You are welcome. I thank you also, because Lucifer being referred to as satan is obviously symbolic also.
But Michael being an arch-angel, who is Jesus, is also obviously symbolic, if one would investigate a little deeper.
From my post #153:
Strong's #746: arche (pronounced ar-khay')
from 756; (properly abstract) a commencement, or (concretely) chief (in various applications of order, time, place, or rank):--beginning, corner, (at the, the) first (estate), magistrate, power, principality, principle, rule.
Mat. 21
[42] Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes?
Jesus is also the firstborn from the dead.
Rom. 16
[25] Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
Eph. 3
[9] And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
Col. 1
[26] Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
However, Jesus gives us a clue in how to locate Him within the OT scriptures.
John 5
[39] Search the scriptures [OT]; for in them ye think ye have eternal life: and they are they which testify of me.
And so I ask, who is "the angel of the LORD", and why would he not give his name, when he was asked?
Ans. His name was being kept a secret.
Judges 13
[18] And the angel of the LORD said unto him, Why askest thou thus after my name, seeing it is secret?
Though many angels have given their names, when they aporoached us, "The angel of the LORD", who is mentioned 50 times in the OT, interacting with and standing for Israel, never did give His name.
As for the name of "Michael", Michael of himself also never gave out his name, though angels (Gabriel) and men spoke of him as "Michael".
So, Who is MIchael? He is only revealed to each of us, who will receive Him.
Mat. 16
[17] And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. Rom. 16:25
