@CyberLord . Decent books on recent Christian Magick are hard to find.
You will find a lot of crap.
Many of the old grimoires we use today were written by “Christians.”
Pow-wow and Hoodoo have many Christian elements.
The Long Lost Friend (Pow-wow)is easily found online for free.
For Pennsylvania German Braucherei(Pow-wow), I highly recommend,
The Red Church or the Art of Pennsylvania German Braucherei by C. R. Bilardi
and Hex and Spellwork: The Magical Practices of the Pennsylvania Dutch by Karl Herr
The Sixth and Seventh Books of Moses edited by Joseph Petersen. Awesome edition and has the most legible seals of any book on the same subject.
As far as Coptic Magick, you are kind of out of luck unless you want to read
Ancient Christian Magic: Coptic Texts of Ritual Power by Marvin Meyers.
I didn’t like it. You might.
If you want Catholic Magick, go for Jason Spadafore’s books(Brother Ada/Agostino) as I recommended in an earlier reply. Excellent scholar.
You can find some of these books on Scribd and many others at Sacred-Texts dot com
The best book on Christian Magick that I have found is,wait for it,THE BIBLE!!!.
I know you’ve heard it before, but the Psalms are VERY EFFECTIVE.
Especially the Imprecatory Psalms.
Even without a bunch of trappings(specific names of God, candles and their colors, oils and herbs),they can get small jobs done in a pinch. Best Christian Cursing Around!!!
Turn the other cheek you say? Hell no!
Go look at Psalm 109 and then give someone a serious beat down.
