(By Christopher Livesay) (ANSA) - Vatican City, March 8 - The conclave to elect the next pope will start Tuesday, March 12, the Vatican announced Friday. "The eighth General Congregation of the College of Cardinals has decided that the Conclave for the election of the Pope will begin on Tuesday, 12 March 2013," said a statement. The conclave to elect the 266th pontiff follows the shocking resignation of Benedict XVI, who on February 28 became the first pope to abdicate in 600 years. Next week on Tuesday morning, cardinals will celebrate a pre-conclave mass known as the pro eligendo Summo Pontefice asking God to enlighten them. That afternoon, they will enter the Sistine Chapel for the start of the conclave. Some analysts have predicted that a new pope may emerge by the end of the week.
