The cathedrals are those churches in which the bishop sits, and where he has his chair; this would be the main building within a diocese. These are quite common in religions that are derived from the Catholic religion, and it teaches Christian doctrine, as well as how to live a life of faith. In each of this there is a chair, that is, the chair where the bishop must sit during liturgical services. The word cathedral originates from the Greek “καθέδρα” (cathedra), which refers to the aforementioned seats of the main clergy.
At first the churches destined for the main cells of the church did not have characteristics that differentiate them from the others. However, in the 9th century, their dimensions and structure acquired properties that distinguished them from the others, coinciding with the rise of typical Gothic art in the 13th, 14th, and 15th centuries. From this, the grandeur with which they were built made the city where they were located acquire prestige, so that the artists made more and more efforts to capture magnificence in their works. During this time, classes in theology, Latin and grammar were taught; this marked the origin of cathedral studies, which would soon evolve into universities.
It should be mentioned that the dioceses are one of the units in which each of the cells that make up the sacred temples of the Christian religion are grouped; the organization is established as follows: a temple or church belongs to a parish; this, in turn, becomes part of a deanery or, rather, of an arciprestazgo; in groups, they go on to form a diocese; then the ecclesiastical provinces are formed, which are administered by an archdiocese. For dioceses, there is a bishop, the manwho is responsible for transmitting each of the knowledge he has about the faith in the cathedral for him. This organization has its origin in Ancient Rome, although by then it had a strictly political purpose.
