Every sin consists formally in aversion from God…. Hence the more a sin severs man from God, the graver it is. Now man is more than ever separated from God by unbelief, because he has not even true knowledge of God: and by false knowledge of God, man does not approach Him, but is severed from Him.

Nor is it possible for one who has a false opinion of God, to know Him in any way at all, because the object of his opinion is not God. Therefore it is clear that the sin of unbelief is greater than any sin that occurs in the perversion of morals.

The same conclusion follows from the distinction Modernists make between science and faith. The object of science they say is the reality of the knowable; the object of faith, on the contrary, is the reality of the unknowable. Now what makes the unknowable unknowable is its disproportion with the intelligible - a disproportion which nothing whatever, even in the doctrine of the Modernist, can suppress. Hence the unknowable remains and will eternally remain unknowable to the believer as well as to the man of science. Therefore if any religion at all is possible it can only be the religion of an unknowable reality.
