The Bible is the unique and inexhaustible book in which all there is to say about God and man is said. God's presence pervades it. In it are revealed all those aspects of His mysterious being that we are allowed to glimpse; in it He appears, He speaks and He acts. "Man can see himself in it, in all his potentialities, his grandeur and his weakness, from his sublimest aspirations down to those obscure regions of consciousness in which each of us bleeds from the wound of original sin." [Daniel-Rops].
