Here is another example of hypostatic union being used analogously:
The Council's position is a natural corollary to the earlier Chalcedonian proclamation of the divine and human natures co-existent in Christ, without confusion, without change, without division, without separation..." Since we are called to a similar hypostatic union in Theosis, our will in this world, our action in this world is not be at the mercy of God's will, but to cooperate with it. The principal of synergy. We cannot passively allow evil to win. We must act. In a fallen world, that action will, at times, entail direct, physical confrontation. At times that means we must fight and even kill. The reason for the killing is altogether different however. Evil kills for the sheer joy of killing, to spread discord, terror and confusion. The confronter of evil kills as a last resort and only because of the continued resistance of the evil doer. Not unlike Christ's judgment of us. We are consigned to hell only because of our obstinate refusal to repent.
