Archbishop Gabriele Caccia, newly appointed apostolic nuncio to the United States by Pope Leo XIV, takes up his diplomatic post amid tensions with the U.S. administration.
Pope Pope Leo XIV has appointed Archbishop Gabriele Caccia as the Holy See’s new apostolic nuncio (ambassador) to the United States, a senior diplomatic role that comes at a time of strained relations with the Trump administration.
Archbishop Caccia, 68, succeeds Christophe Pierre, who retired after a decade as nuncio in Washington. Caccia had been serving as the Vatican’s permanent observer to the United Nations in New York since 2019 and brings extensive diplomatic experience from previous posts in Lebanon and the Philippines.
Strategic Diplomatic Move
The appointment underscores the importance of Vatican‑U.S. relations amid ongoing disagreements over U.S. foreign and domestic policies, notably President Donald Trump’s military actions in Iran, immigration enforcement, and global conflict responses.

Pope Leo XIV, the first American pope, has expressed concern over conflict and the treatment of migrants, urging peaceful dialogue over force while maintaining respectful engagement with the U.S. government.
Role and Reception
As apostolic nuncio, Archbishop Caccia will serve as the Vatican’s chief diplomatic representative to both the U.S. government and the Catholic Church in the United States, including participation in the selection process for bishops.
The appointment was welcomed by Catholic leaders, including Archbishop Paul S. Coakley, president of the United States Conference of Catholic Bishops, who praised the new nuncio’s role in fostering unity and collaboration between Rome and the American Church.
Archbishop Caccia described his new mission as one “at the service of communion and peace,” marking a pivotal moment for the Vatican’s diplomatic engagement during the 250th anniversary of U.S. independence.
Further details on his official start date and inaugural engagements in Washington are expected in the coming weeks.
