FILE - In this March 18, 2013 file photo provided by the Vatican paper L'Osservatore Romano, Pope Francis is presented a mate gourd and straw, to hold the traditional Argentine tea, by Argentine President Cristina Fernandez, during their meeting at the Vatican. Catholic doctrine considers the pope to be God's delegate on Earth. That alone might explain the remarkable about-face that Argentina's president and most of her followers have managed to pull off in the days since the cardinal she treated as a political arch-enemy became Pope Francis.
