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.
Fallen angelFallen angels are angels who were expelled from heaven. The literal term "fallen angel" does not appear in any Abrahamic religious texts, but is used to describe angels cast out of heaven or angels who sinned. Such angels often tempt humans to sin. The idea of fallen angels derived from the Book of Enoch, a Jewish pseudepigraph, or the assumption that the "sons of God" () mentioned in Genesis 6:1–4 are angels. In the period immediately preceding the composition of the New Testament, some sects of Judaism, as well as many Christian Church Fathers, identified these same "sons of God" as fallen angels.
GrimoireA grimoire (ɡrɪmˈwɑr ) (also known as a "book of spells", "magic book", or a "spellbook") is a textbook of magic, typically including instructions on how to create magical objects like talismans and amulets, how to perform magical spells, charms, and divination, and how to summon or invoke supernatural entities such as angels, spirits, deities, and demons. In many cases, the books themselves are believed to be imbued with magical powers, although in many cultures, other sacred texts that are not grimoires (such as the Bible) have been believed to have supernatural properties intrinsically.
EvocationEvocation is the act of evoking, calling upon, or summoning a spirit, demon, deity or other supernatural agents, in the Western mystery tradition. Conjuration also refers to a summoning, often by the use of a magical spell. The conjuration of the ghosts or spirits of the dead for the purpose of divination is called necromancy. Comparable practices exist in many religions and magical traditions and may employ the use of mind-altering substances with and without uttered word formulas.
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.
DemonA demon is a malevolent supernatural entity. Historically, belief in demons, or stories about demons, occurs in religion, occultism, literature, fiction, mythology, and folklore; as well as in media such as comics, video games, movies, and television series. Belief in demons probably goes back to the Paleolithic age, stemming from humanity's fear of the unknown, the strange and the horrific.
GhostA ghost is the soul or spirit of a dead person or non-human animal that is believed to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely, from an invisible presence to translucent or barely visible wispy shapes to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance. Other terms associated with it are apparition, haunt, phantom, poltergeist, shade, specter, spirit, spook, wraith, demon, and ghoul.
ImmortalityImmortality is the concept of eternal life. Some modern species may possess biological immortality. Some scientists, futurists, and philosophers have theorized about the immortality of the human body, with some suggesting that human immortality may be achievable in the first few decades of the 21st century with the help of certain technologies such as mind uploading (digital immortality). Other advocates believe that life extension is a more achievable goal in the short term, with immortality awaiting further research breakthroughs.
Spirit possessionSpirit possession is an unusual or an altered state of consciousness and associated behaviors which are purportedly caused by the control of a human body by spirits, ghosts, demons, or gods. The concept of spirit possession exists in many cultures and religions, including Buddhism, Christianity, Haitian Vodou, Dominican Vodou, Hinduism, Islam, Wicca, and Southeast Asian, African, and Native American traditions. Depending on the cultural context in which it is found, possession may be considered voluntary or involuntary and may be considered to have beneficial or detrimental effects on the host.
SupernaturalSupernatural refers to phenomena or entities that are beyond the laws of nature. The term is derived from Medieval Latin supernaturalis, from Latin super- (above, beyond, or outside of) + natura (nature). Though the corollary term "nature", has had multiple meanings since the ancient world, the term "supernatural" emerged in the Middle Ages and did not exist in the ancient world. The supernatural is featured in folklore and religious contexts, but can also feature as an explanation in more secular contexts, as in the cases of superstitions or belief in the paranormal.
