Doctrines Concerning

Sin

B. That sin originated when Lucifer through pride, rebelled against God, and sought to be like "the Most High God".

Isa 14:12 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!

Isa 14:13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:

Isa 14:14 I will ascend above the heights of the clouds; I will be like the most High.

Isa 14:15 Yet thou shalt be brought down to hell, to the sides of the pit.

Eze 28:11 Moreover the word of the LORD came unto me, saying,

Eze 28:12 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.

Eze 28:13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.

Eze 28:14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.

Eze 28:15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.

Eze 28:16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.

Eze 28:17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.

Eze 28:18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.

Eze 28:19 All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more.

Personal Opinion:

I have always wondered where we get from scripture that Satan is the leader of a pack of rebellious angels. 

The passages cited don't see to quite fit the bill.  They, to me, clearly refer to two very human kings; the first, the king of Babylon (CA 700 BC), the second, the king of Tyrus (Tyre) (CA 586 BC).

I would also like to know how Satan slipped into The Garden of Eden.  Seems like fallen angels wouldn't qualify, wouldn't pass the entrance exam.  However the implication is that the serpent was just one of the many animals created by God for mans' enjoyment.

The relationship between God and Satan in the story of Job is also somewhat a puzzle.  Satan doesn't seem to quite fit the role of an angel fallen beyond redemption.
