VATICAN CITY (AP) - On the streets in Buenos Aires, the stories about the cardinal who would become the first pope from the Americas often include a very ordinary backdrop: The city bus during rush hour. Tales are traded about chatting with Archbishop Jorge Bergoglio as he squeezed in with others for the commute to work. They sometimes talk about church affairs. Other times it could be about what he planned to cook for dinner in the simple downtown apartment he chose over an opulent church estate. Or perhaps it was a mention of his affection for the tango, which he said he loved as a youth despite having one lung removed following an infection. On the balcony of St. Peter's Basilica just after a rain shower Wednesday, wearing unadorned white robes, the new Pope Francis also appeared to strike the same tone of simplicity and pastoral humility for a church desperate to move past the tarnished era of abuse scandals and internal Vatican upheavals. While the new pontiff is not without some political baggage, including questions over his role during a military dictatorship in Argentina in the 1970s, the selection of the 76-year-old Bergoglio reflected a series of history-making decisions by fellow cardinals who seemed determined to offer a suggestion of renewal to a church under pressures on many fronts. "He is a real voice for the voiceless and vulnerable," said Kim Daniels, director of Catholic Voices USA, a pro-church group. That is the message. Pope Francis, the first from Latin America and the first from the Jesuit order, bowed to the crowds in St. Peter's Square and asked for their blessing in a hint of the humble style he cultivated while trying to modernize Argentina's conservative Roman Catholic Church and move past a messy legacy of alleged complicity during the rule of the military junta of 1976-83. "Brothers and sisters, good evening," he said before making a reference to his roots in Latin America, which accounts for about 40 percent of the world's Roman Catholics. Groups of supporters waved the white-and-blue Argentine flags in St. Peter's Square as Francis made his first public appearance as pope. Bergoglio reportedly had envoys urge Argentines not to fly to Rome to celebrate his papacy, but instead donate money to the poor. In taking the name Francis, he drew connections to the 13th century St. Francis of Assisi, who saw his calling as trying to rebuild the simple spirit of the church and devote his life to missionary journeys. It also evokes references to Francis Xavier, one of the 16th century founders of the Jesuit order that is known for its scholarship and outreach. Francis, the son of middle-class Italian immigrants, came close to becoming pope during the last conclave in 2005. He reportedly gained the second-highest vote total in several rounds of voting before he bowed out of the running before selection of Vatican insider Joseph Ratzinger, who became Pope Benedict XVI. By returning to Bergoglio, the conclave confounded speculation that it would turn to a younger candidate more attuned to younger elements in the church and with possibly more stamina for the rigors of the modern papacy with nearly nonstop obligations and frequent global travel. Francis appears in good health, but his age and possible limitations from his single lung raise questions about whether he can face the demands of the position. Unlike many of the other papal contenders, Bergoglio never held a top post inside the Vatican administration, or curia. This outsider status could pose obstacles in attempts to reform the Vatican, which has been hit with embarrassing disclosures from leaked documents alleging financial cover-ups and internal feuds. But the conclave appeared more swayed by Bergoglio's reputation for compassion on issues such as poverty and the effects of globalization, and his fealty to traditional church teachings such as opposition to birth control. His overriding image, though, is built around his leaning toward austerity. The motto chosen for his archdiocese is "Miserando Atque Eligendo," or "Lowly but Chosen." Even after he became Argentina's top church official in 2001, he never lived in the ornate church mansion where Pope John Paul II stayed when visiting the country, preferring a simple bed in a downtown building, warmed by a small stove on frigid weekends when the building turned off the heat. Bergoglio almost never granted media interviews, limiting himself to speeches from the pulpit, and was reluctant to contradict his critics, even when he knew their allegations against him were false, said Bergoglio's authorized biographer, Sergio Rubin. Bergoglio's legacy as cardinal includes his efforts to repair the reputation of a church that lost many followers by failing to openly challenge Argentina's dictatorship. He also worked to recover the church's traditional political influence in society, but his outspoken criticism of President Cristina Fernandez couldn't stop her from imposing socially liberal measures that are anathema to the church, from gay marriage and adoption to free contraceptives for all. His church also had no say when the Argentine Supreme Court expanded access to legal abortions in rape cases, and when Bergoglio argued that gay adoptions discriminate against children. Fernandez compared his tone to "medieval times and the Inquisition." Yet Bergoglio has been tough on hard-line conservative views among his own clerics, including those who refused to baptize the children of unmarried women. "These are today's hypocrites; those who clericalize the church," he told his priests. This sense of humility is very well seen in Rome," said the biographer Rubin. His preference to remain in the wings, however, has been challenged by rights activists seeking answers about church actions during the dictatorship after the 1976 coup, often known as Argentina's "Dirty War." It's one reason why more than two-thirds of Argentines describe themselves as Catholic, but less than 10 percent regularly attend Mass. Bergoglio has been very critical of human rights violations during the dictatorship, but he has always also criticized the leftist guerrillas. He doesn't forget that side," said the biographer Rubin. The statements came far too late for some activists, who accused Bergoglio of being more concerned about the church's image than about aiding the many human rights investigations into the junta era. Bergoglio twice invoked his right under Argentine law to refuse to appear in open court. When he eventually did testify in 2010, his answers were evasive, human rights attorney Myriam Bregman said. At least two cases directly involved Bergoglio, who ran Argentina's Jesuit order during the dictatorship. One examined the torture of two of his Jesuit priests - Orlando Yorio and Francisco Jalics - who were kidnapped in 1976 from the slums where they advocated liberation theology, which is the belief that Jesus Christ's teachings justify fights against social injustices. Both men were freed after Bergoglio took extraordinary, behind-the-scenes action to save them, including persuading dictator Jorge Videla's family priest to call in sick so that Bergoglio could say Mass in the junta leader's home, where he privately appealed for mercy. Bergoglio told Rubin that he regularly hid people on church property during the dictatorship, and once gave his identity papers to a man with similar features, enabling him to escape across the border. But rights attorney Bregman said Bergoglio's own statements proved church officials knew from early on that the junta was torturing and killing its citizens, and yet publicly endorsed the dictators. Bergoglio also was accused of turning his back on a family that lost five relatives to state terror, including a young woman who was five months' pregnant before she was kidnapped and killed in 1977. Months passed before the monsignor came back with a written note from a colonel: The woman had given birth in captivity to a girl who was given to a family "too important" for the adoption to be reversed. He says he didn't know anything about it until 1985," said the baby's aunt, Estela de la Cuadra, whose mother, Alicia, co-founded the Grandmothers of the Plaza de Mayo in 1977 in hopes of identifying these babies. "He doesn't face this reality and it doesn't bother him," the aunt said. Later, there was little love lost between Bergoglio and Argentina's government. Relations became so frigid that the president stopped attending his annual "Te Deum" address, when church leaders traditionally tell political leaders what's wrong with society. Is Bergoglio a progressive, a liberation theologist even? He's no Third World priest," said Rubin.
