Jesus Christ, True God and True Man
The Belgic Confession states the truth concerning the "Two Natures of Christ" in Article 19:
We believe that by being thus conceived the person of the Son has been inseparably united and joined together with human nature, in such a way that there are not two Sons of God, nor two persons, but two natures united in a single person, with each nature retaining its own distinct properties. Thus his divine nature has always remained uncreated, without beginning of days or end of life, filling heaven and earth. His human nature has not lost its properties but continues to have those of a creature-- it has a beginning of days; it is of a finite nature and retains all that belongs to a real body. And even though he, by his resurrection, gave it immortality, that nonetheless did not change the reality of his human nature; for our salvation and resurrection depend also on the reality of his body. But these two natures are so united together in one person that they are not even separated by his death. So then, what he committed to his Father when he died was a real human spirit which left his body. But meanwhile his divine nature remained united with his human nature even when he was lying in the grave; and his deity never ceased to be in him, just as it was in him when he was a little child, though for a while it did not show itself as such. These are the reasons why we confess him to be true God and true man-- true God in order to conquer death by his power, and true man that he might die for us in the weakness of his flesh.
This doctrinal statement enables us to believe, confess and live that Jesus Christ is true man and true God:
In Jesus Christ there are two natures, divine and human in one single person.
In Jesus Christ there is the uncreated divine nature who fills heaven and earth, the Alpha and Omega, without beginning of days or ending of days.
In Jesus Christ there is a human nature that has a beginning and is finite consisting of a real body. He retains a human body in his death and resurrection.
The divine nature and human nature of Jesus are not separated but remain his in his life, death, resurrection, and ascension.
Jesus Christ is true man that he might pay the penalty for our sins by dying for us in the flesh, and true God that he might conquer our last enemy death by his power.
He has always been, was born, lived, suffered and died, was raised again, and has ascended that we might live forever in him, in his death for our death and in his resurrection and ascension for our abundant and everlasting life. He adorns our humanity with glory in his resurrection. He sympathizes with the weaknesses of our flesh by his mercy and grace. He dignifies our human nature as he unites us to himself so that the life we live in him does not fear the sufferings we suffer in him and the death we die in him.
