Pope Francis recounted: "one day she was killed in a robbery; everyone wept, Christians and Muslims. They really loved her!"
"She announced the Gospel with her life, with the works she accomplished, a center of instruction; in this way she spread the flame of faith, she fought the good fight," he continued. "Let us think about this our sister, and greet her with applause, all of us!"
The pontiff also spoke of the life of Stefano Sandor, a lay Salesian who was beatified Saturday in Budapest.
Pope Francis said Sandor was "exemplary in service to young people, in the oratory and in professional instruction." The Hungarian confronted the Communist persecution of Catholics "with courage" and was killed at the age of 39.
Pope Francis also took a moment to remember the people of the Philippines who suffered from a 7.1-magnitude earthquake on Oct. 15. The earthquake killed over 150 people and affected nearly 3.5 million others.
"I invite you to pray for that dear nation, which in recent days has suffered different calamities," he requested.
The Pope concluded by greeting the various groups present, including those who had gathered for a 100-meter "race for faith" held by the Pontifical Council for Culture.
He had special words for visitors from his homeland Argentina, which celebrates Mother's Day today.
"I offer an affectionate greeting to the mothers of my land!" he said with a smile.
