The Chalcedonian doctrine of the Hypostatic Union states that Jesus Christ has two natures, divine and human, possessing a complete human nature while remaining one divine hypostasis. It asserts that the natures are unmixed and unconfused, with the human nature of Christ being assumed at the incarnation without any change to the divine nature. It also states that while Jesus Christ has assumed a true human nature, body and soul, which shall remain hypostatically united to his divine nature for all of eternity, he is nevertheless not a human person,[7][8][9][10] as human personhood would imply a second created hypostasis existing within Jesus Christ and violating the unity of the God-man.
The Hypostatic Union was also viewed as one nature in Roman Christianity by a minority around this time.[11] Single-nature ideas such as Apollinarism and Eutychianism were taught to explain some of the seeming contradictions in Chalcedonian Christianity.
