As endorsed at the Fourth Lateran Council (1215), the doctrine of analogy insists that God is different from the world that he has created but recognizes that creation bears some relation to it’s Creator. This similarity amid greater difference allows us to use human words and concepts of God yet requires that we always explain how their meaning differs when they are used of God rather than created realities. As Katherine Sonderegger remarks, Lateran IV’s insistence on a “movement frome likeness to unlikeness” is “the scholastic expression of Divine Holiness, the Lordy Act of setting Himself apart.”
