" My experience at Trinity points up one big difference between Islam and Christianity: Islam shuns a critique of the Quran. If you ask the hard questions of the Quran, you risk being branded, and, in some cases, you even risk your life. The Christian, however, has always been willing to subject the Bible to the severest analysis and is able to come out, knowing that it can survive the blade of the skeptic. "
