David P. Goldman contrasts what sets the Judeo-Christian religions apart from Islam. A couple of excerpts:
Religious war of conquest, that is, jihad, has the same role in Islam that the Lord’s Supper has in Christianity. Christianity (and Judaism) have exercised violence in the past but never sacralized violence. That is unique to Islam among the self-styled Mosaic religions.

It is important to get the theology right — not so much to understand the depredations of radical Islam, which hardly are obscure, but to understand what makes the West different. Violence is incidental to Judaism and Christianity and fundamental to Islam. ...

There is no Grace in Islam, no miracle, no expiatory sacrifice, no expression of love for mankind such that each Muslim need not be a sacrifice.

Jihad is the precise equivalent of the Lord’s Supper in Christianity and the Jewish Sabbath, the defining expression of sacrifice that opens the prospect of eternity to the mortal believer. To ask Islam to become moderate, to reform, to become a peaceful religion of personal conscience is the precise equivalent of asking Catholics to abolish Mass.Read it all.
