Devil in ChristianityIn Christianity, the Devil is the personification of evil who rebelled against God in an attempt to become equal to God himself. He is depicted as a fallen angel, who was expelled from Heaven at the beginning of time, before God created the material world, and is in constant opposition to God. The devil is identified with several figures in the Bible including the serpent in the Garden of Eden, Lucifer, Satan, the tempter of the Gospels, Leviathan, and the dragon in the Book of Revelation.
The Lesser Key of SolomonThe Lesser Key of Solomon, also known as Lemegeton Clavicula Salomonis or simply Lemegeton, is an anonymously authored grimoire on sorcery. It was compiled in the mid-17th century, mostly from materials several centuries older. It is divided into five books: the Ars Goetia, Ars Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria. It is based on the Testament of Solomon and the ring mentioned within it that he used to seal demons. The text is more properly called "Lemegeton Clavicula Salomonis, or, The little Key of Solomon".
LilithLilith (ˈlɪlɪθ ; Līlīṯ), also spelt Lilit, Lilitu, or Lilis, is a female figure in Mesopotamian and Judaic mythology, theorized to be the first wife of Adam and supposedly the primordial she-demon. Lilith is cited as having been "banished" from the Garden of Eden for not complying with and obeying Adam. She is thought to be mentioned in Biblical Hebrew in the Book of Isaiah, and in Late Antiquity in Mandaean mythology and Jewish mythology sources from 500 CE onward.
BelialBelial (, Bəlīyyaʿal) is a term occurring in the Hebrew Bible/Old Testament which later became personified as the devil in Christian texts of the New Testament. Alternate spellings include Baalial, Balial, Belhor, Beliall, Beliar, Berial, Bylyl and Beliya'al. In the Secret Book of John, an early Gnostic text, the ruler of the underworld is referred to as Belias. Belial is a Hebrew word "used to characterize the wicked or worthless". The etymology of the word is often understood as "lacking worth", from two common words: beli- (בְּלִי "without-") and ya'al (יָעַל "to be of value").
JinnJinn (, ALA) – also romanized as djinn or anglicized as genies – are invisible creatures in early religion in pre-Islamic Arabia and later in Islamic culture and beliefs. Like humans, they are accountable for their deeds, can be either believers (muslims) or unbelievers (kafir); depending on whether they accept God's guidance. Since jinn are neither innately evil nor innately good, Islam acknowledged spirits from other religions and was able to adapt them during its expansion.
DemonologyDemonology is the study of demons within religious belief and myth. Depending on context, it can refer to studies within theology, religious doctrine, or occultism. In many faiths, it concerns the study of a hierarchy of demons. Demons may be nonhuman, separable souls, or discarnate spirits which have never inhabited a body. A sharp distinction is often drawn between these two classes, notably by the Melanesians, several African groups, and others. The Islamic jinn, for example, are not reducible to modified human souls.
