Some 1.5 million pilgrims flooded Rome Sunday to watch Pope John Paul II move a step closer to sainthood in one of the largest Vatican Masses in history, an outpouring of adoration for a beloved and historic figure after years marred by church scandal.

The turnout for the beatification far exceeded even the most optimistic expectation of 1 million people, the number Rome city officials predicted. For Catholics filling St. Peter's Square and its surrounding streets, and for those watching around the world the beatification was a welcome hearkening back to the days when the pope was almost universally beloved.

"He was like a king to us, like a father," Marynka Ulaszewska, a 28-year-old from Ciechocinek, Poland, said, weeping. "I hope these emotions will remain with us for a long time," she said.

Benedict was responding to chants of "Santo Subito!" or "Sainthood Immediately" which erupted during John Paul's funeral. Beatification is the last major milestone before a candidate is declared a saint. John Paul needs another miracle attributed to his intercession before he can be canonized.

Already, Vatican officials have said reports of inexplicable cures were pouring in, suggesting it is only a matter of time before John Paul is declared a saint, or even a doctor of the church — an even greater honor.

After the nearly three-hour Mass, Benedict prayed before John Paul's coffin, which had a copy of the Lorsch Gospels on it, an illuminated medieval book of the Gospels that is one of the most precious in the Vatican's collection.

During the Mass, Benedict received a silver reliquary holding a vial of blood taken from John Paul during his final hospitalization. The relic, a key feature of beatification ceremonies, will be available for the faithful to venerate.
