What, in the name of God?

It is a question that demands asking, that haunts this most recent atrocity.

Ordinarily, it is only rhetorical, something you might say if you came home to find police cars parked in front of your house. But it takes on a painful literalness following the latest video from the Islamic State, or ISIS, the barbarian army of extremists that has swept through Syria and Iraq.

What, in the name of God?

The answer is bitterly simple. They killed Peter Kassig, that’s what. They lopped off his head and displayed the results on a new video. This, supposedly, on God’s behalf.

No, neither the decapitation nor the video is a first. We still grieve Daniel Pearl, the Wall Street Journal reporter beheaded in Pakistan 12 years ago. More recently, ISIS has made this sort of murder porn ubiquitous.

Other known victims include James Foley and Steven Sotloff, both American journalists, David Haines and Alan Henning, both British aid workers, Herve Gourdel, a French hiker, and many others, including soldiers from Syria and Lebanon. Each was someone’s child and each, presumably, left a hole in someone’s life.

But the story of Peter Kassig, the sad courage with which his parents spoke to the world this week upon the death of their only child, suggests something that seems to need saying in the face of all this grisly cruelty, something about the things we do in God’s name.

Kassig, who was 26, first went to the Middle East as an Army Ranger. He returned as a volunteer after his discharge to use his skills as a medical technician to treat victims of Syria’s civil war. Why would he do this? Because he felt a call. Because it needed doing.

As he told CNN in 2012, “We each get one life, and that’s it. You get one shot at this. You don’t get any do-overs. For me, it was time to put up or shut up. The way I saw it, I didn’t have a choice. This is what I was put here to do. I guess I’m just a hopeless romantic and I’m an idealist, and I believe in hopeless causes.” Or, just a man who believed in something larger than his own life.

Monday, in the wake of his death, his parents, Paula and Ed, met the media at their longtime church in Indianapolis and you could see where he got it from.

They called him Abdul-Rahman, the name he took upon his conversion to Islam. His father quoted Jesus’ admonition from the book of John: “Greater love hath no man than this: to lay down his life for another.” His mother said with an assurance that lifted you as tides lift boats, “Our hearts are battered, but they will mend. The world is broken, but it will be healed in the end and good will prevail as the one God of many names will prevail.” His father asked for prayer. He said the family would “mourn, cry, and yes, forgive.”

“Forgive,” he said. It is arguably the most difficult dictate of faith. No one would blame them if they didn’t even try. But they say they will.

What, in the name of God?

In 1862, mired in America’s most ruinous war, Abraham Lincoln mused on God’s role in the tragedy. “In great contests,” he wrote, “each party claims to act in accordance with the will of God. Both may be and one must be wrong. God cannot be for and against the same thing at the same time.”

The observation feels freshly relevant as you juxtapose the bloody charnel house of the Middle East with the quiet faith of one family from the Upper Midwest.

What in the name of God?

Well, ISIS commits murder.

But the Kassig family is driven to serve strangers halfway around the world, to whisper hope in the midst of nightmare, forgiveness in the unendurable moment. And to seek prayer.

“Both may be and one must be wrong,” said Lincoln. He was right. And one is.
