Pope Benedict XVI told diplomats at the United Nations on Friday that respect for human rights was the key to solving many of the world's problems.
The pontiff said the organization's work is vital, but he raised concerns that power is concentrated among just handful of players.
"Multilateral consensus," he said, speaking in French, "continues to be in crisis because it is still subordinated to the decisions of a small number."
The world's problems call for collective interventions by the international community, he said.
"The promotion of human rights remains the most effective strategy for eliminating inequalities between countries and social groups, and increasing security," the pope said.
Before the pontiff's speech, Benedict and Secretary-General Ban Ki-moon met alone for 15 minutes.
Third Pope to Address the U.N.
Benedict, only the third pope to address the United Nations, made the remarks after he repeatedly discussed America's clergy sexual abuse scandal.
It remains to be seen whether Benedict will continue to talk about the sexual abuse crisis.
He has been widely expected to broach the subject on Saturday when he celebrates Mass for priests, deacons and members of religious orders at St. Patrick's Cathedral in Manhattan.
On Thursday, Benedict met privately with abuse victims between an open-air Mass at Nationals Park and a meeting with Catholic educators.
The Rev. Federico Lombardi, a papal spokesman, said that Benedict and Boston Cardinal Sean O'Malley met with a group of five or six abuse victims for about 25 minutes, offering them encouragement and hope. The group from O'Malley's archdiocese were all adults, men and women, who had been molested when they were minors. Each spoke privately with the pope and the whole group prayed together.
One of the victims, Bernie McDaid, told The Associated Press that he shook the pope's hand, told him he was an altar boy and had been abused by a priest in the sacristy of his parish. The abuse, he told Benedict, was not only sexual but spiritual.
'Cancer' in the Flock
"I said, 'Holy Father, you need to know you have a cancer in your flock and I hope you will do something for this problem; you have to fix this,"' McDaid said. "He looked down at the floor and back at me, like, 'I know what you mean.' He took it in emotionally. We looked eye to eye."
Benedict's address to the presidents of Catholic colleges and universities was among the most anticipated of his trip, but was overshadowed by the meeting with victims.
The pope, a former academic, said academic freedom has "great value" for the schools, but does not justify promoting positions that violate the Catholic faith.
The pope's New York visit will also include a visit to ground zero and a Mass at Yankee Stadium on Sunday. Later Friday, he was to visit a synagogue and meet with leaders of other Christian denominations.
