Edit.
Yes. True. They're -not- different in monotheism, results of practice, and disciplined devotion. Taking away the trinity part though thats critical to christianity but highly misinterpreted given the church politics.
Having no belief in god doesn't change the truth of these three religions. If I went off my views, I'd have different opinions about each.
Yes. Differences are cool.
They're not black and white differences but by no means the same purpose. Gosh. Human sacrifice alone at its basic core just putting the word Human in it creates a divide.
Bad and negative? No.
I can see how all three believe in the same god (nontrinatrians view). I just don't read they have the same purpose. Another thing is Islam and Judaism doesn't even define god (as so read). Christians do.
Bad? No. Not negative either.
How does Islam view jesus as the son of God?
Do they believe god has a son?
How does their belief about gods son similar to christians belief in gods son?
How is Islam similar to Christianity and Judaism? - IslamiCity
Here are some similarities and differences between the three faiths. A lot of things they have in common and the foundations they do not. But they do believe in the same god so I guess it depends what each religious wants to get out of the books.
As a non book person, I'd say if they all believe in the same god, their experiences would be the sole decided in who believes what and how. I don't think any muslim and jewish feels they need a human sacrifice to be saved. Christian practice are far and in between but most if not all don't see Need to pray five times a day as told muslims need to. As for jews, christians and muslims aren't chosen people so the similarities really depends on the person.
I don't see the benefit of finding similarities in scripture and theology rather than discussing with each other similarities in experiences and thoughts about god.
But, division isn't bad. I see more differences in Islam (especially it's history, my gosh) than similarities. But if we are talking about same god, charity, love, and devotion, they are similar.
Their are differences and there are similarities none worse than the other. If I knew more I'd do a thread on sharing experiences between the religious of these three faiths (if they talks that is) and find pick a tooth on similarities there. I'm sure even beyond stubbornness even though the theology conflicts if you guys believe the same god, the foundation of your experiences do not.
