After a mass at which they were urged to find a good shepherd for their church, 115 Roman Catholic cardinals are now prepared to begin the formal process of selecting the next pope.
If all goes as planned, the princes of the church (who NPR's Philip Reeves profiled on Morning Edition), will vote once Tuesday afternoon during their conclave in the Sistine Chapel. It's not expected that one candidate from their ranks will receive the two-thirds necessary (77 votes) to become pope. So it's likely that Tuesday evening in Rome (mid-afternoon along the East Coast of the U.S.) we'll see black smoke coming from a special chimney atop the Vatican — black is the signal that there's been a vote, but no decision; white smoke and bells chiming signal that a pope has been chosen.
As Phil explained Monday, in coming days the cardinals are expected to vote twice each morning and twice each afternoon until someone gets the two-thirds or more votes.
The conventional wisdom is that it may take several days for the cardinals to reach a decision. On Morning Edition today, NPR's Sylvia Poggioli said that while the cardinals won't be talking among each other and looking to build alliances while in the Sistine Chapel, they will almost surely "be busy murmuring in each others' ears over coffee and pasta" when they take breaks.
That murmuring "could be the key to creating new alliances" that lead to the selection of a pope, Sylvia added.
As for which cardinals are being most talked about as potential popes, Sylvia says they continue to include Italian Cardinal Angelo Scola, 71, and Cardinal Odilo Pedro Scherer, 63, of Brazil.
We'll be watching for news from Vatican City and will update as it comes.
There are, of course, many other stories about the conclave today and many other ways to monitor what's happening:
There's "Vatican Player," the church's live webstream.
The Whispers in the Loggia blog continues its coverage.
The BBC rounds up the news so far today here, and writes that the homily the cardinals heard today "was more measured in tone than the address given in 2005 by Cardinal Joseph Ratzinger before he became Pope Benedict, which featured a fiery attack on the 'dictatorship of relativism.' "
