An 85-year-old priest has had his throat cut by an Islamic fanatic while saying Mass in a church in Normandy. For people in the West, this is a scene of almost unimaginable horror. Catholics in particular will be revolted and profoundly disturbed by a bloody killing perpetrated during the act of holy sacrifice around which our faith is built.

Catholics in the West, that is. For Catholics and other Christians in the Middle East, the atrocity at Saint-Étienne-du-Rouvray is far from unimaginable. They have been living with this sort of terror for years, while Western politicians and the liberal commentariat looked away.
