Pope Leo XIV calls for end to wars in Ukraine, Gaza

Pope Leo XIV was elected as the Catholic Church's 267th leader on Thursday.

The temporary chimney atop the Sistine Chapel released a plume of white smoke on Thursday evening local time, signaling that the 133 cardinals working inside had reached a two-thirds majority to elect a new pope for the Catholic Church.

American Cardinal Robert Prevost was shortly thereafter announced as the 267th pontiff. He chose the name Leo XIV, a senior cardinal deacon announced.

The 69-year-old Chicago native is the first American pope and is seen as a diplomat in the church.

"This is the first greeting of the risen Christ. May the peace be with you," Leo said in Italian in his first remarks as pope. "This is the peace of the risen Christ."

"As an Augustinian Catholic institution, we celebrate this significant day for our University community and the global Church," the Rev. Peter Donohue, the university's president, said in a statement Thursday. "Villanova, built on the teachings of St. Augustine, has always been grounded in advancing a deeper understanding of the fundamental relationship between faith and reason -- between spirituality and wisdom. With today's election of His Holiness, Pope Leo XIV, I cannot help but reflect on what his Augustinian papacy will mean to our University community and our world. Known for his humility, gentle spirit, prudence and warmth, Pope Leo XIV's leadership offers an opportunity to reaffirm our commitment to our educational mission."
