Abstract
Some catholic theologians have considered the concept of faith as a form of knowledge, having, in other words, a propositional nature, but some others have regarded it as something beyond knowledge and non-propositional. Augustine as an advocate of non-propositional faith has taken faith to be a kind of knowledge in the early period of his intellectual life, and hence considered faith and understanding as correlative concepts. But he finally gave up conceptual cognition and regarded faith as something intrinsic based on divine grace and endowment. Thomas Aquinas, however, supporting propositional faith, regards faith as knowledge, but his approach to faith is not only philosophical; rather he also relies on some non-epistemic elements like hope, kindness, and the notion that faith has to be bestowed [by God].
