Dogma is a term from the Greek, which means thought, principle or doctrine. Dogma is a promise, principle or pact that is established as unalterable and authentic as the irrefutable foundation of a science. On the other hand it refers to the fundamental points of all science, system, religion, etc. but in the religious sphere it is a doctrine or belief of God manifested or exposed by Jesus Christ to man and witnessed by the church.
Dogmas are the doctrines that the church, congregation or Christianity exposes or formulates to be believed, through faith, in an unalterable way, declared by God. This term is also used in the philosophical environment, and affirms that man through reason could know the absolute truth, provided that he uses a series of procedures for it, and an implanted structure of investigation.
Today dogmatism is mostly related to the conceptions of the Catholic Church, for example one of the most common dogmas, is the one that formulates the belief in a unique God is manifested in three persons, that is, in God the creator father from heaven and earth and the whole universe, his son Christ who died crucified for our sins and the holy spirit. The Catholic Church proposes dogmatism as an absolute and irrevocable truth and its devotees must adopt this series of dogmas, and these doctrines cannot be put to the test or doubt, they must be accepted without any type of objection. And it is worth noting that each religion has its own dogmas, not only Christianity but also Judaism, Islam, etc.
