Before explaining any aspect about demonology, it is very important to clearly understand the definition of demonology first. Demonology can be defined as that science that starts as a subdivision of theology, which has the purpose of studying any subject or matter related to demons or evil spirits, and how they influence the life of human beings. Demonology was created centuries ago, and it can even be said that it was defined as science before the strong irruption of Christianity in society.
However, it gained significant relevance during the rise of the Western Christian religion. Because of this fact, the influence of demonology was the cause of the creation of horrible practices such as those described in the book "Malleus Maleficarum", which describes and explains all the information needed to detect demons or witches, and how to eradicate their existence. One issue that is very important to mention is that demonology is considered the counterpart of angelology, a science that studies kind beings like angels.
An important fact to keep in mind is that one should not confuse the concept of demonology with exorcism since both practices are completely different. For people who study the science of demonology, they don't need to be believers or have faith in a religion, these people can be atheists.
However, to practice exorcism it is necessary to have a certain degree of faith and wisdom, as well as possessing a certain rank within the Catholic Church since this is a position that can only be assigned by bishops or the pope himself. Exorcism is a practice that is responsible for combating and expelling the demons, meanwhile demonology is the science that is responsible for studying everything related to them.
Then, once this term is understood correctly, we can say that the demonologist is the person who moves in the field of occultism and is responsible for studying features, characteristics, ways of acting, and any other aspect of the demons. It is very important to mention, that even though western society has a strong fear of demons since they are considered as evil creatures or spirits, the reality is that there are different types of demons regardless of culture, society, or religion. Therefore, demonology is a science that studies a wide universe of information related to demons.
The most well-known demonologists at present are the famous couple Ed and Lorraine Warren, who were initiated in this science during the '60s. They have become a reference in the study of demons, to the point that they are a worldwide phenomenon due to their popularity in recent years because of their books and movies that are based on their most frightening experiences.
The demons are creatures and evil beings that can negatively influence our lives. They can even harm us and our loved ones, both physically and psychologically. When demons affect and risk our safety and that of our loved ones, that is when we can benefit from the presence and work of a demonologist.
However, the reason for the emergence of demonology is also very important. It arises and is created by the church's need to understand and combat evil. Even though demonology was already a term that existed before Christianity, it is during the creation of the Catholic Church that demonology has an important impact on Western society. Through this alternative science, the church has the opportunity to understand demons or any evil spirit and can fight it until it is eradicated.
Likewise, it is also fundamental to refer that demonologists, in some societies are known as "Sorcerers" who intend to study everything related to other worlds or places where there are evil and dangerous beings. In fact, within these societies, demonologists are considered to possess spell casting skills that allow them to invoke or cast out demons, depending on the circumstances. Some believe that because of their profession and the magical practices they perform, demonologists pay a high price that can affect them physically and emotionally.
However, a real fact of demonologists is that they also study other types of sciences such as anthropology, theology, mythology, sociology, or psychology, which is indispensable for the correct use of demonology. For them, acquiring knowledge of other sciences, including medicine, helps them to differentiate real cases from fictitious ones. Moreover, demonologists not only through other sciences can differentiate real cases from fake ones, but they can also ask for help from the right people.
In the last years, this science has been studied more intensely and how demonologists exercise their profession in the current society. Some demonologists have answered interesting doubts that have been created during years, and that serves to educate people about this science. Among those questions, many have asked themselves the right method to eradicate demons or the areas they most frequent. Most demonologists consider that the only way to eradicate a demon in a person or a house is through exorcism, which can be applied in any culture or society.
Similarly, demonologists also stress that it is very important to learn to differentiate between the symptoms of a disease such as dissociative identity disorder (DID) or any type of disordered disease, with real possessions, as false diagnoses can often be made about a person's condition. In fact, in the past, people suffering from these kinds of disorders or diseases were mistaken for people possessed by demons or for being demonic. This is why some demonologists consider it very important that demonology works in conjunction with medicine and psychology.
Similarly, demonologists consider that it is of the utmost importance that people who want to dedicate themselves to this profession should possess great strength, mentally, spiritually, and metaphysically. It is a profession that requires a great demand that goes beyond the physical, and that can affect the emotional state of any person. For demonologists, demonology is a science that exposes people to unimaginable risks, such as being possessed by a demonic entity. For this reason, most demonologists and many people who believe in the existence of these evil beings, consider that this profession should be taken with great caution and respect.
