Ialdaboaoth
In Gnosticism, the biblical serpent in the Garden of Eden was praised and thanked for bringing knowledge (gnosis) to Adam and Eve and thereby freeing them from the malevolent Demiurge's control. Gnostic Christian doctrines rely on a dualistic cosmology that implies the eternal conflict between good and evil, and a conception of the serpent as the liberating savior and bestower of knowledge to humankind opposed to the Demiurge or creator god, identified with the Yahweh from the Hebrew Bible. Some Gnostic Christians (such as Marcionites) considered the Hebrew God of the Old Testament as the evil, false god and creator of the material universe, and the Unknown God of the Gospel, the father of Jesus Christ and creator of the spiritual world, as the true, good God. In the Archontic, Sethian, and Ophite systems, Yaldabaoth is regarded as the malevolent Demiurge and false god of the Old Testament who generated the material universe and keeps the souls trapped in physical bodies, imprisoned in the world full of pain and suffering that he created.
However, not all Gnostic movements regarded the creator of the material universe as inherently evil or malevolent. For instance, Valentinians believed that the Demiurge is merely an ignorant and incompetent creator, trying to fashion the world as well as he can, but lacking the proper power to maintain its goodness. They were regarded as heretics by the proto-orthodox Early Church Fathers.
Yaldabaoth is primarily mentioned in the Archontic, Sethian, and Ophite writings of Gnostic literature, most of which have been discovered in the Nag Hammadi library. In the Apocryphon of John, "Yaldabaoth" is the first of three names of the domineering archon, along with Saklas and Samael. In Pistis Sophia he has lost his claim to rulership and, in the depths of Chaos, together with 49 demons, tortures sacrilegious souls in a scorching hot torrent of pitch. Here he is a lion-faced archon, half flame, half darkness. Yaldabaoth appears as a rebellious angel both in the apocryphal Gospel of Judas and the Gnostic work Hypostasis of the Archons. In some of these Gnostic texts, Yaldabaoth is further identified with the Ancient Roman god Saturnus.
