Unbelievers are in ignorance of things that are of faith, for neither do they see or know them in themselves, nor do they know them to be credible.

Context

“Nevertheless that which is proposed to be believed equally by all, is equally unknown by all as an object of science: such are the things which are of faith simply. Consequently faith and science are not about the same things. Reply Obj. 1: Unbelievers are in ignorance of things that are of faith, for neither do they see or know them in themselves, nor do they know them to be credible. The faithful, on the other hand, know them, not as by demonstration, but by the light of faith which makes them see that they ought to believe them, as stated above (A. 4, ad 2, 3) . Reply Obj. 2: The reasons employed by holy men to prove things that are of faith, are not demonstrations;” source
