So the koran factually has no historicity at all for Jesus or Israelite cultures, correct?
It has some interpretations of history,
and it has some interpretations of Jewish and Christian doctrines,
but the Qur'an is not a history book,
and I do not know of it saying anything about any culture - of course other people could interpret things about culture.
For myself human culture is not interesting, and it is mostly very boring.
I go to the Qur'an and the Bible and other scriptures to learn about life and about God
Non sequitur to the question.
Thank God I am not bound (not sequitured) to your question(s).
You do not get to define the parameters for my comments.
Why would you think the koran has information about god if it was plagiarized from biblical text?
It is not plagiarized - it is a continuation.
Religious scriptures do not have patent or copy right infringements.
The real God welcomes people to use His words as a gift and not as a theft.
And why would you use the bible to learn a one sided version of gods? is that not admitting divine origin?
Divine origin does not have to mean infallibility or literal or any such restriction - except lie - God does not lie.
That is the way to judge the scriptures by deciphering what is a lie and what is truly Divine.
The Bible itself is not divine - but it does have divine inspiration.
I do not even see how the Bible can be called as one-sided, but we can use other scriptures like the Holy Qur'an to help see other sides.
