Pope Leo XVI will officially inaugurate his papacy with Mass in St. Peter’s Square May 18.

A group of House Republicans have reportedly expressed opposition to eliminating Planned Parenthood’s federal funding through the budget reconciliation process.

Where Christians are “mocked, opposed, despised or at best tolerated and pitied” is where the Catholic Church’s “missionary outreach is most desperately needed,” Pope Leo XIV said in his first homily as leader of the world’s 1.4 billion Catholics.

The head of the Midwestern Augustinian province that Pope Leo XIV once led called the new pope’s election “moment of profound significance — not only as the first pope from the United States, but also as the first Augustinian to be elected pontiff.”

Key dates in the life and ministry of Pope Leo XIV, elected May 8, 2025, as the 266th successor to St. Peter.

Pope Leo, 69, formerly Cardinal Robert F. Prevost, is the first pope from the United States. He assumes the chair of Peter with multifaceted leadership experience: He grew up in the Midwest, graduated from Augustinian-run Villanova University in 1977 with a math degree, ministered as a bishop in Peru, and led the Vatican dicastery that helps appoint, form and retire bishops.

President Donald Trump on May 8 congratulated Cardinal Robert F. Prevost, the Chicago-born prefect of the Dicastery for Bishops under Pope Francis, who was elected the 267th pope the same day, taking the name Pope Leo XIV.

Even before he stepped out on the balcony of St. Peter’s Basilica and spoke May 8, Pope Leo XIV’s choice of a name was a powerful statement.

Cardinal Robert F. Prevost has selected the name Pope Leo XIV, an apparent nod to Pope Leo XIII, who deserves to be called the founding father of Catholic social doctrine in modern times, with his encyclical “Rerum Novarum” as its foundational document.
