It was only a year ago that Cardinal Timothy M. Dolan, the archbishop of New York, received his red hat in Rome, marking him as one of the princes of the Roman Catholic Church.

But suddenly, he found himself in even more rarefied company, with his name mentioned alongside those of more long-serving cardinals as a potential next pope, even though, by all accounts, his chances are slim.

The news on Monday of Pope Benedict XVI’s resignation came as a surprise to Cardinal Dolan, as it did to most of the world. But within hours, his life was already changed. As he continued to go about his regular business as archbishop, he found himself even more in the spotlight to which he has become accustomed, facing a glare that will quite likely continue at least through the conclave in Rome next month.

On Monday, when he dedicated a chapel in Rockland County and attended a prayer meeting in the Bronx, he also ricocheted between media appearances, beginning at 7 a.m. on “Today,” the NBC program, then holding a news conference, writing an op-ed essay, and granting interviews to ABC and CBS. He was still talking to reporters as night fell, holding an impromptu news conference outside the New York Athletic Club on Central Park South before going inside for a fund-raiser. Both Mayor Michael R. Bloomberg and Gov. Andrew M. Cuomo fielded questions from reporters about the possibility that Cardinal Dolan could become pope; on late-night television, Stephen Colbert offered his endorsement (what he called a “Colbert bump”) for Cardinal Dolan for pope.
