The connection between Lucifer and Satan?

Are Lucifer and Satan totally different entities, or the one and same, or is there just some connection between the two? I’ve heard you Eric say in some of your interviews that you don’t resonate at all with Satan, but then again you did give possibility to people to make a pact with Lucifer through you. Most confusing to me is that in your book Evoking Eternity there is given a sigil for summoning Satan and it’s the very same sigil as Lucifers. There also seems to be many different opinions in different satanic orders about how Satan relates to Lucifer. What is your view on this?
