ABSTRACT

According to Christian doctrine, Jesus Christ is one person who has two natures—human and divine. It is affirmed that he is “truly divine and truly human in two natures” but at the same time “one person and substance.” The Council of Chalcedon declared in 451:

… one and the same Christ … acknowledged in two natures, without mingling, without change, indivisibly, undividedly, the distinction of the natures nowhere removed on account of the union but rather the peculiarity of each nature being kept, and uniting in one person and substance, not divided or separated into two persons, but one and the same Son … 1
