Most of Christianity disagrees. That will be evident in the truth that most translations say Lucifer
Did you study that? Let's look:
"How you are fallen from heaven,
O Day Star, son of Dawn! How you are cut down to the ground, you who laid the nations low! (ESV)
"How you have fallen from heaven,
O star of the morning, son of the dawn! You have been cut down to the earth, you who have weakened nations!" (NASB)
"
Shining morning star, how you have fallen from the heavens! You destroyer of nations, you have been cut down to the ground." (HCSB)
"How you are fallen from heaven, O Day Star, son of Dawn! How you are cut down to the ground, you who laid the nations low!" (NRSV)
"How you have fallen from heaven,
O morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!" (NIV)
"How hast thou fallen from the heavens,
O shining one, son of the dawn! Thou hast been cut down to earth, O weakener of nations." (YLT)
"How have you fallen from heaven,
O light-bringer and daystar, son of the morning! How you have been cut down to the ground, you who weakened and laid low the nations [O blasphemous, satanic king of Babylon!]" (AMP)
"How art thou fallen from heaven,
O day-star, son of the morning! how art thou cut down to the ground, that didst lay low the nations!" (ASV)
"How art thou fallen from heaven,
O day-star, son of the morning! How art thou cut down to the ground, that didst cast lots over the nations!" (JPS)
"How you have fallen from heaven, Day Star, son of the Dawn! How you have been thrown down to earth, you who laid low the nation!" (ISV)
Any other versions you want to look at?
but how could a created planet or star rule over the angels and convince a third of them to rebel with it? (Rev 12:4, Isa 14:12, & Luke 10:18)
Because you are reading into the text of Isa. 14:12 an idea that isn't there. It says absolutely nothing about angels, never mind a third of them rebelling.
Do you really think that Satan can properly be called a "light-bringer"?
