Exactly.
The Biblical scriptures (scrolls) explain the role of Lucifer/Helal (shining one), Satan (Ha Shatan / the accusor), Legion (the many) in several different places.
There is, of course, as has been pointed out, what jews believe, and there is on the other hand what the scriptures say, and as east is east, and west is west, nary the twain shall meet.
Jesus (Jeshua) of Nazareth tried to set the jews straight, regarding their many erroneous doctrines, for which he earned their hatred. According to the New Testament authors, they were worried that he would destroy their roles. Among their own community, that never really happened. Christianity took root mostly in Greece and Rome, then on from there to the non-semitic nations of Europe.
I am not real interested in whatever jews believe, especially when it contradicts the Biblical scriptures. Jews can profess that there is no Lucifer/Satan/Legion, however the Biblical scriptures state otherwise in many places.
Arguments that attack others personally, using words like "fanatic," are satanic arguments.
Arguments that interpose science or philosophy as contradictory to religion are also satanic.
Philosophy and other such intellectualization serve the forensic purposes of discovery and debate, but do not provide anything regarding religion.
Science explains observations with theories and ideas, but has no relationship to religion at all. Those who argue that science "proves" religion to be wrong are using satanic arguments. I am sure Lucifer/Satan/Legion loves all of you who do this, and I suspect he will come calling later to collect his "friends."
Religion is a testimonial witnessing by prophets, seers, and revelators, to explain why, not how. You are free to believe the prophets, or you may not.
But you won't ever get very far arguing about it. And especially not, whenever you utilize satanic arguments.
