 Though firmly held theological belief is central to it, Aquinas’s understanding of faith is more complicated and nuanced than the view that faith is ‘the theoretical conviction that God exists’. Aquinas holds that faith is ‘midway between knowledge and opinion’ (Summa Theologiae 2a2ae 1, 2 (Aquinas [2006], 11)). Faith resembles knowledge, Aquinas thinks, in so far as faith carries conviction. But that conviction is not well described as ‘theoretical’, if that description suggests that faith has a solely propositional object. For Aquinas, faith denotes the believer’s fundamental orientation towards the divine. So ‘from the perspective of the reality believed in’, Aquinas says, ‘the object of faith is something non-composite’ (hence, definitely not propositional)—namely God himself. Nevertheless, grasping the truth of propositions is essential to faith, because ‘from the perspective of the one believing … the object of faith is something composite in the form of a proposition’ (Summa Theologiae, 2a2ae, 1, 2 (Aquinas [2006], 11 &amp; 13), our emphases).
