QUITO, Ecuador -- Pope Francis has a whirlwind final full day in Ecuador on Tuesday, with an open-air Mass in the capital sandwiched between meetings with bishops, indigenous groups and students and capped by a visit to a famed Jesuit church.
The 78-year-old pontiff, who has only one full lung, appears to be holding up well at the start of his eight-day, three-nation South American tour despite the 2,800-meter (nearly 9,200-feet) altitude of Quito and a day spent in the scorching sun of coastal Guayaquil. He had so much energy he slipped out again for a second night Monday to greet well-wishers who gathered outside the Vatican ambassador's residence where he is staying.
"It's always surprising what the pope can do at his age," said the Vatican spokesman, the Rev. Federico Lombardi. He noted that several people in the Vatican entourage awoke Monday with headaches due to altitude sickness, but not the pope.
"He has said it's God's way of helping him do his ministry, his service," Lombardi said.
Francis received a hero's welcome Monday in Guayaquil, Ecuador's biggest city, as he celebrated the first public Mass of a South American tour that will later take him to Bolivia and Paraguay. He told hundreds of thousands of faithful their families are the bedrock of society but need to be supported better and strengthened.
Crowd estimates varied, with the government spokesman putting it at around 550,000 while Lombardi said it was "plausible and honest" to say 1 million people were on hand.
In his homily, Francis praised families as the nucleus of society, calling them "the nearest hospital, the first school for the young, the best home for the elderly." He said miracles are performed every day inside a family out of love, but sometimes the love and happiness run out.
"How many women, sad and lonely, wonder when love left, when it slipped away from their lives?" he asked. "How many elderly people feel left out of family celebrations, cast aside and longing each day for a little love?"
