Pope Francis has bid the United States farewell. His plane departed for Rome on Sunday night, thus bringing to a close his first visit to U.S. soil.
"My days with you have been brief, but they have been days of great grace for me. And I pray for you, too," the pontiff said, in a brief ceremony at the Philadelphia International Airport before his flight's departure. "As I prepare to leave, I do so with a heart full of gratitude and hope."
