This might be the most pious stadium cheer of all-time.
A packed crowd at Daejeon World Cup Stadium showed its support for Pope Francis Friday by participating in the wave.
Video showed the visitors standing -- seat by seat, row by row, section by section, raising their arms. Many attendees clutched small flags.
Pope Francis held Mass at the stadium, part of the papal leader’s five-day trip in South Korea. He arrived Thursday, waving to onlookers from the back of a Kia Soul and delivering his first speech in English as pontiff.
