Pope Francis gave his first Sunday blessing this morning to the more than 100,000 people gathered in St. Peter’s Square in Vatican City.
Dozens of flags from Francis’s native Argentina were waving in the crowd.
The new pontiff delivered the Angelus prayer from the window of his papal apartment.
Pope Francis will formally be installed as the new leader of the world’s Roman Catholics Tuesday.
A U.S. delegation, led by Vice President Joe Biden, will attend the Tuesday ceremony.
