Yes, the difference is huge. In Christianity, Jesus is God and part of the three-part Godhead. In Islam he is a prophet or messenger, not considered part of the Trinity, or to be God. In Christianity, Jesus died and rose form the dead as a means of restoring the relationship between sinful man and a righteous God. Islam rejects this.
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.
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.
Christianity: Son of God (Messiah) Islam: Prophet Judaism: False messiah
Even though Christians and Islamic peoples have the same god (with different names), The biggest difference between Islam and Christianity is that Christianity dictates that Jesus Christ to be the savior of all Mankind, where as Islam does not. There are also disputes over who was and was not a prophet, canonized scripture (the Koran as opposed to the Bible) and other beliefs.
Christianity and Islam have similar religious roots in the Middle East although what was believed about individual characters represented may diverge very greatly. For example, in Christianity Jesus is the savior, but in Islam he is a prophet.
Christianity teaches that Jesus is the son of God, or God himself. Islam teaches that Jesus and Muhammad were prophets of God.
Apart from Christianity Jesus is also a prophet in Islam.
Protestantism is part a type of Christianity, though Christianity and Islam are in some ways, similar. The main difference is about Jesus (Muslims believe is a prophet, not the Son of God, like in Christianity). Protestantism believes in simplicity and, in some ways, so does Islam. However, Muslim mosques are quite elaborate, whereas in Protestantism, they are very plain.
Islam began when the Prophet Muhammad received a vision from God, encouraging him to spread a divergent system of beliefs. The main difference between Christianity and Islam is that Muslims don't believe that Jesus was the son of God. However, unlike Judaism, they do believe he was a prophet divinely gifted by God. Beyond that, Muslims and Christians have many of the same central beliefs.
Islam Proves that the Chritainity of these days are not the one of Jesus
Christians believe Jesus is part of the Holy Trinity. Muslims believe Jesus was a prophet.
Islam. In Islam, Jesus is generally referred to as "al-Masīḥ", which means "the Messiah". The stories about Jesus differ between Christianity and Islam however. In the Christian version, Jesus is a healer who died for people's sins. In the Muslim version he is a bringer of new scripture.
