As I said at the beginning, I don’t have the expertise to know whether Luxenberg is right or wrong. But I do know that there are parts of the Koran that are shockingly contradictory—and Luxenberg’s theory is certainly thought provoking. If Luxenberg is right, Islam is built on at best a severe misreading—and at worst, a cynical manipulation by Arab political leaders more than a thousand years ago. It would certainly force a great many Muslims to rethink their faith—and wonder if Mohammed was actually trying to Christianize the polytheistic desert dwellers of Arabia.
