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?

Work with the grimoires as best as you can, as much as you can follow along without doing something too drastic to your beliefs (a vegetarian wouldn't be expected to sacrifice an animal like ) but change the god names to something you work with.

If you're not jewish, you're not expected to call on that god. Call on a god that you are devoted to or work with and is in agreement with being called on for evocations.

Mr. Curi, no offense, but the old school magicians were most likely church going devout catholics (or priests themselves). Naturally their conjurations worked for them.
It's unfair to say that everyone has to use those same conjurations just because it's in a book.

Summoning spirits is a decent book, but it's best you choose some method for yourself after plenty of conversations with other magicians and decide on what works for you to work with the spirits. Or ask the spirits themselves with a pendulum, or skry the answer.
At least summoning spirits explains how to skry and develop astral senses, that's useful info.

The other useful bit about the book is that you do not need to physically manifest spirits at all. It's not nearly as easy as most people make it out to be, and following a grimoire to the letter does not guarantee it either.
