A recent interview with Archbishop Konrad Krajewski, the "Almoner of His Holiness," raised speculation that the Pope joins him on his nightly trips into Rome to give alms to the poor, and it turns out that the rumors are probably true.
A knowledgable source in Rome said that "Swiss guards confirmed that the pope has ventured out at night, dressed as a regular priest, to meet with homeless men and women."
He's not the only Pope known for nocturnal wanderings. There are stories of Pope John XIII sneaking out to enjoy the beauty of Rome in the evenings, and reports tell of Pope Pius XII dressing as a Franciscan during WWII to help smuggle Rome's Jewish population to safety.
More recently, Pope Benedict XVI popped out unannounced to visit an art exhibit.
When Pope Francis was Cardinal Jorge Bergoglio, he was known to sneak out at night to break bread with the homeless, sitting with them on the street and eating with them to show that they were loved. And we love him for doing it now!
