Based on countless Qur'anic verses and oral traditions attributed to Muhammad, Islam's learned officials, sheikhs, muftis, and imams throughout the ages have all reached consensus—binding on the entire Muslim community—that Islam is to be at perpetual war with the non-Muslim world until the former subsumes the latter.

Although Islam and Christianity seem to have certain points of doctrine in common, there is an enormous difference between them, not only in beliefs about salvation and Christ but in many other areas affecting daily life, human behavior and attitudes.

Does the Catholic Church teach that Christians and Muslims worship the same God? Matt Slick of the Christian Apologetics and Research Ministry (CARM) tries to answer the question but he's wrong about the Catholic position.

Are we witnessing today a phenomenon of nameless "religious extremists"—whether Christians, Jews or Muslims—spreading violence in the name of "religion"? Or is reality quite different? 

The purpose of my speech is to point out what the change in the relationship between Jews and Christians is about, and especially to show that in this change and in some prophetic events taking place in the world today between Christians and Jews, the heavenly Father is carrying out His plan in history looking more and more towards the day when Christ will return in glory to fulfill the Father's plan upon the world.

….In the meantime, Israel retains its own mission. Israel is in the hands of God, who will save it “as a whole” at the proper time, when the number of the Gentiles is complete….the evangelization of the Gentiles was now the disciples’ particular task…. (Benedict XVI, Jesus of Nazareth, Vol 2, pp. 44-46).

There has been much excellent academic study of the history of Christianity in the land of its birth. It could fill a whole library. In recent years, however, all that fine work has been eclipsed by the myth, created by the so-called "Palestinian narrative," of Palestinian Christianity.
