When I wrote of barbarism yesterday I didn’t yet know about the slayings in Jerusalem. This time terrorism has reached much farther than Indiana. It has reached into the sanctuary itself.

It is difficult to measure grief and outrage, but this incident is striking in its brutality. The piousness of the victims, their vulnerability, the contested city in which these slayings took place — a city riven by religious violence.

I looked up how often murders occur in places of worship and found a Christian Science Monitor article reporting that as of last June there had been 780 deadly attacks in U.S. churches in the last 15 years, according to Carl Chinn, a church security expert who was himself a victim of church violence. Such violence was almost nonexistent before the bombing at the 16th Street Baptist Church in Birmingham, Alabama, in 1963, Chinn said.

The numbers worldwide are much bigger and more horrifying, I’m sure.

Religious-based violence is nothing new. But the ironies are too great to ignore. That a force intended for good has been hijacked for evil. That a place built for sanctuary has become a killing ground.
