Within Christian theology, this is the name given to those desires exacerbated by material and earthly goods, especially those related to carnal pleasures. These, by their nature, are understood as not pleasing to God. It should be noted that, due to the constant and insistent teachings of the Catholic Church on this subject, in which it is preferred to take it as a purely sexual topic, giving rise to a concept plagued with sexual behaviors considered immoral. However, it is known that it represents all desires that should be considered inappropriate for human beings.
This word comes from the Latin "concupiscentia", which can be translated as " burning desire "; the root of this word is also the one that gives life to the word "greed", one of the aspects that is condemned within the Christian tradition. This issue, from the beginning of the Catholic Church, was a somewhat obsessive point for the most important authorities; this, normally, was to keep the lambs that followed religious doctrine pure. To this is added the occasions in which the Holy Scriptures mention that man must always be on the side of good; defeating the serpent. This is also the reminder that the human species is always prone to sin, as a consequence of original sin..
Two types of lust are distinguished: the current one, that in which the desires are disordered or uncontrolled and the habitual one, the propensity to experience that kind of desires. In this way, it is not only possible to distinguish between what has already been mentioned, but also between desires and impulses.
