One after another, news reports about violence at Catholic churches in France kept stacking up.

There was a mysterious fire on a church altar in Provence. Elsewhere, someone attacked the tabernacle containing the unleavened bread used in the Mass, scattering hosts on the floor. Attackers destroyed crosses and crucifixes in graveyards.

None of this surprised the Pro Europa Christiana Federation, which collects French media reports on anti-Christian acts of this kind. In 2015 they found 810 similar attacks in France.

But the murder of Father Jacques Hamel was different. The attackers interrupted a Mass, shouting "Allahu Akbar" and references to the Islamic State. The duo forced the elderly priest to kneel at the altar, where they slit his throat in what may have been an attempted beheading.

A nun who escaped -- Sister Danielle -- told reporters: "They told me, 'you Christians, you kill us.' They forced him to his knees. … That's when the tragedy happened. They recorded themselves. They did a sort of sermon around the altar, in Arabic. It's a horror."

This drama unfolded in the church of Saint-Etienne-du-Rouvray, named for St. Stephen, the first Christian martyr, noted Archbishop Anthony Fisher of Australia, during a "Mass In Time Of Persecution" in Sydney.

"Though we welcome the solidarity of those of other faiths, and while we recognize that this was very much an attack on France, on civilization, on all religions more generally, we cannot ignore the fact that this was also a targeted attack on our Christian faith," he said.
