Islam and Christianity are both monotheistic religions. However the Christian religion does not identify Muhammad(s) as the last prophet or even a prophet. Islam recognizes Muhammad(s) as the last prophet and recognizes all the other God prophets that The Bible recognizes, including Adam, Noah, Abraham, Isac, Moses, David, etc.
In addition to the above:The two religions, Christianity and Islam, have in common all social values and principles of life. Both religions call for good deeds such as honesty, helping the poor, taking care of old people, to be nice and sympathetic with women and children, not spoiling the environment, to be kind with animals, not to kill without authority, not to steal, not to cheat, not to terrify the innocents, ... etc. These common social objectives of both religions should be acknowledged as important key to bring world societies to peace, love, and justice.
Both Islam and Christianity originated out of Judaism.
Christianity teaches that Jesus is the son of God. Islam teaches that Jesus was a messenger of God. Christianity teaches the concept of Original Sin. Islam does not. Islam teaches that Muhammad was a messenger of God. Christianity does not.
There is no war between Christianity and Islam. Some extremists in both groups are using religion for very ungoldy purposes.
The connection between Islam, Christianity and Judaism is that the three religions trace their history to the covenant between God and Abraham.
Christianity is older than Islam.
The difference between between these three religions: Christianity, Judaism, Islam and Hinduism is in the death and resurrection of Jesus Christ, the founder of Christianity. This single event marks Christianity different from these other religions.
Hinduism is oldest, followed by Judaism, Buddhism, Christianity, and then Islam.
Islam is a religion. So, sure there is no relation between a person name and the religion.
The question should be " What does Christianity have to do with Jews (or Judaism)?" Judaism is like a tree where Christianity is its branch and Islam is it leaves. Christianity is based on Judaism and Islam is based on Christianity. The major difference between the three is that Judaism doesn't have jesus in it unlike Christianity and Islam.
