In Case you were Wondering What to Call Benedict XVI
Via the BBC: Benedict XVI to be known as ‘pope emeritus’
Benedict XVI will be known as "pope emeritus" and will retain the honorific "His Holiness" after he abdicates on Thursday, Vatican official say.
He will also continue to be known by his papal title of Benedict XVI, rather than reverting to Josef Ratzinger.
He will wear his distinctive white cassock without any cape or trimmings.
He will surrender his gold ring of office, known as the fisherman’s ring, and his personal seal will be destroyed in the same way as when a pope dies.
My favorite bit:
Benedict XVI will also give up wearing his specially-made red leather loafers, instead wearing brown shoes hand made for him by a Mexican craftsman during a brief visit to Mexico last year, Vatican spokesman Federico Lombardi said on Tuesday.
I am guessing that he does not get to continue using the Popemobile, however.
