"In this photo provided by the Vatican paper L'Osservatore Romano, Pope Francis meets Pope emeritus Benedict XVI in Castel Gandolfo Saturday, March 23, 2013. Pope Francis has traveled to Castel Gandolfo to have lunch with his predecessor Benedict XVI in a historic and potentially problematic melding of the papacies that has never before confronted the Catholic Church. The Vatican said the two popes embraced on the helipad. In the chapel where they prayed together, Benedict offered Francis the traditional kneeler used by the pope. Francis refused to take it alone, saying ""We're brothers,"" and the two prayed together on the same one. (AP Photo/Osservatore Romano, HO)"
