In his catechesis, the pope continued his series of talks on prayer in the letters of St. Paul, looking this time at the Letter to the Philippians.

People often look for "self-actualization in power, domination and in powerful means," creating a tower of Babel in a quest to be god-like, said the pope. Such pursuits reflect the sin of Adam, who sought to put himself ahead of God.

Jesus, instead, showed that true exaltation and victory come with absolute abasement and humility -- being a servant to others and obeying God's will, even to the point of being killed on the cross, the pope said.

By becoming fully human and obeying God, he said, Jesus gave humanity back the dignity it had lost with Adam's disobedience.

"As Jesus exaltation took place through his abasement, so in our lives and in our prayer we discover that, by lowering ourselves in humility and love, we are lifted up to God."

"The incarnation and the cross remind us that complete fulfillment comes in conforming the human will to the Father's, in emptying oneself of egoism and in filling oneself with God's love and charity, thereby becoming truly capable of loving others," he said.

Noting the upcoming feast of Sts. Peter and Paul, June 29, the pope asked pilgrims in Rome to visit the saints' tombs as a way of "deepening your love for Christ's church, founded on the apostles."

At the end of the audience, attended by an estimated 7,000 pilgrims and visitors, the pope reminded his listeners to use their summer holidays for helping others and themselves.

He told young people to do something that would lead to "useful social and religious experiences," and encouraged newlyweds to grow in their love and "deepen your mission in the church and society."
