I think this is the most succinct definition of the "religion of peace" I've yet come across. From the Melkite Greek Catholic Archbishop Cyril Salim Bustros-

"While Islam has many different interpretations and no central arbiter of doctrine, such as the pope, most Muslims are taught to interpret the Quran literally. Following its precepts, they divide the world into Dar al Islam and Dar al Harb — the land of peace and the land of war, the land conquered by Muslims and the land yet to be conquered by Muslims.

Like Christians, Muslims are obligated to "convert nonbelievers." Unlike Christianity, however, "the doctrines of Islam dictate war against unbelievers." Jihad, or holy war, is justified as self-defense whenever Islam is threatened — be it by a conquering power or an offensive cartoon.

Most Muslims do not take those interpretations of the Hadith, or Islamic teaching, as far as Osama bin Laden and the Taliban, Archbishop Bustros said. But the fact is that "the concept of nonviolence is absent from Muslim doctrine and practice."

Although Islam calls itself a religion of peace, the peace it preaches is the literal interpretation of Islam, which means "surrender to the will of God."

"The peace in Islam is based on the surrender of all people to Islam and to God's power based on Islamic law," Archbishop Bustros said. "They have to defend this peace of God even by force."
