The pope on Friday signed off on the miracle needed for the beatification of Pope John Paul II, and set May 1 as the date to honor one of the most beloved popes of all times as a model of saintliness for the church.
Pope Benedict XVI said in a decree that a French nun's recovery from Parkinson's disease was miraculous, the last step needed for beatification. A second miracle is needed for the Polish-born John Paul to be made a saint.
The May 1 beatification, which Benedict himself will celebrate, is expected to draw hundreds of thousands of pilgrims to Rome - a major morale boost for a church reeling from a wave of violence against Christians and fallout from the clerical sex abuse scandal.
Once he is beatified, John Paul will be given the title "blessed" and can be publicly venerated. Many people, especially in Poland, already venerate him privately, but the ceremony will make it official.
"This is a huge and important cause of joy," Warsaw Archbishop Kazimierz Nycz told reporters at his residence in the Polish capital.
Cardinal Stanislaw Dziwisz, John Paul's longtime secretary and friend, expressed "huge thanks" to Benedict for the decree. "We are happy today," he said.
Benedict put John Paul on the fast track to possible sainthood just weeks after he died in 2005, responding to the chants of "Santo Subito!" or "Sainthood immediately!" that erupted during his funeral.
Benedict waived the typical five-year waiting period before the process could begin, but he insisted that the investigation into John Paul's life be thorough so as to not leave any doubts about his virtues.
The last remaining hurdle concerned the approval by Vatican-appointed panels of doctors and theologians, cardinals and bishops that the cure of French nun, Sister Marie Simon-Pierre, was a miracle due to the intercession of John Paul.
The nun has said she felt reborn when she woke up two months after John Paul died, cured of the disease that had made walking, writing and driving a car nearly impossible. She and her fellow sisters of the Congregation of Little Sisters of Catholic Maternity Wards had prayed to John Paul, who also suffered from Parkinson's.
Last year, there were some questions about whether the nun's original diagnosis was correct. But in a statement Friday, the Congregation for the Causes of Saints said Vatican-appointed doctors had "scrupulously" studied the case and determined that her cure had no scientific explanation.
Born in Wadowice, Poland, in 1920, Karol Wojtyla was the youngest pope in 125 years and the first non-Italian in 455 years when he was elected pope in 1978.
He brought a new vitality to the Vatican, and quickly became the most accessible modern pope, sitting down for meals with factory workers, skiing and wading into crowds to embrace the faithful.
He was the most traveled pope ever, visiting more than 120 nations during the third-longest papacy and covering distance equal to nearly 1 1/2 trips to the moon.
