Vatican Appoints New Ambassador to US Amid Rising Diplomatic Tensions

Pope Leo has selected Italian Archbishop Gabriele Caccia as the Vatican's new ambassador to the United States. The 68-year-old diplomat previously served in the Philippines and at the United Nations, and will take over during a period of strained Vatican-U.S. relations.

VATICAN CITY – Pope Leo announced Saturday his selection of Italian Archbishop Gabriele Caccia as the Vatican’s new ambassador to the United States, choosing a seasoned diplomat who previously navigated challenging political waters in the Philippines.

The 68-year-old Caccia spent two years representing the Holy See in Manila before taking on the role of Vatican ambassador to the United Nations in 2020. His new assignment comes at a time when Vatican-U.S. relations have grown tense over foreign policy disagreements.

The appointment follows recent Vatican condemnation of U.S.-Israeli military actions against Iran. Cardinal Pietro Parolin, the Vatican’s chief diplomat, stated Wednesday that such military operations violated international law.

Pope Leo, who is the first American pontiff, has also publicly criticized several of President Trump’s conservative policies, calling the administration’s immigration enforcement measures “inhuman” as they have disrupted communities nationwide.

Caccia brings extensive diplomatic experience to Washington, where he’s regarded as one of the Vatican’s most skilled foreign service officers. His arrival coincides with growing criticism of the Trump administration from American Catholic bishops.

The new ambassador will take over from Cardinal Christophe Pierre, 80, who is stepping down after serving as the Vatican’s U.S. representative since 2016.

Earlier this year, three prominent American cardinals publicly questioned the nation’s foreign policy direction, expressing concern about America’s “moral role in confronting evil around the world.”

During his tenure in Manila, Caccia became known for defusing conflicts between local Catholic leadership and then-President Rodrigo Duterte, who regularly launched verbal attacks against Church officials during public addresses.

Duterte, who completed his term in 2022, currently faces proceedings at The Hague related to killings that occurred during his anti-drug campaign.

The Washington posting ranks among the Vatican’s most significant diplomatic positions worldwide, as the Holy See operates approximately 110 embassies globally. The ambassador must advocate for Church interests with the White House, and Vatican representatives have historically challenged various American administrations’ policies.

Beyond international diplomacy, the Vatican’s U.S. ambassador holds considerable influence within America’s Catholic Church. The position includes recommending American clergy for bishop appointments to the Pope, affecting the spiritual lives of the nation’s 72 million Catholics.

A Milan native, Caccia previously served as Vatican ambassador to Lebanon and held a senior position for seven years in the Vatican’s influential Secretariat of State.

Formal diplomatic ties between the Vatican and United States began in 1984 during Ronald Reagan’s presidency. Caccia will be the first Vatican ambassador to Washington who previously served at the United Nations.
