How is the soul cured?
First we must emphasize the right faith. We Orthodox attach great importance to preserving the faith, just because we know that when faith is distorted, the cure is automatically distorted. We have previously emphasized that theology should be interpreted as medicine. Medical science has the healthy person in view when it tries to guide the sick person to health by various therapeutic methods. We can say the same thing about theology. Theology is the teaching of the Church about spiritual health, but also shows us the path which we sick must follow in order to be healed spiritually. That is why we Orthodox put great emphasis to keeping doctrine intact, not only because we fear the adulteration of a teaching, but because we thus lose the possibility of a cure and perhaps even salvation.
