The etymological origin of the word demonology is found in the Greek and more exactly in the union of two words. On the one hand, it is daimon which means “genius” or “demon” and on the other lodge which would come to be translated as “science”. In this way it would be determined that demonology is the science that studies the nature or qualities of the devil.
It is important to underline before going into the deeper definition of the concept that concerns us that “demon” in the past, in Greek culture and before Christianity, was a word that was used to define a deity of a lesser type, whether good or bad. However, this concept was established as something absolutely negative, as diabolical, when the arrival of the aforementioned religious doctrine occurred.
The demonology is the sector of the theology that is dedicated to the analysis of got damn. His studies are related to those of the angelology, a discipline focused on the study of angels. “Malleus Maleficarum”, from Heinrich Kramer and Jacob Sprenger, is one of the key works of Western Christian demonology, where they refer to the existence of the witchcraft as a central aspect of the beliefs of Catholicism and as a potential harm to believers.
Demonology is in charge of assembling lists to name and draw a hierarchical order of the wicked spirits. In this sense, it is the discipline that is opposed to angelology, a framework in which a similar work is carried out but focused on kind spirits.
The precepts of Christianity indicate that demonic entities are angels that fell from heaven. The fall, therefore, occurs when the angel is expelled from paradise for not respecting the orders of God. Theologians attribute this rebellious behavior to what is known as free will or not understanding the dispositions of the Supreme Being.
Anyway, it is interesting to note that the bases that nucleate references of demonological profile present knowledge that was obtained from those who claim to have the ability to invoke evil spirits. This facet of demonology is exploited by grimoires of occult magic.
It is important to underline the fact that throughout history the devil has been represented in very different ways and has also adopted very different names. Thus, in the Bible we can find it under the name of Satan, Devil, Belial, Beelzebú, Prince or even The Dragon.
A book that, the basis of the Christian religion, where you can contemplate duality, the eternal struggle between Good and Evil that is represented by that aforementioned demon and whose clear mission is to carry out the perdition of human souls. However, as is known in the Bible, it is established that Christ is the Savior of those, who manages to defeat the devil and resuscitate.
The main monotheistic religions share the belief about a malefic entity of supernatural order, who performs in a manner contrary to what a God of good intentions intends. However, these entities do not become Gods, since the very essence of these religions implies the impossibility of the existence of two deities of equal power that, in addition, are in conflict.
