Augustine on Scripture

"And hence it happened that even Holy Scripture, which brings a remedy for the terrible diseases of the human will, being at first set forth in one language, by means of which it could at the fit season be disseminated through the whole world, was interpreted into various tongues, and spread far and wide, and thus became known to the nations for their salvation. And in reading it, men seek nothing more than to find out the thought and will of those by whom it was written, and through these to find out the will of God, in accordance with which they believe these men to have spoken...But hasty and careless readers are led astray by many and manifold obscurities and ambiguities, substituting one meaning for another; and in some places they cannot hit upon even a fair interpretation. Some of the expressions are so obscure as to shroud the meaning in the thickest darkness. And I do not doubt that all this was divinely arranged for the purpose of subduing pride by toil, and of preventing a feeling of satiety in the intellect, which generally holds in small esteem what is discovered without difficulty....Nobody, however, has any doubt about the facts, both that it is pleasanter in some cases to have knowledge communicated through figures, and that what is attended with difficulty in the seeking gives greater pleasure in the finding.—For those who seek but do not find suffer from hunger. Those, again, who do not seek at all because they have what they require just beside them often grow languid from satiety. Now weakness from either of these causes is to be avoided. Accordingly the Holy Spirit has, with admirable wisdom and care for our welfare, so arranged the Holy Scriptures as by the plainer passages to satisfy our hunger, and by the more obscure to stimulate our appetite. For almost nothing is dug out of those obscure passages which may not be found set forth in the plainest language elsewhere."
