Vatican City: Roman Catholic Cardinals begin a conclave on Tuesday to elect the Church's 266th pontiff and a successor to Pope Benedict, who abdicated unexpectedly in February. The 115 cardinal electors under the age of 80 prayed for divine help on Tuesday, hours before entering the frescoed Sistine Chapel on Tuesday afternoon.
They will hold one vote that evening and vote up to four times day thereafter until one of their number receives a two-thirds majority, or 77 votes. No conclave has lasted more than five days in the past century.
Pope Benedict was elected within barely 24 hours in 2005 after just four rounds of voting. But this time, no clear favourites have emerged to take the helm of the troubled Church.
The cardinal electors have drawn lots for the rooms and suites in Santa Martha, a modern residence which is being used only for the second time to house conclave participants. The first time was in 2005. The secret conclave, steeped in ritual and prayer, could carry on for several days, with no clear favourite in sight. In a process dating back to medieval times, the "Princes of the Church" from 48 countries will shut themselves in the Vatican's frescoed Sistine Chapel.
They will emerge from their seclusion only when they have chosen the 266th pontiff in the 2,000-year-history of the Church, which is beset by sex abuse scandals, bureaucratic infighting, financial difficulties and the rise of secularism.
"We are ready to enter the conclave and it will be longer than the last one," South African Cardinal Wilfrid Fox Napier told reporters on Monday, referring to the 2005 election of Benedict, that was wrapped up in 24 hours after four ballots.
"It will last a few days. Maybe four or five," he predicted. The average length of the last nine conclaves was just over three days and none went on for more than five days. Vatican insiders say Italy's Angelo Scola and Brazil's Odilo Scherer have emerged as the men to beat. The former would bring the papacy back to Italy for the first time in 35 years, while the latter would be the first non-European pope in 1,300 years.
However, a host of other candidates from numerous nations have also been mentioned, including US cardinals Timothy Dolan and Sean O'Malley, Canada's Marc Ouellet and Argentina's Leonardo Sandri.
All the red-hatted prelates who will be secluded in the Sistine Chapel were appointed by either Benedict or his predecessor John Paul, and the next pontiff will almost certainly pursue their fierce defence of traditional moral teachings.
But Benedict and John Paul were criticised for failing to reform Vatican bureaucracy, battered by allegations of intrigue and incompetence, and some churchmen believe the next pope must be a good manager or put a good management team in place.
Vatican insiders say Scola, who has managed two big Italian dioceses, might be best placed to understand the Byzantine politics of the Vatican administration - of which he is not a part - and therefore be able to introduce swift reform.
The Curia faction, of cardinals working inside the Vatican bureaucracy, is said by the same insiders to back Scherer who worked in the Vatican's Congregation for Bishops for seven years before later leading Brazil's Sao Paolo diocese - the largest diocese in the biggest Catholic country.
With only 24 per cent of Catholics living in Europe, pressure is growing within the Church to choose a pontiff from elsewhere in the world who would bring a different perspective. Latin American cardinals might worry more about poverty and the rise of evangelical churches than questions of materialism and sexual abuse that dominate in the West, while the growth of Islam is a major concern for the Church in Africa and Asia.
The cardinals are expected to hold their first vote late on Tuesday afternoon, which is almost certain to be inconclusive, before retiring to the Vatican hotel for the night. They hold four ballots a day from Wednesday until one man has won a two-thirds majority - or 77 votes. Black smoke from a makeshift chimney on the roof of the Sistine Chapel will signify no-one has been elected while white smoke and the pealing of St Peter's bells will announce the arrival of a new pontiff.
As in medieval times, the cardinals will be banned from communicating with the outside world. The Vatican has also taken high-tech measures to ensure secrecy in the 21st century, including electronic jamming devices to prevent eavesdropping.
