Lucifer was Satan’s name, before he was cast out of heaven; he was one of God’s most favored angels.
He, in his pride, did not want to submit to human-beings. According to some traditions, God placed man above the angels.
Other traditions say he simply rebelled against God, because he wanted to be God himself and tried to overthrow him.
Would appear that he/she is just earthly and human.
We all operate differently at different times under our own skin.
So they’re archtypes or like avatars.
Is something REAL which only exists within our minds?
Pezer came out with an unexplected thought: that Lucifer is the Ugly Light, his name after he lost the title Luzbel. I have to meditate in this, is getting interesting. In any case he has nothing to do with Satan, this equating, equalizing of spirits is strictly interesting to barren psyches, treating life as some sort of analytical pseudo mathematics.
Satan as the adversary makes partial sense. But that woild clearly be a superficial term, revealing little of the nature of the adversity. Gravity might be called the adversary of the one who feels holy, as Trixie said. Her explanation is the only that stands out from what I can google so far, it helps that it is rooted in experience.
The most succinct description of Satan is “False Flag” - creating the perception of threat and framing someone/thing else. That is the “left hand”. The “right hand” is to provide the perception of hope against the perceived threat such as to profit. Satan is the [false] accuser.
If you carefully read the Old Testament in terms of its various cultural and historical influneces these three entities represent at least two different things.
For example…
“Satan” is God’s servant and does his bidding in Job.
In The Garden of Eden, the Serpent is not compatible with Satan, but always conflated with the “Devil”
But never forget that the whole thing is a fantasy.
I think that they are loosely the same, but different because it is a character glanced through the eyes of different authors. As such, Satan, a mere antagonist for the Hebrew evolved to become The Devil, the negative version of God. The state of the community from which the author emerged affected how the character was viewed. The evolution of Satan also reflects the different influences the Jews were exposed to. Ideas about the cosmic battle between Good versus Evil (Zoroastrianism) was assimilated into the Devil character.
