Here are the latest developments from Pope Francis' trip to South America:
At the last stop of his South American trip, three young people have given Pope Francis very personal testimonies about their lives, which haven't been easy.
The pope was particularly moved by the story told by 25-year-old Liz Fretes. She says her mother lost her cognitive faculties and "became like a child." Their roles were reversed: Fretes became the caregiver, having to change her mother's diapers, bathe her and play with her as if with a child.
Fretes thought she would never be able to make something of herself. But someone paid for her studies and she is now a nurse. She cared for her mother and her grandmother by day and went to school at night.
Fretes said she understands that her mother's illness has made her stronger.
After she spoke, the pope blessed her, kissed her forehead and hugged her. The two exchanged words privately. Then Fretes reached up and around the pope and hugged him again.
Pope Francis is arriving to the final event of his three-country tour in South America.
He plans to address tens of thousands of young people waiting for him at a venue along the banks of the Paraguay River in Asuncion.
Paraguayan national flags and other banners are being waved and the crowd is particularly loud.
After the meeting, the pope is scheduled to say a prayer at the site of a supermarket fire that killed hundreds in 2004. Then he plans to fly back to Rome.
The head of the Greek Orthodox Church in South America has had a privileged spot at Pope Francis' events this week.
Metropolitan Tarasios is an old friend of the pope's from Buenos Aires, where he is based.
The Vatican spokesman, the Rev. Federico Lombardi, said Sunday that Tarasios asked Francis if he might participate in the trip, and he traveled from Ecuador to Bolivia and to Paraguay on his own. On Sunday, he gave a greeting at Francis final Mass in Asuncion.
Lombardi said his presence "gave an ecumenical dimension to the trip, which otherwise wasn't very evident."
Indeed, Francis' pilgrimage has been notable for the absence of any meetings between the pope and leaders of other faiths — usually a mainstay of papal trips.
Francis has very friendly relations with the Orthodox Church; he recently cited the works of Ecumenical Patriarch Bartholomew I in his encyclical on the environment.
Pope Francis is starting to show the effects of his gruelling three-nation, week-long trip half-way across the world from Rome.
The 78-year-old Francis appeared to doze off a bit at the end of Mass on Sunday when the archbishop of Asuncion, Paraguay delivered a lengthy speech of thanks for his visit.
The Vatican spokesman, the Rev. Federico Lombardi, said it's only natural that Francis "isn't in the condition in which he left Rome" given his packed schedule.
Francis added to his official itinerary some impromptu visits on Saturday to a hospital and a Jesuit church and meetings with friends and family who came to Paraguay from Argentina.
But Lombardi says Francis tends to rally, especially when he's surrounded by the kind of young people who will be the focus of his final event Sunday.
