On Tuesday, the so-called Islamic State released a slickly produced video showing a Jordanian pilot being burned alive in a steel cage. On Wednesday, the United Nations issued a report detailing various “mass executions of boys, as well as reports of beheadings, crucifixions of children and burying children alive” at the hands of the Islamic State. And on Thursday, President Barack Obama seized the opportunity of the National Prayer Breakfast to forthrightly criticize the “terrible deeds” ... committed “in the name of Christ.”
