Confessional Corner: Christ’s Personal Union (SD VIII 1-31)
We believe, teach, and confess 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. (SD VIII 11)
