Christian demonology is the study of demons from a Christian point of view. It is primarily based on the Bible, the interpretation of these scriptures, the writings of early Christianity philosophers, hermits, and the associated traditions and legends incorporated from other beliefs.
There have been various attempts at the classification of demons within the contexts of classical mythology, demonology, occultism, and Renaissance magic. These classifications may be for purposes of traditional medicine, exorcisms, ceremonial magic, witch-hunts, lessons in morality, folklore, religious ritual, or combinations thereof. Classifications might be according to astrological connections, elemental forms, noble titles, or parallels to the angelic hierarchy; or by association with particular sins, diseases, and other calamities; or by what angel or saint opposes them.
