entrusted to the successor of the apostle Peter, as the principle and foundation of the unity of the bishops and the faithful, places the Holy See, in a special way, in dialogue with peoples and with states.”
