WASHINGTON —  The appointment of Archbishop Wilton Gregory to succeed Cardinal Donald Wuerl brings an end to one of the most anticipated and drawn out episcopal appointment processes in recent memory.

Archbishop Gregory’s arrival in Washington follows months of intense speculation in the United States, with many bishops sharing the frustrations of local clerics and laity at the apparent delay in replacing Cardinal Wuerl after his resignation was accepted in October.

But the process of selecting the next archbishop of Washington was no less frustrating for those in Rome charged with making it happen.

Ordinarily, when a bishop resigns, the apostolic nuncio — in this case also resident in Washington — collects and submits a list of possible candidates, drawn from the recommendations of local clergy, nearby bishops and his own observations.

The outgoing bishop usually sends his own thoughts and recommendations to Rome, where the Congregation for Bishops examines the candidates before, in conjunction with the nuncio, presenting a final list of three names for the pope to consider.

That, at any rate, is how the process has traditionally operated. But the process for replacing Wuerl has been anything other than ‘business as usual.’

Cardinal Wuerl, 78, along with fellow U.S. Cardinal Blase Cupich of Chicago, is a member of the Congregation for Bishops. Both cardinals have played an active role in the process of considering a long list of names proposed for Washington, traveling to Rome for the Congregation’s regular sessions and weighing in with their own thoughts and suggestions over the past several months.

With Congress and the White House virtually in his backyard, Washington’s archbishop is often expected to play an outspoken role in public debate, while keeping the Church above the political fray.

One of Cardinal Wuerl’s great strengths as archbishop has been his ability to tread a narrow line: engaging with public affairs without appearing to take partisan political sides.

Finding a successor with the same skill set was a bedrock concern for Rome.

One of the most talked-about potential successors for Cardinal Wuerl was Cardinal Joseph Tobin of Newark, New Jersey. An outspoken advocate for migrant and refugee rights, both in New Jersey and previously in Indiana, Cardinal Tobin is known to be comfortable addressing hot-button issues.

Created a cardinal while still Archbishop of Indianapolis, Cardinal Tobin is also known to have the respect of Pope Francis who — according to multiple sources in the Curia, including at the Congregation for Bishops — was personally in favor of his appointment to Washington.

While many speculated that Cardinal Tobin would be a natural fit in an increasingly polarized Washington, sources say that objections were raised — including by several Congregation members — about how such a move would be perceived in the fallout of the scandals that rocked the Church in the United States last year.

The disgrace of Cardinal Wuerl’s immediate predecessor, Theodore McCarrick, has made the archdioceses he once led — Washington and Newark — the epicenters of the recent abuse crisis in America.

While the Archdiocese of Newark continues to grapple with its own legacy of scandal from the McCarrick era, some at the Congregation for Bishops expressed concern that moving Cardinal Tobin to Washington would be poorly received by local Catholics hoping for a bishop wholly unconnected to the McCarrick scandal.

According to multiple sources in Rome, one of the strongest voices in favor of a “clean break” replacement in Washington was Cardinal Wuerl himself.

In addition to cautioning against another Newark-Washington move, sources also told CNA that Cardinal Wuerl expressed deep reservations about other candidates who, though often touted as potential successors to Washington, had some connection to McCarrick or the scandal he created.

While various names were proposed, with Bishop Frank Caggiano of Bridgeport, Connecticut, known to have been suggested at one point, none were able to achieve both consensus at the Congregation and papal approval.

The eventual consensus that formed around Archbishop Gregory’s name appears to have been shaped by a number of factors.

As the president of the USCCB between 2001 and 2004, Archbishop Gregory is no stranger to dealing with the fallout of scandal, having played a leading role in the formation and implementation of the Dallas Charter and USCCB Essential Norms after the last sex abuse crisis.

Together with Cardinal Timothy Dolan of New York and Archbishop Joseph Kurtz of Louisville, Kentucky, Archbishop Gregory is part of a special task-force charged by the U.S. bishops with developing new proposals for enhanced episcopal accountability.

 A Chicago native, Archbishop Gregory arrived in Atlanta 14 years ago, having previously served as the bishop of Belleville and as an auxiliary in his home archdiocese.

Known to preserve close ties to his hometown, Archbishop Gregory was at one time considered a likely candidate to follow Cardinal Francis George in Chicago. According to several sources at the Congregation for Bishops, it was Cardinal George’s eventual successor, Cardinal Cupich, who proved instrumental in cementing Archbishop Gregory’s nomination.

Archbishop Gregory’s appointment, in addition to his distance from McCarrick’s former dioceses and his experience in responding to abuse scandals, also represents a long-awaited historic moment in the Church in the United States.

As the first African-American archbishop of an unquestionably top-tier diocese, he will be expected to be made a cardinal in the near future, possibly even before Cardinal Wuerl ages out of eligibility to vote in a papal conclave when he turns 80, more than a year from now.

Archbishop Gregory himself is 71, and arrives in Washington fewer than four years from the normal retirement age for bishops. While he faces a difficult final task in restoring confidence among the capital’s faithful, his age may have weighed in favor of his appointment, because he comes with a built-in option either to retire at 75 if he does not take to the role, or to continue in office past 75 if he does.

There will be some in Rome and Washington who will greet Archbishop Gregory warmly, while quietly viewing him as a stopgap appointment, a compromise after months of curial back-and-forth.

But Archbishop Gregory could confound such a view, by turning his age to his advantage.

The archbishop could, if he so chose, seize the opportunity to be more than a temporary steadying hand. As archbishop of Washington, likely a cardinal too, his will be one of the loudest voices in the Church in the U.S.

If he so chooses, the new archbishop could write himself into history as the face of transparency and reform in the Church’s hierarchy in the United States, especially given the freedom that will come from having to lead his diocese for only a few years’ time.

Alternatively, he could opt to see out his term quietly, restoring a sense of normalcy to a diocese hit hard by scandal.

The saying goes, “Beware the old man in a hurry.” It remains to be seen what kind of hurry Archbishop Gregory will be in, and how urgently and deeply he intends to leave his mark on Washington.
