I find the wife swapping incident not at all a reason to disbelieve it. Kelly may have had a bad reputation, but he’s the one that wanted to stop the experiments with enochian and Dee had to persuade him to keep going.
It could have been a form of initiation. As in, learning that nothing is owned by anyone in the highest spiritual realms. This is even mentioned at the end of the biography on Pajl Foster Case in one of the alleged communications they were told some thing similar, which while shocking, and only applicable to those at an extremely high level of spiritual evolution, does make some sense to me.
Paul Foster Case was definitely worried about the use of Enochian. But at his time period, John Dee’s five book of mysteries was not translated and available in the forms it is today. They generally got their info from “A True and faithful relation” which was barely true and faithful, incomplete, and it even seems to be a hit piece.
Today we have much more available to learn about the true origins of Enochian and John Dee. Peterson did an excellent job at translating and adding commentary, I’m in the middle of reading the 5th edition and I’ve realized how lucky I am to have access to as much info as we all do in this time period.
For what it’s worth, I’m not so sure the PELE ring and other paraphernalia are as needed as people think. I believe these were so stressed to John Dee because he was the one bringing in an entirely new magickal system and it was extremely important that none of the direct messaging he got from the angels was distorted or given by an imposter. But after it was all revealed to him, I think it was meant to be used by many more people, and it seems that the language itself has magickal power just by the vibration of the words even if just a fraction of its true power.
I myself am not ready to do any advanced enochian workings. But I do think the small bits and pieces of enochian language and vocalizations are safe that damon brand uses in some books. And as for scrying aethyrs and other more advanced techniques, I’m sure it can be used safely if someone is fully prepared and I’m sure that the system itself is more coherent and tested now with more years of use as well as more complete source material.
