The keys are powerful because we call to the Gods and we intend these prayers to reach them when we do.
As for the Enochian in the literal sense, I would say they are outdated. The original keys were also very blasphemous to the Gods, and we have changed them.
They have energy into them that is for sure. I myself have used them over the years, but I do not believe they are legitimately the language of the Demons.
The JoS is undergoing revisions and we do not have much time to put things up there.
While I do not believe the Enochian keys are so bad, the thing is, they were created by the characters stated. They do not reflect the most powerful spiritual language, nor the language of the Demons. Enoch-Ian is actually the language claimed of Enoch the biblical patriarch. The Enochian became part of the Satanic subculture and Satanists have used them over the centuries, but I do not believe personally their root is so legitimate, or worth engaging too much into.
As it say in the JoS they have been completely revised anyway. So safe to use. But I wouldn't spend too much time on them personally. So as a final verdict these are inundated right now same as some other pieces of information. Nothing bad or dangerous to use them, but there are other and more powerful things to do.
The JoS is undergoing revisions all the time, like meditations etc.
1 RTR > 100 enochian keys.
If one wants to please the Gods, do an RTR instead. The Gods pay more attention to this rather than any "Enochian".
