It was an historical luncheon between retired Pope Benedict XVI and the newly elected Pope Francis I. 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. Benedict has been living at the papal summer villa since he resigned Feb. 28, the first pope to step down in 600 years. He has said he plans to live out his final years in prayer and remain "hidden from the world."
