I've read Genesis. Lucifer wanted to be God. Unfortunately for him there is only one job opening for God, and it's filled!
I think that's somewhat inaccurate. And in Christian theology, it is not wanting to be like God that is missing the mark. Satan's intent, in this view, is far from seeking to be like God, or to help others be like God. No, just the opposite.
Is it your view that Scientology as contrasted with Christianity wants to help people be "better" and more wise? That Scientology's purpose is to help people become God?
IF so, is this one of the good things of Scientology in your view - and to it's credit over other religions which, in your view, do not wish humans to be "better" and to know more about their true nature?
