By Josef Pieper, CERC - If we really think of God as a Who and not a What—in other words, if we think of him as a Someone capable of speech, then there is no “security” against revelation. And man’s only meaningful response to revelation is faith!... The difficulty of discussing proofs and counterproofs in matters of faith lies in the fact that, strictly speaking, faith is not based on proofs, or at least not on factual arguments which can be reduced to precise formulations, and thus cannot be deeply affected by such arguments. Naturally this is a somewhat misleading statement; but we are in deep waters here.
