At this season of celebrating the coming of Jesus as man, I thought it would be appropriate to discuss the importance of the Incarnation. This is the third and final segment. Find the link to the article at the bottom.
Christ Is Only One Person
What we have seen so far about the deity and humanity of Christ shows us that Christ has two natures — a divine nature and a human nature — that each nature is full and complete, that they remain distinct and do not mix together to form a third kind of nature, and that Christ will be both God and man forever.
But if Christ has two natures, does this mean that he is also two people? No, it does not. Christ remains one person. There is only one Christ. The church has historically stated this truth in this way: Christ has two natures united in one person forever.
At this point we find another heretical view to beware of. This view, while acknowledging that Jesus is fully God and fully man, denies that he is only one Person. According to this view, there are two separate persons in Christ as well as two natures. In contrast to this, the Bible is very clear that, while Jesus has two natures, he is only one Person. In other words, what this means is that there are not two Jesus Christs. In spite of the fact that he has a duality of natures, he is not two Christs, but one. While remaining distinct, the two natures are united together in such a way so as to be one Person.
To put it simply, there is a certain sense in which Christ is two, and a different sense in which Christ is one. He is two in that he has two real, full natures — one divine and one human. He is one in that, while remaining distinct, these two natures exist together in such a way so that they constitute “one thing.” In other words, the two natures are both the same Jesus, and thus are one Person. As the Chalcedonean Creed says, Christ is “to be acknowledged in two natures . . . 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 . . .”
Evidence That Christ Is Only One Person
We will look at three pieces of the biblical teaching that, while Christ has two distinct and unchanged natures, he nonetheless remains one Person.
1. Both natures are represented in Scripture as constituting “one thing;” that is, as united in one Person. We read in John 1:14, “And the word became flesh and dwelt among us.” Here we see the two natures: the Word (his deity) and flesh (humanity).
2. Jesus never speaks of himself as “We,” but always as “I.”
3. Many passages refer to both natures of Christ, but it is clear that only one person is intended. Galatians 4:4). “. . . who, although he existed in the form of God, did not regard equality with God a thing to be grasped [that is, exploited to his own advantage], but emptied himself, taking the form of a servant, and being made in the likeness of men” (Philippians 2:6–7).
We have seen the biblical evidence for the fact that Christ is God the Son, that he has both a divine and human nature, that each nature is full and complete, that each nature remains distinct, that Christ is nonetheless one Person, and that things which are true of one nature are true of the Person.
The relevance of these truths to us should go without saying. For they go to the very heart of who Christ is. Knowing these truths will greatly affect the way you view Christ and will make the gospel accounts of his life come more alive. As such, this understanding will deepen our devotion to Christ.
Second, having this richer understanding of the incarnation of God the Son should greatly enhance our worship. We will have great marvel and gladness at the fact that the eternal Person of God the Son became man forever. Our recognition of Christ’s worth will be heightened. And our faith in him will be strengthened by having this deeper understanding of who he is.
The union of Christ’s deity and humanity in one Person makes it such that we have all that we need in the same Savior. How glorious! Because Jesus is God, he is all-powerful and he cannot be defeated. Because he is God, he is the only adequate Savior. Because he is God, believers are safe and can never perish; we have security. Because he is God, we can have confidence that he will empower us for the task that he commands us for. And because he is God, all people will be accountable to him when he returns to judge the world.
Because Jesus is man, he has experienced the same things that we do. Because he is man, he can identify with us more intimately. Because he is man, he can come to our aid as our sympathetic High Priest when we reach the limits of our human weaknesses. Because he is man, we can relate to him — he is not far off and uninvolved. Because he is man, we cannot complain that God does not know what we are going through. He experienced it firsthand.
Finally, we need to be ready to defend the truth of Jesus’ deity, Jesus’ humanity, and their joining without confusion in one Person. Therefore, consider committing to memory many of the verses which teach that Jesus is both God and man, and be able to explain the relationship between Christ’s two natures to others.
May we look forward to the day when we see him face to face. Until then, may the joyful hope of this day inspire in us a great diligence in serving and worshiping him.
