Pope Benedict XVI acknowledges audience during Mass at Yankee Stadium in New York, 20 Apr 2008

Pope Benedict XVI returned to Rome Monday, after his six-day trip to the United States.

The pope's U.S. visit included a meeting with President Bush, outdoor Masses, and a visit to one of the sites attacked on September 11, 2001.

During his trip, the pope repeatedly referred to the sexual abuse scandal that has wracked the U.S. church. He had an unprecedented meeting with victims of abusive priests.

Benedict celebrated Mass Sunday at a New York City baseball stadium packed with 57,000 worshippers.

The pope was met with loud cheers when he arrived at Yankee Stadium. Some in the crowd waved handkerchiefs in the Vatican's colors - white and yellow.
