The bishop of Cleveland will become the new leader of the Archdiocese of Philadelphia, the Vatican announced Thursday, making him the first Hispanic archbishop to lead the region’s 1.3 million-member flock.

A news conference was scheduled Thursday morning to introduce Nelson Perez. He will succeed Archbishop Charles Chaput, a conservative culture warrior who will step down after turning 75 last year, the traditional retirement age for Catholic bishops.

Perez, 58, is coming home in a way, after attending the diocesan seminary in Philadelphia in the 1980s and serving in a number of Philadelphia parishes before being named as an auxiliary bishop in Rockville Centre, New York and then bishop of Cleveland in 2017.

In a tweet, Perez said “it is with great joy tinged with a sense of sadness that I accept the appointment - joy that I will be returning to serve @ArchPhilly, sadness in that I will be leaving @DIOCESEofCLE.”

Chaput, for his part, faced a difficult task trying to restore credibility in the Philadelphia hierarchy following revelations of clergy sexual abuse and cover-up by his predecessors that were revealed in 2005 and 2011 grand jury investigations.

Appointed in 2011, Chaput was very much in favor under conservative Pope John Paul II and Pope Benedict XVI, named to participate in important Vatican missions even while being denied the cardinal's red hat that his predecessors enjoyed.

Chaput, a member of the Cappuchin order, has denied he is a critic of Pope Francis, and he hosted the Argentine pope when he visited Philadelphia in 2015 for a big family rally. The visit, including a Mass that drew a reported 1 million people, gave Francis a much more positive impression of the U.S. than he had going into the trip.

But the two clashed. After Francis opened the door to letting divorced and civilly remarried Catholics receive Communion in 2016, Chaput closed the door in Philadelphia by saying they must abstain from sex if they want the sacrament.

Chaput was also one several U.S. bishops who praised the integrity of leading Francis critic, Archbishop Carlo Maria Vigano. The former Vatican ambassador to the U.S. in 2018 called for Francis to resign for allegedly rehabilitating ex-Cardinal Theodore McCarrick, alleging he was part of a two-decade conspiracy of cover-up.

In his letter, Vigano implied Francis opposed Chaput's conservativism, quoting the pope as telling him in 2013 that U.S. bishops must not be ideologically driven, “they must not be right-wing like the archbishop of Philadelphia."

Francis has said he doesn't remember details of the 2013 meeting.

While Francis quickly accepted Chaput’s resignation, this week he formally told another 75-year-old prelate to stay on indefinitely. Cardinal Christoph Schoenborn, the archbishop of Vienna, is a strong Francis supporter and helped draft the final document at the controversial Amazon Synod, where bishops called for married priests in the Amazon.
