Abstract
Aquinas accepts the harmony of faith and reason, but he does not think that such harmony is always easily arrived at. After making some background points about his views on faith, reason, philosophy, and theology, I explore two cases drawn from his Christology. In the first, philosophical thinking influences how we understand revelation; in the second, theological thinking influences how we understand a topic normally thought of as part of philosophy. In both cases, harmony is not pre-given but instead arrived at only through a process of adjustment.
