VATICAN CITY — Declaring that he lacks the strength to do his job, Pope Benedict XVI announced Monday he will resign Feb. 28 — becoming the first pontiff to step down in 600 years. His decision sets the stage for a mid-March conclave to elect a new leader for a Catholic Church in deep turmoil.
The 85-year-old pope dropped the bombshell in Latin during a meeting of Vatican cardinals, surprising even his closest collaborators even though he had made clear previously that he would step down if he became too old or infirm to carry on.
Benedict called his choice "a decision of great importance for the life of the church."
Indeed, the move allows the Vatican to hold a conclave before Easter to elect a new pope, since the traditional nine days of mourning that would follow the death of a pope doesn't have to be observed.
It will also allow Benedict to hold great sway over the choice of his successor, though he will not vote. He has already hand-picked the bulk of the College of Cardinals — the princes of the church who will elect the next pope — to guarantee his conservative legacy and ensure an orthodox future for the church.
"Without doubt this is a historic moment," said Cardinal Christoph Schoenborn, a protege and former theology student of Benedict's who himself is considered a papal contender. "Right now, 1.2 billion Catholics the world over are holding their breath."
Cardinal Andre Vingt-Trois, the archbishop of Paris, called the decision a "liberating act for the future," saying popes from now on will no longer feel compelled to stay on until their death.
"One could say that in a certain manner, Pope Benedict XVI broke a taboo," he told reporters in Paris.
There are several papal contenders in the wings, but no obvious front-runner — the same situation when Benedict was elected pontiff in 2005 after the death of Pope John Paul II.
The Vatican stressed that no specific medical condition prompted Benedict's decision, that he remained fully lucid and took his decision independently.
"Any interference or intervention is alien to his style," Vatican spokesman the Rev. Federico Lombardi said.
It has been obvious to all that the pope has slowed down significantly in recent years, cutting back his foreign travel and limiting his audiences. He now goes to and from the altar in St. Peter's Basilica on a moving platform to spare him the long walk down the aisle. Occasionally he uses a cane.
His 89-year-old brother, Georg Ratzinger, said doctors had recently advised the pope not to take any more trans-Atlantic trips.
"His age is weighing on him," Ratzinger told the dpa news agency. "At this age, my brother wants more rest."
Benedict emphasized that carrying out the duties of being pope requires "both strength of mind and body."
"After having repeatedly examined my conscience before God, I have come to the certainty that my strengths due to an advanced age are no longer suited" to the demands of being the pope, he told the cardinals.
