I just like giving alternative views to promote thought and discussion. From my study of English Literature, and teaching comprehension in elementary school, I know that there is the literal text, and the implied sub-text, as well as the author's intention, the culture, history, and how his readers at the time would have understood it.
So, I accept that the sub-text implication of the passage could well refer to Satan falling from heaven. It is in harmony with the Ezekiel and the Luke references. When we get three passages of Scripture saying basically the same thing, and know that Scripture interprets Scripture, then you could possibly be quite right!
I don't accept that Satan was called Lucifer. Comprehension 101 and basic grammar tells me that a name is capitalised and a description is not. The word "lucifer" is therefore not a name, but a description. Perhaps the description translated "morning star" could very well be ironic or even sarcastic, seeing that Jesus is also described the same way. It could be a way of saying, "So you thought you could be like God, the real Morning Star, but you as "morning star" are just a faint caricature of the real Person."
