The life suitable for noetic nature is participation in God. Each thing has its appropriate organ. The appropriate organ for the enjoyment of light is man's eye and not his finger or any other member of the human body. So it is that vision of God takes place through the noetic in man. Therefore life is participation and communion with God. And naturally this participation is knowledge of God at the depth at which the soul is able to contain it. Ignorance of God, of course, means non-participation in God.
+Metropolitan Hierotheos of Nafpaktos, from Life after Death, Section 2 chapter 7
