St. John of the Cross is a good example of one who held this position. Language is univocal. There is no problem. Words which refer to God and to humanity have exactly the same meaning. Carl F. H. Henry holds this position.
Language is analogical.
One can postulate that there is an analogy between what a word means when it applies to humanity and when it applies to God. St. Thomas Aquinas is perhaps the greatest proponent of this perspective. Metaphysical language is meaningless. Only propositions which can be empirically verified have meaning. This is the position of the Logical Positivists.
