Do tell, using scripture, how you come to this conclusion, or whatever proof you have to support your theory.
I will gladly use just Scripture. First we will explore the story of Balaam.
Numbers 22:22 said:
And God's anger was kindled because he went: and the angel of the LORD stood in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him.
The relevant words will be highlighted in the Hebrew as well for you. Please feel free to use any concordance you like, or ask a Jewish person for help.
Askmoses.com - Torah, Judaism and Jewish Info - Ask the Rabbi boasts a live chat in which you can ask a Rabbi personally to translate these words. You do not need to take my word for it.
Numbers 22:22 said:
וַיִּֽחַר־אַ֣ף אֱלֹהִים֮ כִּֽי־הֹולֵ֣ךְ הוּא֒ וַיִּתְיַצֵּ֞ב מַלְאַ֧ךְ יְהוָ֛ה בַּדֶּ֖רֶךְ לְשָׂטָ֣ן לֹ֑ו וְהוּא֙ רֹכֵ֣ב עַל־אֲתֹנֹ֔ו וּשְׁנֵ֥י נְעָרָ֖יו עִמֹּֽו׃
Hebrew is read from right-to-left. If you do not mind, I will follow this convention as I speak on the Hebrew present here.
The first word I have highlighted is the same as the first word I have highlighted in the English. It is read "Malach". This word is usually used when referencing an angel and implies subservience. Malach, which can also mean messenger, means angel and means one is beneath another authority.
The second & third word I have highlighted are the same as the second word I have highlighted in the English. It's actually part of a verb structure. It is read (all together) "l'satan lo". This verb structure means "provoke" or "oppose".
In this story, God is angry and thus created or called forth an angel to act as a Satan, or an adversary, to oppose Balaam.
For our second example we'll look at the story of Job. Here we'll see how Satan is used as a noun, instead of a verb, which is usually translated as "provocateur", or "adversary".
Job 1:6 said:
Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them.
Job 1:6 said:
וַיְהִ֣י הַיֹּ֔ום וַיָּבֹ֙אוּ֙ בְּנֵ֣י הָאֱלֹהִ֔ים לְהִתְיַצֵּ֖ב עַל־יְהוָ֑ה וַיָּבֹ֥וא גַֽם־הַשָּׂטָ֖ן בְּתֹוכָֽם׃
Here this word is read "HaSatan". In Hebrew, the definitive article is "ha". "HaSatan" is "The Satan" or, more appropriately, "The Adversary". It is apparent that God created a "Satan", adversary, to act as provocateur that He might test Job. This angel is subservient to God and is not the powerful anti-God we see in Christianity.
Indeed - a belief in the Christian Satan is in direct opposition to God's proclamations that He is One, there are no others, that He alone creates peace and brings darkness, He alone creates light and works evil -
Isaiah 45:7 said:
I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
I will move away from scripture to provide the link to the Universal Jewish Encyclopedia to, again, demonstrate that this is a well-known and understood myth. Satan and Lucifer are not the same beings. Satan is a job many angels hold, though one in particular has the job permanently, whereas Lucifer is a character in a fairy tale.
