Daejeon: Pope Francis warned of the "cancer" of despair that afflicts outwardly affluent societies and called on South Korean Catholics to reject "inhuman economic models" at a mass for 45,000 people on Friday on the first papal trip to Asia in 15 years.
In an apparent reference to South Korea`s high suicide rate, he also warned of the "culture of death" that can pervade rapidly developing countries where the poor are marginalised.
It was the pope`s first public event following his arrival in Seoul on Thursday, which nuclear-armed North Korea marked by firing a series of short-range rockets into the sea.
A capacity crowd had crammed the World Cup stadium in Daejeon, some 160 kilometres (100 miles) south of Seoul, hours before the pope arrived to conduct the mass.
Among them were 38 survivors and relatives of victims of April`s Sewol ferry tragedy in which 300 people died, most of them schoolchildren.
During the mass, Pope Francis offered a special prayer for the victims and their families, and urged Koreans "united in grief" to work together for the common good.
Before the mass, he held a brief private audience with some of the relatives, and agreed to baptise the father of one of the student victims at the Vatican embassy in Seoul on Saturday.
The ferry tragedy has largely been blamed on a culture of regulatory negligence, fuelled by the drive to place profit over safety.In his homily, Francis called on South Korean Christians to combat "the spirit of unbridled competition which generates selfishness and strife" and to "reject inhuman economic models which create new forms of poverty."
He also spoke of the "cancer" of despair that can permeate societies where surface affluence hides deep inner sadness.
"Upon how many of our young has this despair taken its toll," he said.
It was a message designed to resonate not just with South Koreans, but other emerging Asian nations where decades of rapid economic growth have thrown up stark social challenges.
Trees lining the streets leading to the stadium were tied with the yellow ribbons that have become the memorial symbol for those who died on the Sewol ferry.
"I`m a Protestant but I believe the papal visit will help heal the wounds from the Sewol disaster," one of the victims` relatives, Kim Hyeong-Ki, told AFP.
Thousands without tickets for the mass had cheered and waved flags as the pope rode to the venue in an open-topped car, stopping from time to time to give a personal blessing to young children and infants held up by their parents."I think this is the most important and unforgettable moment of my life," said Han Hye-Jin, 26, an office worker in Daejeon.
As the pope entered the stadium, the capacity crowd rose, waving white handkerchiefs and shouting "Viva Papa" and "Mansei" ("Long live" in Korean).
The mass was conducted on a raised, canopied stage with giant screens on either side for those high up in the stands, which were decorated with banners in Korean reading "We Will Always Follow you" and "We Love You".
South Korea has a thriving Catholic community that punches well above its minority weight in one of Christianity`s most muscular Asian strongholds.
In the last national census to include religious affiliation, conducted in 2005, close to 30 percent of South Koreans identified themselves as Christian, compared to 23 percent who cited the once-dominant Buddhism.
The majority are Protestants, but Catholics are the fastest-growing group, with around 5.3 million adherents -- just over 10 percent of the population.
"I only hope the pope`s message of peace and reconciliation will spread to our brothers and Catholic followers in North Korea," said Helena Sam, 46, a businesswoman in Daejeon.
The North pays lip-service to the freedom of worship but maintains the tightest controls over religious activity and treats unsanctioned acts of devotion as criminal.
The pope`s visit is very much aimed at fuelling a new era of growth for the Catholic church in Asia and Francis will get a chance to send a message to the region later Friday when he meets several thousand young Catholics gathered in Daejeon for Asian Youth Day.
