I see you are on a mission to evangelize us. Good luck
. You say Allah is one god in the Arab pantheon. Whatever the history of the word is I think that the contemporary defintion is God Almighty, the One and Only. Iam not Muslim but I gather ths is how they perceive It.
You say that Jesus showed us the True God, that of Israel. First off I will tell you that I believe in Christ and the power in its name. I don't believe Jesus is God though. Anyway with that said. The God of Israel had quite a few names. I don't claim to know the defintion of all of them but there were alot of them(names).
YHWH; the "tetragrammation", the 4 consonants standing for the ancient Hebrew name for God also referred to as Yahweh. Since
YHWH was considered too sacred to pronounce, the term
Adonai (my Lord) was used.
According to another source, adonai was on e of the 7 elohim or angels of the presence( creators of the universe) in Phonecian mythology. Adonai is also an angel invoked in the conjuration of Wax (in Solomonic magic operations) and in exorcisms of fire.
In Ophite Gnosticism, Adonai is one of 7 angels generated by Ildabaoth.
El Shaddai;appears in Exodus 6:3, Gen 17:1 among other places. It is translated God Almighty. There is some dispute though, some sources indicate that El Shaddai was a "mountain God."
Elohim, in Hebrew stands for Jehovah(YHWH) in the singular or plural. The term derives from the female singular "eloh" plus the masculine plural "im", God thus being conceived originally as androgynous.
In I Samuel 28:13, where the woman(not the witch) of Endor tells Saul, "I saw gods (the Hebrew gives elohim) ascending out of the earth", the word would seem to designate spirits of the departed(from below not above) rather than gods or God.
Eloi- one of the seven angels created by Ildaboath.
Interestingly Jesus yells with his final breath, " Eloi Eloi, lama sabachthani."
