This can be the case only because Christ is God’s only Son, who himself shares in the divine nature. Admittedly, Jesus and his apostles do clearly state that he was clothed with this kingly authority as the Son of Man. As the Son of God, as the second person of the Holy Trinity, no authority could have been given to him since he has that authority in and of himself. Nevertheless, also as the Son of Man he continues to carry his divine nature in him. He humbled himself with respect to the state of divine glory and was found in the form of a humbled humanity, but he could not put off his divine nature. It may have been veiled, it may have been muffled, but it never departed from him for even a moment. This is the very reason why divine authority reigns at the same time also in his kingly dominion as the Son of Man. In him the two are inseparable from each other. We cannot penetrate deeper into this, for who can even haltingly describe the relationship in the divine Triune Being between Father, Son, and Holy Spirit?
For that reason, it is enough for us that when the apostles portray that divine dominion for us, they always go back to the divine power through which Christ as the Son of God created all things, while being and remaining the reflection of God’s glory and the express image of God’s being. Because of that, we not only owe our origin to him, but even now continue to exist through him. Thus there can be no separation or contrast between the authority of God and the authority of Christ.
