Evocation For Non-christians, How do Pagans do it? Options

So I've recently been reading Summoning Spirits. It's an interesting book, but something that struck me is that the rituals in it are as Jewish as the proverbial Bar Mitzvah.

This begs a couple of questions.

1) How do people who adhere to non-Abrahamic religions perform evocations?
2) Are these rituals intended to imply that Judaism genuinely is "the truth," in a supreme or objective sense, to a greater degree than that of other religious systems?

From my experience I have found that although we call these entities by different names they are still the same things a God is beyond any name a human could give. Therefore i see no reason was a Pagan should have any adversion to using Christian diety names or any other religious names, I remember being taught in my childhood that there is One God and Countless faces for that One being. Not everyone is able to or ready to see the same face someone else may, but it's when we realize the Oneness of those many forces that we truly start to know them.

Anyway, there are my two cents hope I didn't offend anyone (IMG:style_emoticons/default/smile.gif)
