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."

Father James Martin, a papal contributor to ABC News, said cardinals will be looking for "someone who is holy, someone who is a good evangelizer who can proclaim the gospel and someone who is a good manager."

Any baptized Catholic male is eligible to take Francis' place, but Miles Pattenden, historian of the Catholic Church at Oxford University, said Pietro Parolin, the cardinal secretary of state, and Luis Tagle, the archbishop of Manila in the Philippines, are the main front-runners.

Cardinals told to prepare for 'highest human' responsibility

Cardinal Giovanni Battista Re, the dean of the College of Cardinals, reminded his fellow cardinals on Wednesday that they were about to undertake "an act of the highest human and ecclesial responsibility" in voting for a new pope.

"This is a human act for which every personal consideration must be set aside, keeping in mind and heart only the God of Jesus Christ and the good of the Church and of humanity," Re said in a homily during a Mass in St. Peter's Basilica.

But, he said, the election of a new pontiff also comes at a "difficult and complex turning point in history."

"Today's world expects much from the Church regarding the safeguarding of those fundamental human and spiritual values without which human coexistence will not be better nor bring good to future generations," Re said.
