i was wondering because im reading this book on magical evocation and The only reason spirits come is because u have GOD there and ur channeling his energy to evoke the spirit.
This was written by pope Honorius
I,X.[the magicians name], do conjure thee, O spirit N.[The spirits name], by the living GOD, by the true GOD, by the holy and all-ruling GOD, Who created from nothingness the heaven, the earth, the sea and all things that are therein, in virtue of the Most Holy sacrament of the Eucharist, in the name of Jesus Christ, and by the power of this same Almighty son of GOD, Who for us and for our redemption was crucified, suffered death and was buried; Who rose again on the third day and is now seated on the right hand of the creator of the world, from whence He will come to judge the living and the dead.

crazy it was writen by a pope.
