Pope Francis received a rousing welcome for his first Angelus, the weekly address delivered from the papal apartment at St. Peter's square.
Speaking in Italian, Pope Francis greeted worshipers.
An estimated 150,000 people filled the square and surrounding streets, some of the faithful jumped barricades for a good view.
Earlier Pope Francis greeted priests and waved to parishioners before conducting mass at St. Anna, a tiny church for workers in Vatican City.
His sermon delivered without notes urged listeners not to condemn others, but to follow Jesus' teachings of forgiveness.
For Catholics happy to have a new pope, the new style seems to be working.
