Pope Francis did say that if someone insults your mother (i.e. the Church) you are allowed to punch him in the face.

Frank the Fraud said “If my good friend Dr Gasparri says a curse word against my mother, he can expect a punch,” in defending the mohammadeans in the (probable fαℓѕє fℓαg) Charlie Hebdo attacks. Poche has read the mind of a heretic and "divined" that he was macholy encouraging physically defending the church from insult. If you want the amusement of seeing one who is "light in his loafers" feign a punch, there is video of the statement too.
