Argentine Jorge Bergoglio has been elected pope, the first ever from the Americas and the first from outside Europe in more than a millennium. He chose the name Pope Francis.After announcing "Habemus Papum” — "We have a pope!” — a cardinal standing on the balcony of St. Peter’s Basilica yesterday revealed the identity of the new pontiff, using his Latin name. Bergoglio had reportedly finished second in the 2005 conclave that produced Benedict XVI — who last month became the first pope to resign in 600 years. The 76-year-old archbishop of Buenos Aires has spent nearly his entire career at home in Argentina, overseeing churches and shoe-leather priests.Chants of "Long live the pope!” arose from the throngs of faithful, many with tears in their eyes. Crowds went wild as the Vatican and Italian military bands marched through the square and up the steps of the basilica, followed by Swiss Guards in silver helmets and full regalia.In Rwanda, Bishop Smaragde Mbonyintege, the Bishop of Kabgayi Diocese said the Catholic Church in Rwanda was surprised by Cardinal Bergoglio’s election as pope. "But we trust the cardinals that voted for him because they know him better than we do,” Bishop Mbonyintege, who is also the spokesperson of the Catholic Church in Rwanda said. He said the name chosen by the new pope reflects humility and love to the poor according to the gospel.  About the chances of having an African pope, Bishop Mbonyintege said the most important thing is to have a universal pope and hopes that Pope Francis maintains church unity.Elected on the fifth ballot, the pope was chosen in one of the fastest conclaves in years, remarkable given there was no clear front-runner going into the vote and that the church had been in turmoil following the upheaval unleashed by Pope Benedict XVI’s surprise resignation.A winner must receive 77 votes, or two-thirds of the 115, to be named pope.Other contenders For comparison’s sake, Benedict was elected on the fourth ballot in 2005 — but he was the clear front-runner going into the vote. Pope John Paul II was elected on the eighth ballot in 1978 to become the first non-Italian pope in 455 years.The conclave played out against the backdrop of the first papal resignation in 600 years and revelations of mismanagement, petty bickering, infighting and corruption in the Holy See bureaucracy. Those revelations, exposed by the leaks of papal documents last year, had divided the College of Cardinals into camps seeking a radical reform of the Holy See’s governance and those defending the status quo.The names mentioned most often as "papabile” — a cardinal who has the stuff of a pope — included Cardinal Angelo Scola, the archbishop of Milan, an intellect in the vein of Benedict but with a more outgoing personality, and Cardinal Marc Ouellet, the Canadian head of the Vatican’s important bishops’ office who is also scholarly but reserved like Benedict.Brazilian Cardinal Odilo Scherer is liked by the Vatican bureaucracy but not by all of his countrymen. And Cardinal Peter Erdo of Hungary has the backing of European cardinals who have twice elected him as head of the European bishops’ conference.On the more pastoral side is Cardinal Sean O’Malley of Boston, the favorite of the Italian press, and Cardinal Timothy Dolan, the back-slapping, outgoing archbishop of New York who has admitted himself that his Italian is pretty bad — a drawback for a job that is conducted almost exclusively in the language.The Vatican spokesman, the Rev. Federico Lombardi said it was a "good hypothesis” that the pope would be installed next Tuesday, on the feast of St. Joseph, patron saint of the universal church. The installation Mass is attended by heads of state from around the world, requiring at least a few days’ notice.Benedict would not attend, he said.Thousands of people braved a chilly rain on Wednesday morning to watch the 6-foot- (2-meter-) high copper chimney on the chapel roof for the smoke signals telling them whether the cardinals had settled on a choice. Nuns recited the rosary, while children splashed in puddles.Unlike the confusion that reigned during the 2005 conclave, the smoke this time around was clear: black during the first two sets of smoke signals, and then clearly white yesterday night — thanks to special smoke flares akin to those used in soccer matches or protests that were lit in the chapel ovens to accompany the smoke from the burned ballot papers.The Vatican divulged the secret recipe used: potassium perchlorate, anthracene, which is a derivative of coal tar, and sulfur for the black smoke; potassium chlorate, lactose and a pine resin for the white smoke.The chemicals were contained in five units of a cartridge that is placed inside the stove of the Sistine Chapel. When activated, the five blocks ignite one after another for about a minute apiece, creating the steady stream of smoke that accompanies the natural smoke from the burned ballot papers.Despite the great plumes of smoke that poured out of the chimney, neither the Sistine frescoes nor the cardinals inside the chapel suffered any smoke damage, Lombardi said.
