Open Image ModalNaples' Archbishop Cardinal Crescenzio Sepe looks at the relic believed to be the blood of San Gennaro, the patron of Naples, just after Pope Francis held and kissed it, repeating the phenomenon of liquefaction of the blood, during a meeting with prelates in Naples' Cathedral, Saturday, March 21, 2015. The blood partially liquefied and Francis said that that was the the saint's way to say: "we need to convert ourselves more" because the blood only partially dissolved. Neapolitans recalled that the blood didn't dissolve during visits by the previous two popes, Benedict XVI and John Paul II. Francis is on a one-day visit to Naples and Pompeii.
