Charges of Nestorianism are floating about with rather alarming looseness.
Folks, one isn’t Nestorian unless one believes in Christ having two separate persons. And it isn’t Nestorian to say that something can happen to one nature and not the other, any more than it is Nestorian to say that Jesus sometimes acts according to one nature, and sometimes acts according to the other nature. What is true for the activities of Jesus is also true of the passivities, especially since Jesus actively took upon Himself the suffering.
One must make a distinction, if you will pardon the pun, between the distinction of Christ’s two natures (which is Chalcedonian!), as opposed to the separation of the two natures (which is Nestorian). But again, here we must say that just because something happens to one nature and not the other does not mean that we are separating the two natures. That is a definite confusion I am seeing in some of the comments. Just because one does not scrape one’s violin bow across the tuning pegs of a violin does not mean that one has separated the violin strings from the tuning pegs. Now, every analogy will break down, of course. My only point here is that positing suffering of only the human nature of Christ does not constitute Nestorianism in any way, shape, or form.
