Thousands chant “Habemus papam!” in St. Peter’s Square. “We have a pope!” After a day and a half of voting, the 115 cardinal electors have made a decision and the white smoke blows out of the chimney roof. At least 77 of the voters agreed on who would succeed Pope Bendict XVI. So, who will reign over the estimated 1.2 billion Catholics? Archbishop of Buenos Aires, Cardinal Jorge Mario Bergoglio of Argentina. He is 77 years-old.
