The bible states that, “Christ Jesus … being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness.” (Philippians 2:5-7, New International Version ©2011, my emphasis). The Creed of Chalcedon is designed to reflect this concept that Jesus has always had a divine nature and that he took on a human nature. Yet it is important to state that he is not half-God and half-human. Rather in the mystery of the incarnation Jesus remained fully divine but also became fully human. The Athanasian Creed also refers to this subject matter.

The Creed of Chalcedon
We, then, following the holy Fathers, all with one consent,
teach people to confess one and the same Son,
our Lord Jesus Christ,
the same perfect in Godhead and also perfect in manhood;
truly God and truly man,
of a reasonable soul and body;

consubstantial with the Father according to the Godhead,
and consubstantial with us according to the Manhood;
in all things like unto us, without sin;
begotten before all ages of the Father according to the Godhead,
and in these latter days, for us and for our salvation,
born of the Virgin Mary, the Mother of God, according to the Manhood;

one and the same Christ,
Son, Lord, only begotten,
to be acknowledged in two natures,
inconfusedly, unchangeably, indivisibly, inseparably;
the distinction of natures being by no means taken away by the union,
but rather the property of each nature being preserved,
and concurring in one Person and one Subsistence,
not parted or divided into two persons,
but one and the same Son, and only begotten God,
the Word, the Lord Jesus Christ;

as the prophets from the beginning have declared concerning Him,
and the Lord Jesus Christ Himself has taught us,
and the Creed of the holy Fathers has handed down to us.
