to describe the union of Christ's humanity and divinity in one hypostasis, or individual existence. The most basic explanation for the hypostatic union is Jesus Christ being both fully God and fully man. He is both perfectly divine and perfectly human, having two complete and distinct natures at once. The Athanasian Creed recognized this doctrine and affirmed its importance, stating that "He is God from the essence of the Father, begotten before time; and he is human from the essence of his mother, born in time; completely God, completely human, with a rational soul and human flesh; equal to the Father as regards divinity, less than the Father as regards humanity. Although he is God and human, yet Christ is not two, but one. He is one, however, not by his divinity being turned into flesh, but by God's taking humanity to himself. He is one, certainly not by the blending of his essence, but by the unity of his person. For just as one human is both rational soul and flesh, so too the one Christ is both God and human."

''Hypostasis''

Nestorius Nestorius (; in grc, Νεστόριος; 386 – 451) was the Archbishop of Constantinople from 10 April 428 to August 431. A Christian theologian, several of his teachings in the fields of Christology and Mariology were seen as contr ...

in which Nestorius claimed that the term '' theotokos'' could not be used to describe Mary, the mother of Christ. Nestorius argued for two distinct substances or hypostases, of divinity and humanity, in Christ. He maintained that divinity could not be born from a human because the divine nature is unoriginate. The Council of Ephesus in 431, under the leadership of Cyril himself as well as the Ephesian bishop Memnon, labeled Nestorius a neo- adoptionist, implying that the man Jesus is divine and the Son of God only by grace and not by nature, and deposed him as a heretic. In his letter to Nestorius, Cyril used the term "hypostatic" (Greek, καθ᾽ ὑπόστασιν ''kath' hypóstasin'') to refer to Christ's divine and human natures being one, saying, “We must follow these words and teachings, keeping in mind what ‘having been made flesh’ means .... We say ... that the Word, by having united to himself hypostatically flesh animated by a rational soul, inexplicably and incomprehensibly became man.” Cyril also stressed on “μία φύσις τοῦ θεοῦ λόγου σεσαρκωμένη, meaning "one physis of the Word of God made flesh" (or "... of God the Word made flesh")”
