I was wondering, are the goetias directly linked to the christian form of satan/lucifer? Basically what I'm wondering is that if goetias exist, is this proof of god/satan? Or are they a totally seperate entity from that? Does saying gods name to them have any sort of affect? or are they prechristian?

I've been looking into summoning andromalius to return some stolen goods to me, but after reading how complex some of the results have been, i know that I am not yet prepared, I intend to begin studying the lesser keys of solomon but I do not know what else I should be studying, where do i find the LBRP, what techniques can I use to empower myself or learn to see more energy?
