OK, the Lucifer thing… Might as well get the story from the original source. Here it is, Isaiah 14:3-12
“That thou shalt take up this proverb against the king of Babylon, and say, How hath the oppressor ceased! the golden city ceased!
5 The Lord hath broken the staff of the wicked, and the sceptre of the rulers.
6 He who smote the people in wrath with a continual stroke, he that ruled the nations in anger, is persecuted, and none hindereth.
7 The whole earth is at rest, and is quiet: they break forth into singing.
8 Yea, the fir trees rejoice at thee, and the cedars of Lebanon, saying, Since thou art laid down, no feller is come up against us.
9 Hell from beneath is moved for thee to meet thee at thy coming: it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations.
10 All they shall speak and say unto thee, Art thou also become weak as we? art thou become like unto us?
11 Thy pomp is brought down to the grave, and the noise of thy viols: the worm is spread under thee, and the worms cover thee.
12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!”
In short, God Struck down the King of Babylon who was known as the “Light Bringer” or, in Latin: Lucifer.
