If Christ has one energy, it must be one and the same
energy that performs both divine and human actions. But there is
no existing thing which abiding in its natural state can act in
opposite ways: for fire does not freeze and boil, nor does water
dry up and make wet. How then could He Who is by nature God, and
Who became by nature man, have both performed miracles, and endured
passions with one and the same energy?
