Within Christianity, Nestorianism is a doctrine in which it is affirmed that Jesus Christ forms a being with two completely different natures: that of being human and that of being divine. Others prefer to define it as Jesus Christ dividing his being into two different persons, the one who was born of the Virgin Mary and the one who was molded by God himself. This interpretation is in contrast to the one considered traditional, in which the so-called Messiah is seen as a single being, who balances his mortal condition with the divine powers that were granted to him. This praise comes from the Greek "δύςφύσις", "dys" (two) and "physis" (nature), in reference to the concepts it proposes.
Between the III, IV and V centuries, in the science known as Christology, where the divine and human nature of Jesus are studied, in addition to his participation in biblical events, a debate is opened concerning whether he possesses a nature unique or, well, if it is a being that mobilized on Earth, being mortal and a deity. This had its origin in the interpretation offered by the monk Nestorio, a native of Alexandria, who was appointed at some point as the bishop of the city. Basically, the religious declared that Jesus was simply a man that God had come to dwell in.
The dispute was definitively settled with the Council of Ephesus, where the debate revolved around the title that the Virgin Mary should receive officially, being the Mother of Jesus or the Mother of God. Thus, the nature of Jesus would be fully defined. "Mary, the mother of God", was finally decided as the most consistent with the traditional interpretation of the sacred scriptures. The Nestorians, for their part, were condemned as heretics.
