Dyothelitism means that Jesus possesses two wills, one divine and one human. God the Father and God the Son are distinct persons, but they share the same divine will. The difference of Jesus’ will from his Father’s will in Gethsemane is his human will. By incarnation, God the Son took up a second way of living as a man. He now possesses two natures. Each nature is complete, including a will for each. I define will as the spiritual capacity for desires and choice in the exercise of personal agency. A caution to remember is that these are mysterious operations (desiring, choosing) of mysterious realities (persons, wills, Trinity) that may leave us continuing to wonder even after thinking it all through as best we can. We will consider briefly Jesus’ divine will, his human will, the situation of Gethsemane, and how this affects our thinking about the Trinity.
