"But for Muslim teaching, God is absolutely transcendent. His will is not bound up with any of our categories, even that of rationality"
The religion of Islam has at its center a God that is not bound to reason, morality or anything. The result is chaos and death, imposition of will as an end unto itself. Per Pope Benedict the problem begins in their conception of a God without reason.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." -Manuel II Paleologus
