"Satan is not a being, but is rather the influences we have compelling us toward that which goes counter to G-dās Will. These influences are called the āyetzer haraā (evil inclination), otherwise known as Satan, not because Satan is evil, but because these influences drive a person to desire that which is evil.
The yetzer hara will do itās job but it does not want to succeed. It wants us to succeed in not succumbing, yet most of us fail dismally. Those who do not fail are diamonds in the eyes of G-d.
As to the fallen angel Lucifer of Yeshayahu (Isaiah) 14:12, it is a Christian misunderstanding of the text. Hailail, the name in the text, and not Lucifer (there is no Lucifer anywhere in Hebrew Scripture), is the morning starā¦VENUS. People would rise at dawn and see one lonely star in the sky, and some assume, in error, that the star had fallen from the Heavens, and the myth of the rebelling angel was born. Hailail is Venus, which can still be seen on certain mornings long after all the other stars have tucked themselves away."
From here, which explains much better than I can.
Ask the Rabbi, JewishAnswers.org Ā» The Jewish View of Satan
While that is the position of most branches of Judaism.
It excludes messianic Judaism.
Remember that the Christian faith actually was a sect, of Hebrews, and all of the new Testament was authored by Hebrew men except the two volume book Luke/Acts... who was a "ger" and personally trained by Jesus.
In the gospel of Mathew (which btw was originally penned in Hebrew, for Jewish readers) Satan and Jesus had an encounter.
This was right after Jesus was baptized on the Jordan river by his cousin John the Baptist.
The encounter is between two beings. They talk to each other, and one picks up and carries the other, ( in flight no less ).
Within Christianity the Devil is a synonym for Satan, and vice versa.
One name means "adversary" (also enemy)
The other means "slanderer" (or "the accuser).
Jesus refers to him as "the Father of lies".
It's no big leap to go from accusing adversary to slandering adversary.
The point is the New Testament refers to this being in the male pronoun "he".
The New Testament identifies his fall, his current activities, and his end.
In the bible, the most common synonym for "Satan" is "devil", which descends from Middle English devel, from Old English dÄofol, that in turn represents an early Germanic borrowing of Latin diabolus (also the source of "diabolical").
This in turn was borrowed from the Greek word diabolos "slanderer", from diaballein "to slander": dia- "across, through" + ballein "to hurl".
The Book of Revelation twice refers to "the dragon, that ancient serpent, who is called the devil and Satan" (12:9, 20:2)
About the identity of lucifer (aka Venus) in Christianity... please refer to the following for a full explaination.
Lucifer was borrowed from the Latin translation of the Hebrew OT aka Tanakh, that was performed by Jerome (which was called the Vulgate).
I already the lucifer was VENUS.
During the fourth century when Jerome was translating from the the Hebrew scriptures (what few he had) and Greek translation aka the Septuagint to the Latin of the Vulgate, the planet
Venus was called Lucifer. It was called the same in Roman Astrology and Astronomy.
So we see that Jerome made a logical choice of wording in this particular passage and timeframe to associate Isaiah 14:12 with the morning star Venus.
In the original Hebrew the reference is to
Heylel ben Shachar. The first Hebrew word Heylel
means morning star, literally the planet Venus; from the root word halal
meaning to shine or give light, also quite appropriately,
to boast . The second word, ben, means son (of).
Shachar translates
generally to morning, or properly to dawn.
Also of note, the Roman Catholic Church says : the Father maintain that Lucifer is not the proper name of the Devil but denotes only the state from which he has fallen (Petavius,
De Angelis, III, iii, 4).
Is Lucifer Satan? Does the fall of Lucifer describe Satan?
