"How many times," the pope asked, "are we impatient, nervous, always ready to complain" and to criticize others as if "we were the bosses of the world when in reality we are all children of God?"

Jesus showed his followers that meekness is the path to eternal happiness, the pope said. Although the son of God, he experienced exile as a child in Egypt, he was slandered, falsely accused and condemned. But "he took it all with meekness. He bore it out of love for us, even to the cross."

Those who hunger and thirst for justice, the pope said, "will be satisfied because they are ready to welcome the greater justice, which is what only God can give."

The merciful are blessed because they have experienced the truth that everyone is in need of forgiveness and mercy, the pope said. "They don't judge everything and everyone, but try to put themselves in the other's shoes."

Mass always begins with asking God's forgiveness and mercy; it is a time when "we recognize ourselves for what we are, sinners. It's not just a saying, a formality," he said. "And if we learn how to give others the forgiveness that we ask for ourselves, we will be blessed."

The Beatitudes say that peacemakers will be blessed and that is something often visible in the here and now, he said. "Look at the faces of those who go around sowing discord; are they happy? Those who always look for opportunities to trick others, to take advantage of others, are they happy? No, they cannot be happy."

But those who patiently try each day to promote peace and reconciliation, even through small gestures at home and at work, "are blessed because they are true children of our heavenly Father, who always and only sows peace."

As dusk approached, Pope Francis asked the thousands of people gathered in the cemetery to pray with him for "the grace to be simple and humble people, the grace to know to weep, the grace to be meek, the grace to work for justice and peace and, especially, the grace to let ourselves be forgiven by God in order to become instruments of his mercy."

Earlier in the day, the pope recited the Angelus with visitors gathered in St. Peter's Square, focusing on the call to be saints that all Christians receive at baptism.

The saints officially recognized by the church and the saints "next door" are models to imitate and are those who give people encouragement, he said.

At baptism, the pope said, "we received the 'seal' of our heavenly Father and we became his children. To put it simply, we have God's last name," and a vocation to holiness.

The saints -- formally recognized by the church or known only to their families and friends -- are those who have kept that seal intact and behaved as children of God, he said.

"To imitate their gestures of love and mercy is a bit like continuing their presence in the world," he said. "These evangelical gestures are the only ones that resist the destruction of death. An act of tenderness, generous help, time spent listening, a visit, a nice word, a smile -- these can seem insignificant, but in the eyes of God they are eternal because love and compassion are stronger than death."
