Pope Francis greeted hundreds of people in wheelchairs one-by-one — part of a gathering Saturday in which rows of seats were removed from an auditorium at the Vatican to make room for the disabled visitors. The pontiff, who has made championing the downtrodden a priority, lamented that society tends to "hide physical fragility" and reject the disabled. He encouraged those with physical disabilities to banish feelings of shame and become "protagonists" in society as well as the Catholic church. Some 600 people in wheelchairs waited to have their time with Francis. He moved down the rows to dole out hugs and kisses and chat with people.
