For the first time in his 26-year pontificate, John Paul was missing the Way of the Cross procession Friday night, which re-enacts Christ's crucifixion amid the haunting ruins of Rome's torch-lit Colosseum.
Vatican TV installed equipment at the Colosseum in case the pope was able to appear via video linkup from the Vatican, but the final decision was to be made at the last minute depending on his health.
Catholic pilgrims were not discouraged by the absence of the pope. reports CBS News' Sabina Castelfranco. They turned out in the thousands to take part in the Passion of the Lord service in St. Peter's Basilica, with American Cardinal Francis Stafford presiding over the solemn service.
The preacher for the papal household, the Rev. Raniero Cantalamessa, delivered the homily and ended with a prayer that the pope recover quickly.
"Come back soon, Holy Father," he said. "Easter isn't Easter without you."
The 84-year-old pontiff's physical suffering has been evident for years as he battled Parkinson's disease and crippling hip and knee ailments. But it has worsened with the effects of breathing problems that prompted two hospitalizations in a month and added poignancy to the Holy Week commemorations.
Meanwhile, the obviously failing health of Pope John Paul II has given new impetus to the Vatican press corps' favorite preoccupation, compiling lists of possible successors, reports.
John Paul has been absent for the major events of Holy Week, although he has appeared silently at his studio window twice this week and has delivered messages telling the faithful that he is spiritually near them as he recovers.
"It's very obvious that the pope is carrying a very heavy cross indeed, and he is giving a marvelous example of patience in the face of suffering, and of long suffering which in itself is a virtue," a top Vatican official, U.S. Archbishop John Foley, told Vatican Radio on Friday.
The pope hasn't spoken in public since shortly before he was released from the hospital March 13, and his only commitment during Holy Week is to deliver a blessing on Easter Sunday.
