Criminey. I have never heard of any Christians who don't firmly avow that they worship the one creator God of the Bible, including the scriptures recognized by the Jews which constitute the "Old Testament" of the Christian Bible. The Islamic faith recognizes Jesus as a prophet, prior to Mohammed, of the same God they worship. Does that sound like it's just a matter of linguistics? The claim by some Christians that Allah is a different god is nothing more than an effort to demonize Muslims.
