The concept of religion It has its origin in the Latin term religion and refers to creed and dogmatic knowledge about a divine entity . Religion implies a link between man and God or the gods ; according to their beliefs, the person will govern their behavior according to a certain moral and will incur certain rites (such as prayer, processions, etc.).
For example: "Religion is the engine of my life and what sustains me in bad times", "I am one of those who think that religion should not be mixed with the State", "If you have problems, seek refuge in religion".
Such is the influence that religion, regardless of the type, has exerted on the human being throughout the centuries that this has brought with it a large number of situations and opinions that undoubtedly no one has managed to leave indifferent.
Thus, for example, there have been historical figures of great relevance such as the case of the philosopher Karl Marx who did not hesitate a moment to criticize the aforementioned doctrine or set of beliefs. In his most concrete case he defined it as the opium of the people because he considered that the aforementioned religion was to numb the reason of the citizens, was to manipulate them to let their ideas and reasoning be lethargic and thus could not rebel against injustices to those who were subjected or to the oppressors who restrained them at all times.
In the same way, as we have previously emphasized throughout the existence of humanity, there are many wars and conflicts of various types that have been sustained in religion to be carried out. Among them they would highlight, for example, the Muslim Holy War, the Reconquest in Spain or the Crusades.
The latter in particular were a set of military-type campaigns that took place between the eleventh and thirteenth centuries and were aimed at ensuring that Christian armies achieved absolute control of the Holy Land in Jerusalem. Among those stand out, without any doubt, those that today are known as Templar.
According to their way of understanding and accepting divinity, there are different types of religions. The monotheists they are those that are based on the presence of a single God, creator of all things (like the Christianity , he Judaism and the Islamism ). The polytheists , on the other hand, they maintain that there are different gods, which can be placed in a certain hierarchical order (such as Hinduism or the Egyptian and Roman religions of Antiquity). You can also talk about religions pantheists which affirm that the creator and the created objects form the same entity (such as taoism ) and religions non-theists who do not believe in deities of unlimited or universal power (such as buddhism ).
Another classification of religions arises according to their revelation . The revealed religions They are based on the alleged revelation made by a supernatural entity, which orders what the faithful have to believe, what are the rules they must respect and what rituals they have to carry out to pay tribute. mystical religions , on the other hand, can be understood as a philosophy of life and not as a rigid system of precepts and beliefs, while naturist religions neither do they define a belief system, but they recognize the existence of divinities and spiritual entities in nature that manifests in the physical world.
