I ask your forgiveness that a subject so precious was treated so lightly last night. The doctrine of the person of Christ is a treasure, preserved and fought for by the early church. My words were too brief and not precise enough and my diagram lacking. Much of what I will say is taken from Grudem’s Systematic Theology. It has some helpful figures that I will present to you the next time we meet, for now words must suffice.
Grudem gives three inadequate views of the person of Christ:
1) Apollinarianism – This view teaches that Christ had a human body but not a human spirit or mind; that the spirit and mind were from His divine nature. One problem with this is that Jesus would only be a fit redeemer for our body but not our soul and mind which equally need redemption.
2) Nestorianism – Teaches that Christ was two separate persons. This would make Christ a “they” and not a “He”. If you don’t understand this mess or why someone would hold to it – you are not alone.
3) Monophysitism (Eutychianism) – This view teaches that Christ had just one nature. Its like the divine nature and human nature were traveling toward each other at light speed, collided, and a new third nature was all that was left, such that Jesus was not fully human nor fully divine but brand x. Because Jesus is not fully man he is not the perfect substitute or high priest who was tempted in every way we were yet without sin. Nor is He truly God rendering Him incapable of earning our salvation. Mono creates a mut Jesus who cannot save.
Finally Grudem brings us to Chalcedonian Definition as the orthodox statement of the biblical teaching on the person of Christ. The statement is:
We, then, following the holy Fathers, all with one consent, teach men 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 [rational] soul and body; consubstantial (coessential) 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 been handed down to us.
The two natures, human and divine are united in Christ so that He is one person but yet each nature remains truly human and truly divine. His divine nature is exactly the same as the Father, and His human nature is exactly like ours excepting sin. Grudem goes on to explain that “one nature does some things that the other nature does not do” and yet “everything either nature does the Person of Christ does”.
Finally two statements that help me greatly are: 1) Remaining what he was, he became what he was not. 2) This excerpt from the The Athanasian Creed:
33. Equal to the Father, as touching his Godhead; and inferior to the Father, as touching his Manhood.
34. Who although he be [is] God and Man, yet he is not two, but one Christ;
35. One, not by conversion of the Godhead into flesh, but by taking assumption of the Manhood into God;
36. One altogether, not by confusion of Substance [Essence], but by unity of Person.
37. For as the reasonable soul and flesh is one man, so God and Man is one Christ
