@bulmabriefs144,
Judaism, Christianity, and Islam describes religion that responds to the same god and have various forks of the same religion.
Judaism does not accept Christ because of the Roman empire usage of Christ. You have to think about the time-line and how life was via
Old Rome
New Rome
Post Rome
Renaissance
Dark Ages
Midevil Times
Enlightenment
Age of Exploration
Etc.
During through those hundreds, upon possible thousands of years Jews was still seen as the enemy ( even today for other reasons ). The Romans went from Evangelism into Christianity. With the biblical recordings alongside historical events. Most of these recordings itself could also be traced to various belief systems including the Greek idea of God or Roman idea of Goddesses ( which were all representations and mistranslations ).
Again Jews was attacked for not accepting Christ.
Islam on the other-hand did accept Christ as a prophet. Also through that transitional period much of Europe has much to be thank from Islamic scholars, students, and educators in terms of the Mathematics. But again Europe was much of a forced empire ( forcing people to get along ) and beyond that came ideas of ethnic cleansing.
Those Jews was about survival and the reality that they were enslaved and if any that came to power was in a type of Chinese-checkers warfare, just to preserve Jews within Europe and the world.
The reality we are in same stupidity from then.
Christian X ( Being consistent of the Roman Empire and Greeks ) v. Judiasm X ( Being between Africa, and Asia ) v. Islamic X ( Ottoman Empire consisting of trade routes like the Silk Road ), v Han X ( Mainland China empire ).
It is like Chinese-Checkers ( that game we played as children ).
.....................................................
Again
Judaism rejects anything that is Rome including Christ because many of the recordings and writings are questionable along with the fact that Islam accepts Christ as a prophet.
That being said beyond the Judo-Christian age, many modern Jews do accept Christ being real, but again it is a problem with education ( brainwashing ) rather then accepting Muhammad. So it would make sense not to accept Muhammad as a prophet. Especially with the history involved.
Muhammad came to "power" only when a city was under attack. If those leaders knew what they were doing then he would have not came to any form of military leadership at all.
You have to look at young Muhammad and what he was exposed to.
You have to look at any history of religion in general.
You have to think what was going through his mind.
A great example is that film "Life of Pie". The kid was exposed to so many religions, and so many advances and changes of society around him. Put that into your mind and then put the fact that whatever Muhammad was doing ( actually gaining followers ) .
Again parts of Islam existed before Muhammad.
.............
Do not look at Muhammad and the sword. That was an accident. That was somebody falling into power due to circumstances. Look at Muhammad the seeker of truth. Look at him like Mosses, Jesus, Abraham, Elisha, Joseph, or any other prophet.
