Pope Francis on Sunday led his first major service since his election, calling on the crowd to shun corruption and reach out to "the humble, the poor, the forgotten."
"Let us look around: How many wounds are inflicted upon humanity by evil! Wars, violence, economic conflicts that hit the weakest, greed for money, power, corruption, divisions, crimes against human life and against creation," he said.
The new pope invoked the wisdom of his grandmother and used simple language at the Palm Sunday service, which marks the start of the Holy Week of Easter in celebration of the crucifixion and resurrection of Jesus Christ.
Pope Francis departed from his prepared text, and when he referred to wealth, said: "You can't take it with you, my grandmother used to say."
