He wasn't too happy with my answer. In fact, there is a connection between faith and reason. I'll refer to mathematics. There are numerous theorems in the higher maths which are accepted as truths, while at the same time, they are acknowledged to be theorems. That is, ideas of the truth.
Theology is the same way.
Aquinas is very rational in his explanation of theology, yet this is his theory. He has a theory of the existence of God and of law and of human acts. He arrived at this theory the same way a good mathematician arrives at his. He took what he knew to be true and expounded upon it by way of reason. Aristotle explained that men gain experience through senses and wisdom through contemplating those experiences.
