VATICAN CITY — 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. The Vatican spokesman, the Rev. Federico Lombardi, said Benedict himself had made the decision in consultation with others, settling on “Your Holiness Benedict XVI” and either emeritus pope or emeritus Roman pontiff. Lombardi said he didn't know why Benedict had decided to drop his other main title: bishop of Rome. In the two weeks since Benedict's resignation announcement, Vatican officials had suggested that Benedict would likely resume wearing the traditional black garb of a cleric and would use the title “emeritus bishop of Rome” so as to not create confusion with the future pope. Benedict's decision to call himself emeritus pope and to keep wearing white is sure to fan concern voiced privately by some cardinals about the awkward reality of having two popes, both living within the Vatican walls. Adding to the concern is that Benedict's trusted secretary, Monsignor Georg Gaenswein, will be serving both pontiffs — living with Benedict at the monastery inside the Vatican and keeping his day job as prefect of the new pope's household. Asked about the potential conflicts, Lombardi was defensive, saying the decisions had been clearly reasoned and were likely chosen for the sake of simplicity. “I believe it was well thought out,” he said. Benedict himself has made clear he is retiring to a lifetime of prayer and meditation “hidden from the world.” However, he still will be very present in the tiny Vatican city-state, where his new home is right next door to the Vatican Radio and has a lovely view of the dome of St. Peter's Basilica. While he will no longer wear his trademark red shoes, Benedict has taken a liking to a pair of hand-crafted brown loafers made for him by artisans in Leon, Mexico, and given to him during his 2012 visit. He will wear those in retirement, Lombardi said. — AP
