Archbishop Pier Luigi Celata, vice chamberlain, reads a copy of a document signed by Pope Benedict XVI at the Vatican on Monday, Feb. 25, 2013. Pope Benedict XVI has changed the rules of the conclave that will elect his successor, allowing cardinals to move up the start date if all of them arrive in Rome before the usual 15-day transition between pontificates. Benedict signed a legal document, issued Monday, with some line-by-line changes to the 1996 Vatican law governing the election of a new pope. It is one of his last acts as pope before resigning Thursday.
