A8 is right. Your formulation is almost identical to the distinction Nestorius drew between the Divine Logos and the one from the Virgin.
If you don't believe there are two persons in Christ, and do believe that the Divine Logos and Jesus Christ are the same person, then you ought not use language that has the force of denying the unity of Christ's person. If you stop using such language now that the problem has been pointed out to you, you are not a Nestorian. No one is a heretic unless they persist in their erroneous views willfully after receiving correction from the Church (and you'll note, the East and the West are speaking with one voice on this).
Are you the church that you are now correcting him?
That is fine. I would be more than willing to change the way I am phrasing something if it is giving the wrong impression. I do not think Christ was two persons. He was one person with two natures, fully united. How do you describe what happened when Jesus prayed? Was He talking to Himself? When I answered this I was immediately called a Nestorian and an Arian. I am happy to learn. :)
