A little bit of Latin always raises the tone of an article, so here (thanks to the classical correspondent of The Observer) is a sentence that may prove useful to Pope Francis: "agite tentaque si fortiores vos putatis." It means "come on then, if you think you're hard enough."

It's the manly thing to say if you have just punched somebody, and he looks like he's thinking of hitting you back.

Francis has recently expressed the view that "if anyone says a curse word against my mother, he can expect a punch." So he should be ready for some retaliation, and saying that in Latin might deter the victim from hitting the supreme pontiff back.
