The words that we apply to human beings are related to how words are applied to God because there is a casual relationship between these two sets of qualities. Our qualities such as love, power and wisdom are reflections of those qualities of God. AQUINAS uses an example to illustrate this. In medieval times, it was believed that if a creature's urine was healthy then the creature that produced the urine also must be healthy so; 'if the urine is good, then the bull is good.' The bull, after all, produced the urine. Likewise, by examining human love, wisdom or power, we may see a reflection of those divine attributes in God as he is the creator of humanity.
