Darked, no offense but show me facts. That story is thrown around quite a lot and there is absolutely nothing writen in the past to support those claims. Your statement has just as much validity as the flying spaghetti monster.
I respect all people's beliefs but you speak as though youre explaining truth. Unless you have historical sources that state Lucifer = Satan it stands that your statement is a mistake in translation twisted into what is wrongly taught as "fact". Morning star, the same word used to explain Jesus further into the bible was describing a king, not satan. The story of fallen angels (not one named Morning Star, Lucifer, or Satan) is in the Book of Enoch which is not apart of the Bible. And is against traditional Christian belief to accept any truths besides those within the Bible itself. Catholocism's add ons are Vatican added "truths" which mostly are taken by Babylonian, Egyptian, and Greek religion (Paganism)
