Fully Divine and fully Human. Human, all too human…
Hypostatic union (from the Greek: ὑπόστασις hypóstasis, 'person, subsistence') is a technical term in Christian theology employed in mainstream Christology to describe the union of Christ's human nature and divine nature in one composed hypostasis, or individual personhood.
In the most basic terms, the concept of hypostatic union states that Jesus Christ is both fully God and fully man. He is simultaneously perfectly divine and perfectly human, having two complete and distinct natures at once.
The Athanasian Creed recognized this doctrine and affirmed its importance by stating:
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.
Dyophysitism (/daɪˈɒfɪsaɪtɪzəm/;[2] from Greek δύο dyo, "two" and φύσις physis, "nature") is the Christological position that Jesus Christ is in two distinct, inseparable natures: divine and human. It is accepted by the majority of Christian denominations, including the Catholic Church, Eastern Orthodox Church, Church of the East, Anglicanism, Methodism, Reformed Christianity and Lutheranism. It is rejected by the Oriental Orthodox churches, who hold to Miaphysitism—that Jesus Christ is of two natures united into one composite nature—while rejecting Monophysitism as heresy along with other extant denominations.
Dyophysitism stands in opposition to the views of monophysitism, the doctrine of Jesus having a sole divine nature, and miaphysitism, the doctrine that Christ is of both divine and human natures fully united into one composite nature. The Chalcedonian definition of dyophysitism holds that the two natures are completely and perfectly united in the one Person and hypostasis of Jesus Christ,[7] in union with each other and co-existing without mixture, confusion or change;[8] the Nestorian definition, on the other hand, holds that the two natures are united in a Prosopic union, as opposed to the Hypostatic union elaborated upon by Cyril of Alexandria and upheld by the Oriental Orthodox Churches.
