Sibling says pope may keep going by Benedict XVI
Pontiff set to step down next week21 February, 11:03
"I think he will continue to call himself Benedict XVI," Father Georg Ratzinger, a priest in Regensburg, told Corriere della Sera.
The outgoing pope was born Joseph Aloisius Ratzinger and took the name Benedict XVI when he was elected to the helm of the Catholic Church in 2005.
Vatican Spokesman Father Federico Lombardi has said a new title may have to be coined to refer to Benedict once he officially steps down.
"It will be interesting to see how we address him, how he will be called," said Lombardi. "It will be difficult to call him cardinal".
