The Pope has been sensationally quoted as saying hell does not exist and souls not worthy of heaven merely disappear instead of being tormented.
But the Vatican quickly denied the apparent dramatic theological shift, accusing atheist reporter Eugenio Scalfari of "reconstructing" his words.
Catholic teaching dictates that "immediately after death the souls of those who die in a state of mortal sin descend into hell".
Scalfari, 93, in his fifth interview of Pope Francis published in the La Repubblica newspaper, asked what happened to "bad souls" after their bodies died.
"They are not punished, those who repent obtain the forgiveness of God and enter the rank of souls who contemplate him, but those who do not repent and cannot therefore be forgiven disappear," he quoted the Pope as replying.
