What is Advent:
An advent is the arrival, coming, or arrival of someone or something to a place, office, or position.
The word, as such, derives from the Latin verb I will come, which is formed with the prefix ad-, which means 'towards', and the root I will come, which translates ‘come’, and we can translate it into Spanish as ‘arrive’.
The word advent is a cultism, less used than its synonyms arrival or coming, therefore it is restricted above all to more formal communication situations or specific events.
For example, there is talk of advent in reference to the accession of a pope to office: "The advent of the new High Pontiff Francis aroused much joy."
We also speak of advent in reference to the coming to power of a king or a royal house. In Spain, for example, there is talk of the advent of the Bourbon house, which occurred in 1713, after a war of succession that led to the accession to the throne of Felipe V.
In the Judeo-Christian tradition, the arrival of the messiah is also known by the name of advent, which, in the case of Christianity, is represented in Jesus Christ.
Advent of Jesus
In Christianity, it is known as the advent of Jesus or Christ, the arrival of the announced messiah. In the Christian liturgical year, the preparation for the arrival of Jesus Christ begins in the Advent period, which is marked from the four Sundays before Christmas, which is the date marked for Advent.
