I found this interesting blog post at The Archeology News Network called Demonizing the Gods in Jewish and Christian thought. To quote Aleksander Michalak from this short article:
“In the Testament of Job and the Book of Revelation, it was Satan, the Devil himself who was worshipped in the polytheistic temple. In these texts, he is also closely connected with idolatry and is, in fact, responsible for it. In Joseph and Aseneth, however, he is the protector (monarch) of the Gentile (Egyptian) gods […]. In addition, in Jubilees and the 4QPseudo-Daniel the pre-exilic gods of Canaan, to whom Israelites offered child sacrifices, are imagined to be demons”, he continues.”
I find it interesting that the most pagan “demonic” gods were said to be from Egypt, which fits in with Gnostic thought of this time, and the Hermeticism that came down to us today from what i consider to be the ultimate source – Egypt. The inks within the article will take you back to the original sources of this synopsis. The images are open source of various older sculptures.
