Is Jesus Human?

Jesus has two natures, as defined by the Ecumenical Council of Chalcedon in its Defition of Faith: "...at no point was the difference between the natures taken away through the union, but rather the property of both natures is preserved and comes together into a single person and a single subsistent being; he is not parted or divided into two persons, but is one and the same only-begotten Son, God, Word, Lord Jesus Christ, just as the prophets taught from the beginning about him, and as the Lord Jesus Christ himself instructed us, and as the creed of the fathers handed it down to us." [Decrees of the Ecumenical Councils, ed. Norman P. Tanner]

This doctrine of Jesus having two natures is called 'diaphysitism.' The heretical doctrine is called 'monophysitism' or 'miaphysitism,' which is held by the Oriental Orthodox Churches, who are schismatics. A nature in this context can also be called 'physis,' as seen in the words 'monophysitism' and 'disphysitism.' Monophysitism can be seen in the Gospel of St. John chapter 1, when John says, "In the beginning was the Word, and the Word was with God, and the Word was God...And the Word was made flesh, and dwelt among us..." John shows that Jesus is both man and God, not just God. Moreover, Paul says, "the man Christ Jesus" in 1 St. Timothy ii. 5, showing that Jesus is still both man and God.
