Pope Francis, who was visiting Mozambique Sept. 4, expressed his sorrow after hearing the news of the cardinal's death.

He praised “the efforts made in recent decades to ensure that peace is once more the norm and reconciliation the best path to confront the difficulties and challenges that you face as a nation.”

When Pope Francis arrives in Mozambique on Sept. 4 he is going to a country that he already knows much about from his time as archbishop of Buenos Aires, the Rev. Juan Gabriel Arias, 50, told America on the eve of the papal visit.

"Thank God the firefighters intervened," Francis said, referring to tiny Vatican City State's own fire department.

Pope Francis said that the forthcoming United Nations Climate Action Summit “is of particular importance.”

10 of the 13 new cardinals will be eligible to vote in the next conclave, including Jesuit Father Michael Czerny, who oversees the Vatican department for migrants and refugees.
