Medieval theology is the antidote to the Islamic State’s religious ideology

In the face of ...bloody chaos, the proponents of irja said that the burning question of who is a true Muslim should be “postponed” until the afterlife. Aware that irja is its theological antidote, the Islamic State presents it as a lack of religious piety. It is, however, true piety combined with humility — the humility that comes from honoring God as the only judge of men. On the other hand, the Islamic State’s zeal to dictate, which it presents as piety, seems to be driven by arrogance — the arrogance of judging all other men, and claiming power over them, in the name of God.
