So much has been distorted, warped and perverted by enemy religions. Here is the original meaning of Daemon/Demon-
Daemon: "In Greek myth, an intermediate spirit between men and Gods. Daemons such as the one who guided Socrates act as councilors and guardians to human beings."
Another definition from Encyclopędia Britannica, 1973 edition:
"A general Greek term for a supernatural power. As early as the Hesiod, the dead of the Golden Age became daemons, and later philosophical speculation envisaged these as lower than the Gods, but as superior to humanity. The Christians therefore attributed the actions of the Pagan Gods to daemons, identified as fallen angels."
With the coming of Christianity, the Original Pagan Gods were blasphemed as monsters. The above quote from the Encyclopędia Britannica claims that Daemons are lower than Gods. This is partially true in that some are human hybrids [Demi-Gods] who have become both spiritually and physically immortal and have what is called "supernatural powers." The Demons of the Goetia are all Original Pagan Gods. Some such as Asmodeus are Demi-Gods.
This excerpt quote from the Catholic Encyclopedia is very revealing:
In the same way the Greeks and Romans may have worshipped their divinities, fondly believing them to be good. But the Christian Scriptures declare that all the gods of the Gentiles are demons.
