When I pointed out that Jesus is an important religious figure to both Islam and Christianity, the Christians become outraged. I'm curious why that is. When I pointed out that the Old Testament, written in Hebrew and Aramaic, is almost completely Jewish. And since Jesus was supposedly Jewish, why do Christians get upset when it's mentioned that religious figure is also a prophet of Islam? 10 brief points Christians should know about Muslims and Jesus Muslims believe that Jesus was born miraculously of a virgin mother and no father. Jesus will return before the end of the world. It's perfectly clear that I have no "mystical" beliefs. I view Judaism, Islam and Christianity as very similar. All religions claim theirs is a religion of "peace". Until you read stuff like: Jeremiah 48:10 NAB Cursed be he who does the Lords work remissly, cursed he who holds back his sword from blood. I know from the violence of the Old Testament, Jews aren't any more peaceful and in the Koran, it's almost a study of violence and torture. The bottom line, all three religions hate being compared to the other two. Why is that?
