I haven't spoken much about this, but I was questioning my own use of the phrase "God in the Persons," only because I was concerned that people would start thinking that I believe that God only has "three offices," but is not three distinct entities. (i.e. I believe both that God is one God, but also three separate entities at the same time, which is what Jesus taught.) So far, it seems I have been accused of that, when that's not what I believe, but frankly, I cannot find any other way to speak of it in Scripture. I don't know another way to label it yet, and as of now, I don't believe there is a way to label it because the concept is beyond our comprehension; we can accept it, but the full nature of God is something we cannot understand in our current forms in the flesh.
