Do you see what I mean? In an attempt to highlight the hypostatic union of the human and divine natures in Christ, the diagram does the following:
Divine Nature (God the Son) + Human Nature = Person of Christ
What’s wrong with that? Well, it’s true, Jesus is true man and true God; His One Person consists of two natures – one human and one divine. But that’s not the problem with the equation (and the diagram from the book). No the problem is where it locates God the Son.
