7] We believe, teach, and confess that now, in this one undivided person of Christ, there are two distinct natures: the divine, which is from eternity, and the human, which in time was received into the unity of the person of God's own Son. These two natures in the person of Christ are never either separated from or mingled with each other, Nor are they changed into each other. Each one abides in its nature and essence in the person of Christ to all eternity.
…11] We believe, teach, and confess also that now, since the incarnation, each nature in Christ does not exist by itself so that each is, or makes up, a separate person. These two natures are so united that they make up one single person, in which the divine and the received human nature are and exist at the same time. So now, since the incarnation, there belongs to the entire person of Christ personally not only His divine nature, but also His received human nature. So without His divinity, and also without His humanity, the person of Christ or the incarnate Son of God is not complete. We mean the Son of God who has received flesh and become man (John 1:14). Therefore, Christ is not two distinct persons, but one single person, even though two distinct natures are found in Him, unconfused in their natural essence and properties.
…44] [Against the false teachers who claim God did not suffer and die for us in Christ Jesus] Dr. Luther also says in his book On the Councils and the Church (1539): We Christians should know that if God is not in the scale to give it the weight, we, on our side, sink to the ground. I mean it this way: if it cannot be said that God died for us, but only a man, we are lost; but if God's death and a dead God lie in the balance, His side goes down and ours goes up like a light and empty scale. Yet He can also readily go up again, or leap out of the scale! But He could not sit on the scale unless He become a man like us, so that it could be called God's dying, God's martyrdom, God's blood, and God's death. For God in His own nature cannot die; but now that God and man are united in one person, it is correctly called God's death when the man dies who is one substance or one person with God. Thus far Luther.
