Pope Francis, over the weekend, wrapped up his historic Latin America tour with a visit to a slum and a Mass attended by about a million faithful, CBS News reported.

On the final day of his visit, the Argentinian-born pontiff stopped by the Bañado Norte shantytown on the outskirts of Asunción, Paraguay's capital, which is home to approximately 15,000 families. The head of the world's estimated 1.2 billion Catholics mingled, shook hands and hugged residents.

"I could not come to Paraguay without spending time with you here on your land," Francis noted as he took sides in a conflict that has pegged real-estate developers against Bañado Norte's poor. "I want to be your neighbor."

The pope then celebrated Mass with close to a million people, many from his homeland just across the border. At the ceremony, he also had a brief encounter with Argentine President Cristina Fernández de Kirchner, who had flown in from Buenos Aires to greet Francis, Clarín noted.

In his homily, meanwhile, he challenged the faithful to live life "according to a different standard."

That means "to cross from the logic of egotism, from the fight of betrayal, to the logic of love; from the logic of domination, of crushing, to the logic of welcoming, of receiving and caring," the pope explained. "(These are) two ways of going about one's life."

Before boarding his flight back to Rome, Francis used a farewell ceremony to urge Latin America's young people to shake up society, The Associated Press reported.

"The mess that young people make, we then have to clean it up ourselves," he noted. "Shake things up, but then clean it up and fix the mess that you've made."

Francis's visit, which had begun on July 5, took the pope to Ecuador, Bolivia and Paraguay. Later this year -- and after a stopover in Cuba -- the head of the Roman Catholic Church is scheduled to come to the United States, where he is set to visit the White House and address a joint session of Congress.
