Pope Benedict XVI will be known as "emeritus pope" in his retirement and will continue to wear a white cassock, the Vatican announced Tuesday, again fueling concerns about potential conflicts arising from having both a reigning and a retired pope.The pope's title and what he would wear have been a major source of speculation ever since Benedict stunned the world and announced he would resign on Thursday, the first pontiff to do so in 600 years.
