A Domino factum est istud; and how He does it, there are guesses many, but no man knoweth. We must not confound guesses as to the pôs (the manner how) with articles of faith as to the hoti (the fact). We repeat the accredited phraseology of the Church: we believe in that phraseology as expressing truth in the best terms of human intelligence, with an expression accurate and correct, yet inadequate in respect of the further fulness that lies beyond our ken. So we wait in adoration behind closed veils, till the veil be rent and Christ revealed. The scoffer, on the contrary, has made up his mind on what he does not comprehend: in the darkness he has defined for himself one dogma, the absolute incredibility of Christian teaching.
